Fig. 12-1 Determination of reference level under operating conditions
Flow velocity sensors with pressure measurement sensor (Type KP) must be
uninstalled as soon as the pressure level measurement fails. The sensor shall
be soaked for an appropriate period and the pressure channel (see Fig. 5-1)
shall be flushed carefully of shall be cleaned with a soft brush.
Do not use high pressure to flush the channel. This may lead to misadjustment
of the 0-point or may even destroy the built-in pressure sensor.
Furthermore never remove the ground plate (risk of leakage or sensor destruc-
tion)!
12.3 Verification of external Level Measurement
Using an external level measurement (e.g. NivuMaster) needs to measure the
filling level in the channel with a yardstick (see Fig. 12-1) and to adjust the zero
point on the level transmitter if required.
Then compare output signal as well as measurement span of the external
measurement with the analog input signal and the measurement span of the
OCM F in PAR menu as well as in I/O menu and adjust accordingly if required.
