4 Installation
4.1 Pipe/tube requirements
Correctly sized gaskets
Correct aligned flanges and gaskets
Diameter mismatch at the pipe junctions should be avoided but must be less than 1mm. For
further information see ISO 14511
Ensure clean pipes after installation
.
4.2 Inlet / outlet runs
In order to maintain the accuracy stipulated in the data sheets, the sensor must be inserted in the
centre of a straight pip e section with an undisturbed flow progression.
An undisturbed flow progression is achieved if the sections in front of the sensor (inlet) and behind the
sensor (outlet) are sufficiently long, straight and without any obstructions such as edges, seams,
curves etc.
Therefore, it is necessary to ensure the recommended inlet and outlet runs.

4.4 Installation of the Sensor
4.4.1 Mounting VA 500 onto the ball valve
Assembly is carried out by inserting the connection thread with gasket. (G1/2“
thread, SW 32) into the ball valve with ½"internal thread.
The sensor has be tighten by hand as far as possible and then tighten with
stipulated torque of 25-30 Nm.
It must be ensured that the installation is pressure-tight.
The sensor is then inserted to the required immersion depth (sensor tip in the
middle of pipe) and aligned according to the direction of the airflow.
A depth scale engraved on the probe tube, a flow alignment arrow and an
aligning device will be of help for you.
Once the sensor has been aligned the adapter sleeve must be tighten with
stipulated torque of 20-30Nm (SW 17).
Attention: Alignment of the sensor must not be modified when tightening the connection thread and
adapter sleeve. In this case, please check the immersion depth and alignment again and
correct it if necessary. The angular deviation should not be greater than 2° in relation to
ideal position as otherwise the measuring accuracy will decrease.

9.2 Error messages
Low Voltage
If the supply voltage is less than 11V, the warning message „Low Voltage“ is displayed.
This means that the sensor can no longer work / measure correctly and thus there are none
measured values for flow, consumption and speed are available.
Heater Error
The error message „Heater Error“ occurs in case of failure of the heating sensor.
Internal Error
In the case of this message „Internal Error“, the sensor has an internal read error on e.g. EEProm, AD
converter etc. detected.I
Temp out of Range
At media temperatures outside the specified temperature range, the status message „Temp out of
Range“ occurs.
This temperature overshoot leads to incorrect measurement values (outside the sensor specification).
Low Voltage 4-20mA
For sensors with a galvanically isolated 4-20mA output, a min. Supply voltage of 17.5V is required. If this
value is undershot, the error message „Low Voltage 4-20mA“ is displayed.

Maitenance / Warranty
VA 500 English V1.16 Seite 48 von 52
10 Maintenance
The sensor head should be checked regularly for dirt and cleaned if necessary. Should dirt, dust or oil
accumulate on the sensor element, a deviation will occur in the measuring value. An annual check is
recommended. Should the compressed air be heavily soiled this interval must be shortened.
11 Cleaning of the sensor head
The sensor head can be cleaned by carefully moving it back and forth in warm water with a small
amount of washing-up liquid. Avoid physical intervention on the sensor (e.g. using a sponge or brush).
If soiling cannot be removed, the manufacturer must carry out service and maintenance.
12 Re-Calibration
If no customer specifications are given then we recommend carrying out calibration every 12 months.
For this purpose, the sensor must be sent to the manufacturer.
13 Spare parts and repair
For reasons of measuring accuracy spare parts are not available.
If parts are faulty, they must be sent to the supplier for repair.
If the measuring device is used in important company installations, we recommend keeping a spare
measuring system ready.
14 Calibration
According to DIN ISO certification of the measuring instruments we recommend to calibrate and if
applicable to adjust the instruments regularly from the manufacturer. The calibration intervals should
comply with your internal specification. According to DIN ISO we recommend a calibration interval of
one year for the instrument VA 500.
On request and additional payment, calibration-certificates could be issued.
The precision is given due to use DKD-certified flow meters and verifiable
15 Warranty
If you have reason for complaint, we will of course repair any faults free of charge if it can be proven
that they are manufacturing faults. The fault should be reported immediately after it has been found
and within the warranty time guaranteed by us. Excluded from this warranty is damage caused by
improper use and non-adherence to the instruction manual.
The warranty is also cancelled once the instrument has been opened - as far as this has not been
mentioned in the instruction manual for maintenance purposes - or if the serial number in the
instrument has been changed, damaged or removed.
The warranty time for the VA 500 is 12 months. If no other definitions are given the accessory parts
have a warranty time of 6 months. Warranty services do not extend the warranty time.
If in addition to the warranty service necessary repairs, adjustments or similar are carried out the
warranty services are free of charge but there is a charge for other services such as transport and
packaging costs. Other claims, especially those for damage occurring outside the instrument, are not
included unless responsibility is legally binding.
After sales service after the warranty time has elapsed
We are of course there for you even after the warranty time has elapsed. In case of malfunctions,
please send us the instrument with a short-form description of the fault. Please do not forget to
indicate your telephone number so that we can call you in case of any questions.
