ERROR MESSAGES
In case the flowmeter is equipped with the optional display, the following error message can be indicated.
ERROR 01: sensing probe is not detected
Cause:
the sensing probe is not connect or is defect
Effect:
the display indicates “0” for all measurand. The analogue output defaults to the lowest
configured value.
Action:
check the head of the sensing probe for visual damage.
check the sensor cable from the sensing probe to the electronics of the signal conditioning.
ERROR 02: the EEprom is defect
Cause:
the EEPROM for the storing of the consumption counter and MIN /MAX value is defect.
Effect:
the consumption counter and MIN / MAX values are no longer available. All measure-
ment values though are still indicated. The analogue, relay and pulse output are still
functional.
Action:
return the flowmeter to the manufacturer.

MAINTENANCE
Regular cleaning of the sensor is necessary is used in applications with wet or filthy gases. Cleaning of the
sensor is necessary prior to calibration or evaluation.
7.1. Cleaning of the sensor of the flowmeter
Do not use an abrasive cleaning agent, an organic solvent containing halogen or acetone.
•
Clean the head of the sensor probe by carefully swirling in warm water of isopropyl alcohol. It is
recommended to use isopropyl alcohol if the pollution is crease or oil.
The sensor should not be touch by fingers or solid objects like screwdrivers or brushes!
•
Leave the sensor to dry in ambient air.
