This factor is used for filtering the signal coming from the sensor circuitry before it is further processed.

It filters according the following formula:

filter) exp. Sensor(1filter exp. SensorxY

−•+•=

For EL-FLOW types of instruments it will be the “slow” (not differentiated), non-linearized sensor signal. Only in case of a

noisy sensor signal this value will have another value than 1.0. Advise: do not give a value much lower than 0.8, otherwise it

would slow down sensor response too much. Best setting: 1.0.

For (mini) CORI-FLOW instruments it will influence the amount of averaging of the “bare” values. The smaller this value

gets, the slower a (mini) CORI-FLOW instrument will get a sensor signal, but less noise will be on the signal.

This filter is in the control loop so it affects the response time.
