Measuring Principle

The ultrasonic flow measurement is based on the phase-difference approach:

Two ultrasonic-sensors located opposite from each other alternatively transmitting and receiving ultrasonic signals. If there is no liquid flow both sensors receive the transmitted ultrasonic signals in the same phase, i.e. without phase difference. If liquid is flowing there is a phase shift. It differs when measured in direction of the flow than when measured against the direction of the flow. This phase difference is directly proportional to the flow rate.

Installation Instructions

The housing of Flowmeter is labeled with an arrow symbolizing the direction of the flow. The flowmeter must be installed in direction of the flow.

Note

• The nameplate of the Flowmeter has an arrow, symbolizing the flow direction of measurement. The flow meter has to be installed in a way so that the flow-through is in the same direction as the arrow symbol.
• For fastest possible bubble detection it is important to keep the pipe distance to UltraFlo as short as possible. Accurate measurement can only be assured, if the pipe is completely filled and the liquid does not outgas.

Notwithstanding it may be advantageous for dosing applications to install. The UltraFlo as close as possible to the dosing valve, since soft pipes increases the cross-section depending on the system pressure. This may lead to repeatable differences.
Note: Insure that no cavitations dissolve from the measured liquid. Depending on the measured liquid it can be helpful to have enough back pressure on the outlet of Flowmeter to avoid cavitations. Insure all mechanical connections are tight.

Particles present in the flow stream may result in measuring errors.

When using pumps, Flowmeter must be installed in flow direction on the pressure side, on order to ensure sufficient pressure. The maximum pressure rating of Flowmeter has to be considered.

Warning: Do not exceed the maximum pressure allowance for of the Flowmeter (see Technical specifications). Exceed the maximum pressure can lead to destruction of the Flowmeter.

For correct volume flow measurements straight and unobstructed inflow and outflow distances have to be observed. Starting from the connection thread these have to be at least:

Nominal Diameter	DN 5	DN 7	DN 10	DN 15
Inflow Distance	0cm	0cm	5cm	40cm
Outflow Distance	0cm	0cm	5cm	40cm

Assembly of the Flowmeter

Note: The flow meter is mounted into a pipe system by using the mechanical connection. UltraFlo should be mounted vertically into the pipe for the best measuring performance. Do not install the flow meter after a dosing valve where the flow meter can run empty. Placing the flow meter after a dosing valve and allowing it to run empty will cause a measuring deviation at the next measurement. To avoid bubbles in the liquid, UltraFlo should be installed on the pressure side of the pump.

• If it is not possible to mount the flow meter vertically, then mount the instrument in a location where the pipe will be filled at all times. The best measuring result is achieved if bubbles do not pass through UltraFlo® 4000 Series.
• For applications with a “clean design“ for which it is necessary to completely drain the pipe system, we recommend mounting the flow meter in the vertical position. Residual liquid may remain inside the device if flow meter is mounted horizontally.
• Vibrations or mechanical forces may decrease measuring accuracy. So if there is due to vibration or mechanical movements is necessary to fix Flowmeter additionally, the instrument can be either mounted on a DIN rail, or be fixed on the lateral slot.

Attention

• Flowmeter must be installed without mechanical tensions on the existing pipe system. The flow meter may be damaged if there is tension on the existing pipe system.

Warning

• Non-compliance of the installation instructions may result in tearing of the housing, liquid may leak out.

Electrical Wiring

Serious injury or death from electric shock may occur if wiring, installation, disassembly or remove of wires is performed while electrical power is energized.

Warning

• Always shut off or disconnect electrical power at service panel and lock switch or breaker and tag to prevent energizing electrical power during work or while Flowmeter is not assembled and installed.

Wiring installation, disassembly and removal must be performed by qualified persons experienced and knowledgeable about electrical work.

Commissioning

NOTE

• If Flowmeter is used for a fluid other than water the “basic trim” has to be carried out during commissioning. Therefor the device has absolutely be filled with medium.
• The basic trim can be done on the device display (alternatively Programmtool). During the adjustment the medium may not flow as it affects the function.

Operation

If Flowmeter is used as volume flowmeter for water or water-like liquids, it will not require on-site calibration. Parameters for water are calibrated at the factory. Notwithstanding the Flowmeter may also be supplied with customized settings. The coordination must be done at time of purchase order.

NOTE: If necessary, e.g. if viscosity and/or speed of sound deviate significantly from water, the pre-set parameters can be adjusted via Programmtool. It is always necessary to adjust the manufacturer pre-set parameters when using the Flowmeter as a dosing device according to section 3.2 (Dosing 1. Flowmeter as a dosing device). Adjusting the manufacturer pre-set parameters requires Programmtool.

The following parameters may be changed to settings suitable for the individual conditions: for 5-pin version

• Digital output Q1, function and behavior
• Analog output QA, function and behavior
• Flow range, for which shall apply 4…20 mA
• Pulse value
• Creeping suppression
• Optimization of measurement curve with up to 8 interpolation values (medium matrix)

Display And User Menu

Flowmeter is equipped with a display to visualize actual measurement values and to change parameters of the flow meter. Menu navigation and parameter changes are controlled by the four keys on the keypad.

• Press the [Set] key to display the main menu. Different menu options can be selected by using the two arrow keys.
• To enter e.g. analog limits “Analog output – Upper limit” use the arrow keys to change values and press [Set] key to confirm. To switch back to the last menu level press the [Esc] key. As soon as the operator tries to change values the user will be prompted to enter a password. Password protection is used to ensure changes to values or configurations are done by authorized personnel.
• The default password for Flowmeter is 41414. The password can be changed with Programmtool. The user level will remain active for 5 minutes after the last press on any button.

Note

• The Password should only be shared with personnel authorized to make changes to setting.

NOTE

• Always the first parameter of the menu appears in the display. This need not be the adjusted enabled parameter. The enabled parameter appears inverted and possibly visible by scrolling.
• Functions marked with asterisk (*) are only available for the Flowmeter 8-pin version. Flowmeter without user display supports the same functions as the display-version. The display and programming unit Programmtool is needed to change configurations of Flowmeter without user display.

Menu Organization for 5-Pin Version

Functionalities of flow meter and default settings

Set Offset

• In the sub menu “Set Offset” it is possible to set the actual offset of the flow meter. Use this function only when UltraFlo is completely filled with liquid, and there is no flow. If the offset is set while flow is present or when the pipe is empty it will cause an offset drift what results in a faulty measurement.
• A small offset change, e.g. caused by variable temperatures, is automatically done by the flow meter. It is also possible to set the offset via the configurable digital inputs.

Language

• The language of the display can be changed. Available languages are English and German.

Filter

• The function ”Filter“ averages the analog output signal. Possible settings: Soft, Medium, Strong, Off.
• The analog output signal reacts faster to signal changes when average determination is set to “soft”. Whereas the analog output signal reacts slower when average determination is set to “strong”.

Units

• UltraFlo is able to show actual flow or the volume in different units. Following units can be selected: ml/s + l , Gal/min +Gal , l/min + l , l/min + m³.
• The first letters correspond to the unit of the flow value. The letters after the + correspond to the unit of the volume value.

Reset Counter

• The volume counter of UltraFlo can be reset.

Important!

• Once reset, counter values cannot be restored. After a reset the counter works normally.

Basic Trim

NOTE

• The “Basic Trim” function insures that the flow meter is conforming to the media specific characteristics.
• To execute this function, UltraFlo runs a selfdiagnostic function which optimizes all important parameters. This process lasts approximately 1 minute.

Important!

• To make sure the basic trim is correctly done, the flow meter has to be filled with liquid without a flow.
• When there is an error detected while performing the basic trim function, the display shows “Error”. After successfully finishing the basic trim function, the display will show “Done”.

Digital Outputs

All outputs switch over to high resistance when the supply is smaller than 18V. When overload or short circuit is detected the digital outputs are switched off after 100μs for a period of 2s. When time is up the outputs get applied again.

Important: When using the dosing function the output should not be configured as normal closed!
If the dosing output is configured as normal closed the valve will stay open after the.

Digital output Q1

Digital output Q1 may be used as pulse output, empty pipe detection, for switching dosing valve or limit control. By using Programmtool the user can switch between npn and pnp-transistor logic. In case of inductive load a diode has to be connected parallel to the coil.

• Setting area: off, pulse output, empty pipe, dosing output, lower limit, upper limit, negative flow.

Digital output Q2*

Digital outputs 2 may be used as pulse output, empty pipe detection, for switching dosing valve, limit control or flow direction control.
See Electrical Wiring table connection
The npn or pnp logic can be selected. When the output is connected to an inductive consumer a diode has to be installed parallel to the load.
Flowmeter via pnp, external counter e.g. PLC

• Setting area: off, pulse output, empty pipe, dosing output, lower limit, upper limit, negative flow

Important

• Inductive load on the digital outputs without an installed diode may cause damage on the Flowmeter electronics. dosing batch.

Dosing Function

Dosing can be determined in different ways:

Flowmeter as dosing device (dosing control via Flowmeter)

Flowmeter controls the complete dosing function. The dosing quantity (e.g. 400 ml) is pre-set in the Flowmeter via Programmtool. Dosing starts, as soon as line start of dosing is wired to 24 V, e.g. via a pushbutton. Flowmeter will now open the dosing valve via the output configured for it. When the pre-set dosing quantity is reached, the dosing valve is closed via the above output. The second output can be used independently for signalling empty pipe, limit control, pulse output or signalling negative flow.

Flowmeter as flowmeter (dosing control via dosing equipment)

The dosing equipment controls the entire dosing function. The dosing quantity is fixed in the dosing equipment control during commissioning by pre-selecting the meter pulses. Dosing starts, when the relevant pushbutton of the dosing equipment is pushed. The control will now open the dosing valve. From now on Flowmeter will send a voltage pulse to the control for each volume unit that has flown through (e.g. per 1ml). When the pre-selected pulse quantity is reached, the control closes the dosing valve. In this case, output 1 is used to send out pulses, output 2 is independently usable for empty pipe detection, limit control or signalling negative flow.

Warning

• The customer has to provide an emergency stop and an overfilling stop to prevent hazardous situations.
• Both functions must perform safety shut down of pumps and WARNING! closing of valves.

Pulse value

This section determines the output settings for pulsed outputs.
Choose configuration such as to neither exceed the maximum output frequency of the Flowmeter (10kHz) nor the maximum input frequency of the control. If the maximum frequency is exceeded the Flowmeter will not output pulses correctly.

Example	2.0 ml/Pulse
This Means	a pulse is emitted every 2.0 ml.
Setting Range	0.1. 3000.0 ml/Pulse, in 0.1 ml/Pulse steps
Default Setting	1.0 ml/Pulse

 

Flow	Pulse value	Frequency	Period	Duration of the Pulse
ml/s	ml/Pulse	Hz	s	s	ms
1	1	1	1	0.5	500
100	1	100	0.01	0.005	5
1000	0.1	10000	0.0001	0.00005	0.05
100	10	10	0.1	0.05	50
0.5	10	0.05	20	1	50

In the last case every 20 seconds, a pulse of 1 second duration is put out.

Dosing

The Flowmeter can be configured for manually dosing by choosing the dosing function via the user display. The Volume “Dosing Batch” and the “Dosing Time” are freely adjustable. When the “Dosing Time” is set to zero, the timer control is inactive. A dosage can be started and stopped with the menu function keys “Start” and “Stop”.

Setting Range “Dosing Batch”	0 – 3500 Liters
Setting Range “Dosing Time”	0 -30000 Seconds
Default Setting “Dosing Batch”	0 Liters
Default Setting “Dosing Time”	3 Seconds

Important

• If Dosing Time = 0 the time switch-off is inactive.

Analog output QA

The analog output is available as current output 4-20mA or 0-20mA. This is selected with the purchase order. As standard it comes with current output 4-20mA. It can also be switched off by using Programmtool.
The current output ranges from 0 to 22.6mA measuring the flow rate or the condition of the flow measurement.

The values here signify for 4-20mA configuration

• 20 mA the upper limit of the relevant measurement
• 4 mA the lower limit of the relevant measurement
• 3.5 mA empty pipe

Upper and lower limit parameters can be set within the type-specific measurement of the device. By default zero flow is set at 4 mA and the maximum flow is set at 20 mA

Setting range	0-20mA, 4-20mA, off
Output value	Flow, Temperature

Important

• When current output is used, the load must not be higher than 500 Ohm. A higher load prevents the device from providing the maximum current of 22.6mA.

Creeping Suppression

The creeping suppression excludes flow measurements that result from convection in a narrow band around zero, even with a closed valve. At the factory, the creeping suppression is set at a standard value in relation to the cross-section of the flowmeter.
There are higher tolerances below the Standard Default Settings.

• Setting range: 0.0…20 l/min, in 0.006 l/min steps
• Default settings: 0.09 l/min for DN7 / 3/8″, LowFlow option 0.03l/min
  • 0.3 l/min for DN10 / ½”
  • 0.9 l/min for DN15 / ¾”
  • 1.2 l/min for DN20 / 1″

The Creeping Suppression Works with a Hysteresis of -25%

Example

• Creeping suppression = 0.6 l/min
• If the flow rate is lower than 0.45 l/min the pulse output/analog output becomes inactive.
• If the flow rate exceeds 0.6 l/min a pulse is output again and added to the totalizer.
• Similarly, a value is transmitted to the analog output again.

Digital input

Flowmeter has a digital input that is programmable to following functions: dosing input, set offset, creeping suppression inactive and reset counter. In order to start a dosing process, 24V DC power is required. The status of the dosing parameters is modified with the Programmtool.

NOTE

• The dosing input is locked so that a re-start is not possible during a running dosing process.
• After changing configurations via Programmtool a restart of the device is necessary to activate the doing input function.

Available Input Functions

	Set offset	Creeping flow off	Dosing	Reset Counter	off
0V	–	–	–	–	–
24V	Rising edge: 0->24V Set offset	State : deactivating creeping flow	Rising edge: 0->24V start dosing	Rising edge: 0->24 Vcounter is reset	–
Run only in stationary medium

The input function “Set Offset” may only be used when there is no flow through the meter. If an offset trim is done while liquid flow is present an offset drift will cause measurement deviations. If the Flowmeter shows an offset drift caused by a wrong offset setting, run the function “Set Offset” or “Basic Trim” again with filled flow meter and no present flow.

• All media must be removed before returning. This is particularly important, if the medium to be measured is health hazardous.

Devices judged to be insufficiently cleaned will be returned to sender. No inspection of device will be done until proper cleaning is completed by user.
Costs due to inadequate cleaning of the instrument for possible disposal or injury (burns, etc.) will be charged to the sender of the meter into account.

Warning

• With the flowmeter send a detailed report describing the failure, the application and the physical-chemical properties of the medium parameters. (e.g. a decontamination declaration).

In order to be able to process your repair order quickly and smoothly it is important that you provide a technical contact person including phone and fax number as well as e-mail address.

Behavior of the Temperature Sensor

The integrated temperature sensor has no direct contact to the liquid and is used to calculate the expansion of the housing. The environment temperature greatly influences the actual temperature of the temperature sensor. The response time of temperature changes relates to the mounting position of the temperature sensor inside the housing.

Step-Response Time

Step-response time after a significant temperature change. (Filter “Off”)

Filter Configurations for Temperature Sensor

Filter	100%
Off	1s
Soft	16s
Medium	1min
Strong	4min

Influence of the environment temperature

In the table below some examples of the temperature influence are shown.
