NOTE: Connections for measuring the
amount of current flowing in the 4-20 mA
loop. There should be 4.0 mA with no water
flowing through meter and 20.0 mA at full
scale. Connect ammeter in series with circuit.

in the 4-20 mA loop. There should be 4.0 mA with no water flow-
ing through meter and 20.0 mA at full scale. Connect ammeter
in series with circuit. If there is no current in the loop and the
power supply voltage is there, then the problem is possibly in
the communication lines or the transmitter circuit board.
