1.2 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 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.

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.
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
NOTICE
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.
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!
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:

Attention : Only operate the flowmeter Flowmeter within the operating limits stipulated on the product label and the operating manual / data sheet. Use outside these conditions lead to overloads which cause permanent damage.
3. 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.
NOTICE
3.1 Operation
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
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
NOTICE
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:
Digital output Q1, function and behaviour Digital output Q2*, function and behaviour Pulse value Analog output QA Flow range, for which shall apply 4...20 mA Creeping suppression Dosing input I1*, function and behaviour Optimization of measurement curve with up to 8 interpolation values (media matrix)
Described functions that are marked with * are not available for the 5-pin version. The available functions of 5-pin version are described in the connection table on page 7. To change configurations at Flowmeter a Programmtool is needed.

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 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.

10
Page 13
ULTRAFLO 1000
PFA Teflon Ultrasonic Flow Meter
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

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.

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

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.
