Type F9.00, F9.01 and F9.02 Flow Monitors/ Transmitters are designed to process the pulse signals from all FlowX3 Hall Effect flow sensors. All units have a number of control outputs including 4 to 20mA, open collector (pulse) and relays. They have 3 line LCD displays and LED indicators for control output status (see page 23). The instruments supply voltage to the flow sensor. Modular design allows the same instrument to be mounted in three different ways: directly to the flow sensor or remotely either panel or wall mount.
