UF Series ultrasonic flow meter how to set the frequency signal output?

UF Series ultrasonic flow meter / energy meter takes the function of frequency signal output that means using high and low of frequency to show the size of transient flow. Users could reset  the range of frequency signal and the scope of instant traffic according to their practical needs.

  For example: a flow range of 0 ~ 2000M3 / H, corresponding to the frequency requirements of the output signal 100 ~ 1000Hz and can make the following settings:

Press [menu] [6] [7] to enter the lower limit frequency of "100" and maximum frequency "1000"

Press [menu] [6] [8] enter "0 "
