Windows to setup the frequency range (lower and upper limit) for the frequency output
function. Valid range is 0Hz-9999Hz. Factory default value is 0-1000 Hz.
Please remember to order the module if you need frequency output function.
For Version-15 flow meter, you need to indicate on your orders that you need the
frequency function; Otherwise you will get a flow meter which has no frequency output
circuits.
