Flow Meter FC01-LQ

6 Parameter selection (menu option: PARAMETERS)

After configuration of the FC01-LQ in conformance with its application (configuration menu), it is possible to set parameters (e.g. limit values).

During parameter setting, measuring operations are not possible (see Appendix 1).

The following parameters may be set in the Parameter selection menu:

6.1 Measuring time (menu option: MEAS. TIME)

The measuring time may be set between 1 and 30 sec., referring both to flow rate and medium temperature.

The effect of the measuring time may be compared to that of a filter; it is used to determine the average of the last measured values (measuring time 100 ms) after each measurement.

The set measuring time does not influence the measuring rate and display up-date.

6.2Limit switch 1 - switch-on value (menu option: LS1 ON = ......)

Limit switch 1 - switch-off value (menu option: LS1 OFF = ......)

Depending on the configuration (see configuration menu) limit value 1 may be set either for flow rate or medium temperature.

The limit value may be set over the entire measuring range and is always related to the display value.

Limit switch up-date is by measuring rate, independent of the set measuring time.

The hysteresis is determined by entering different switch-on and switch-off values. Its magnitude should be reasonably adjusted to current operating conditions.

A specific definition of the operation (closed-current or open-circuit principle) may be dropped by separately entering the switch-on and switch-off value of the limit switch, because the definition is deducted from the switch-on and switch-off value..
