It is therefore strongly recommended that min. flow should be set to logical values.
Simply set to 1 will lead to a bad behavior of the measurement.
Max flow is the maximum flow that must be measured correctly.
This value is used to determine the measurement method when Auto is selected as the measure-
ment method.
In order to achieve good accuracies, we recommend the ratio between max. flow and min. flow not
greater than 1:10.
Gate time is only relevant if pulse counter measurement is used.
Gate time specifies the length of the time window in which the occurring pulses are counted.
This also results in the update rate for the flow value.
Higher gate values will increase accuracy, but the flow value will not update as often.
Gate times below 2 times the lowest operating frequency must be avoided, in which case the
measurement results are not reliable.
Debouncing is only relevant for pulse length measurement.
Pulses that are consecutively registered in less time than the set debounce time are considered
just as one impulse.
This prevents the bouncing of the contact from registering more pulses than there are actually pre-
sent.
A value of 10 to 20 ms is sufficient in most cases for mechanical contacts.
For turbines or for electronic contacts, the value to be set may be 0 ms.
