1. Planning Information
1.1 Areas of application
The flow measurement device in the Flowmeter designed to measure dynamic flow in pipes and tubes. This flow meter is suitable for liquids only. The Flowmeter is used in
Chemicals supply for controlling, logistics, monitoring Cooling systems, logistics, monitoring Process equipment for control and monitoring of formulas Valve control for continuous release of liquid volumes Supply with de-ionized water Very dynamic liquid processes with dosing times of below 1 second
Flowmeter has the following features and benefits:
No movable parts, therefore no wear High repeatability Easy to clean Safe operation Compact design Integrated detection of empty conduits Integrated dosing function with pre-set and adjustable amounts Chemical resistant Constant pipe cross-section over the entire measurement channel
1.2 Measuring principle
It usually takes more energy to swim against the flow than with the flow. The ultrasonic flow measurement is based on the phase-difference approach: Two u ultrasonic 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.
ltrasonic-sensors located opposite from each other alternatively transmitting and receiving
signals. If there is no liquid flow both sensors receive the transmitted ultrasonic signals in

1.3 Operational Safety
Comprehensive self-tests ensure highest possible safety. Faults (process or system errors) are output on a digital output or displayed on the display menu.
The protection class is IP 67. Flowmeter meets the general EMC immunity requirements according to CE, EN 61000-6-3, EN
61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6. Flowmeter meets the safety requirements concerning the Protective Extra Low Voltage directive
according to EN 50178, SELV, PELV.
2. Assembly and Installation
2.1 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.
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.
NOTICE
Fig. 2: Installation position of flowmeter
For fastest possible bubble detection it is important to keep the pipe distance from tank to Flowmeter as short as possible. Accurate measurement can only be assured, if the pipe is completely filled and the liquid does not outgas.

ULTRAFLO 5000
PVDF-PE Plastic Ultrasonic Flow Meter
Notwithstanding it may be advantageous for dosing applications to install the Flowmeter 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.
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.
NOTICENOTICE
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.
Do not exceed the maximum pressure allowance for of the Flowmeter (see section
5.2 Technical specifications). Exceed the maximum pressure can lead to destruction
WARNING!
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 straight and unobstructed flow zones must be:
Nominal Diameter
Inflow distance Outflow distance
DN 5
0cm 0cm
DN 7
0cm 0cm
DN 10
5cm 0cm
DN 15
40cm 20cm
2.2 Assembly of the flow meter
The flow meter is mounted into a pipe system by using the mechanical connection. Flowmeter 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, Flowmeter should be installed on the pressure side of the pump.

ULTRAFLO 5000
PVDF-PE Plastic Ultrasonic Flow Meter
Fig. 3: Mounting examples for Flowmeter
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 Flowmeter.
Fig. 4: Mounting possibilities
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.

3.2 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 Flowmeter 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. Example of operation see appendix.
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
Flowmeter 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 Flowmeter can be reset. Example of operation see appendix
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, Flowmeter runs a self-diagnostic function which optimizes all important parameters. This process lasts approximately 1 minute.
NOTICE
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"
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 flow meter. Changes to a smaller value of the parameter may cause an offset drift what results in a faulty measurement.
There are higher tolerances below the standard default settings, see also section 5.2 measurement errors!

Dosing function
Dosing can be determined in different ways :
1. 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 the display or Programmtool. Dosing starts, as soon as the digital input is wired to 24V, e.g. via a pushbutton. Flowmeter will open the dosing valve via the output configured for it. When the pre-set dosing quantity is released, the dosing valve is closed via the above output. The dosing procedure can also be started and stopped by using the dosing user menu. The second output can be used independently for signaling empty pipe, limit control or flow direction.

2. 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.
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

closing of valves.
Media
Flowmeter comes with a medium matrix with up to 8 interpolation values. Different media can be managed in the sub menu "Media". By using the sub menu point "Correction" it is possible to correct the flow measurement in percent. Example of operation see appendix.
Digital input I1*
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.
NOTICE
When input setting is changed a device restart is required. After restart the changes are activated.

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.

3.4 General Information
Please check the following before powering the flowmeter for the first time:
Check the electrical connections and cable allocations Check the installation position of the flowmeter. Are the direction of the arrow on the name plate and the actual flow direction in the pipe congruent? Is the measurement pipe completely filled with fluid? C
heck the back pressure in the system
When everything has been checked, switch on power. After 30 minutes with power running the measuring device reaches the maximum accuracy.
4. Exchange of Measuring Device
Switch off power before disconnecting the electrical connections! Wiring installation, disassembly and removal must be performed by qualified persons experienced and knowledgeable about electrical work.
WARNING!
Serious injury or death from electric shock may occur if wiring, installation, d
isassembly or remove of wires is performed while electrical power is energized
Please note that after replacing the flowmeter
a) the programming of the previous flowmeter should be saved and copied on the new flowmeter b) when using the dosing function, set a quantity
If the device requires a configuration change, the display and programming unit Programmtool may be required (see section 6. Accessories).

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.
