The flow rate Q is proportional to the input frequency f_(in ), as shown in the fromel below:

For. 1: Flow rate calculation
K-factor KF is unique for each displacement meter. The value of K-factor is determined by means of the mandatory
flow calibration. Only authorized persons may change the K-factor of a KEM displacer meter!
6. Service and Maintenance
6.1. Maintenance
The ECO does not require regular maintenance.
If for the specific application an obligatory calibration is required, refer to the corresponding national regulations
for the necessary calibration intervals. For the best performance we recommend a calibration of current output in
the interval of 5 years.
The calibration can be carried out by ECO-COM.B.USB and the software KEM EcoControl directly from the
customer or in our production.
6.2. Trouble Shooting
In case the ECO does not work properly, first check the following items:
No output signal?
All cables properly connected, as described in chapter 4.1?
Connect the missing cables..
ECO properly mounted , as described in chapter 3.1?
Verify that the installation was performed properly.
Output frequency too low?
Alle No output signal?
All cables properly connected, as described in chapter 4.1?
Check the wiring.
The flow meter ist running?
Check the flow meter! Replace the counter if necessary.
Output frequency too high or unstable?
Most probably EMC problems
Shield and ground properly connected?
Connect shield properly.
If necessary, try additional means of grounding and shielding
