2.2 measuring principle
The remote controller 8032 must be connected to a remote flow rate
measuring element with an NPN transistor output or a push-pull output�
The controller 8032 detects the pulses sent by the remote measuring de-
vice� The pulse frequency is proportional to the flow rate (f = K�Q, where f
is the frequency in Hz, K the K factor specific to each measuring device in
pulses/l and Q the flow rate in l/s)�
