Missing level measurement

Note: Without a working level measurement it is not possible to measure flow
velocities and hence the flow cannot be computed.

Alternative flow velocity determination:

The flow velocity measurement can be verified even if a level measurement is
defective or not even. To do so, the instrument needs to be reprogrammed tem-
porarily.
For the period of verification proceed as follows:

-

set the level sensor to >Fixed value< in menu >PAR\Level\Sensor type<

-

enter a plausible value

-

Observe that the value is higher than the value entered in parameter h_crit

-

Confirm the entries

The OCM Pro CF now operates using the fixed value. This makes sure that the
flow velocity sensor is capable of positioning its measurement windows in differ-
ent levels in order to carry out measurement.

Velocities still do not display?

After all measures described above have been taken, finally proceed as follows:

-

Is the sensor connected correctly?

-

Check the cable routing

-

Check the transmitter clamp terminals for proper connection

-

Check if the overvoltage protection is connected properly

Should all these measures not be successful, return the sensor to the manufac-
turer. The flow velocity sensor might be defective.

In various countries it may be necessary to carry out regular maintenance with
comparative measurements  in particular applications to comply with official reg-
ulations:

-

evidence of compliance with official regulations

-

regular maintenance

-

comparative measurements

Within the scope of a maintenance contract NIVUS offers the services below:

-

regular inspection

-

hydraulic and technical assessment

-

calibration

-

troubleshooting and repairs

These services will be carried out according to DIN 19559 incl. the agreed proof
of the remaining residual error, as well as according to rules in the respective
countries.
