SERVICE INFORMATION
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.
Cleaning of the sensor head
The sensor head can be cleaned by carefully moving it to and fro 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, service and maintenance must be carried
out by the manufacturer.
Re-calibration
If no customer specifications are given then we recommend to carry out calibration every
12 months. For this purpose the sensor must be sent to the manufacturer.
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 to keep a
spare measuring system ready.
Calibration certificates
Calibration certificates are issued by the manufacturer on request. This is a fee-paying
service. Precision is tested with DKD (= German calibration authority) certificated volume
flow meters.
