Flow Indicator Totalizer

Application :

MODEL: SC / R - 1400

Flow Indicator Totalizer model instrument with multi-functionality viz. Flow Rate indication, Flow Totalizing, batch counter & alarm for instantaneous flow. It accepts mA signal proportional to flow rate from flow transmitter. Flow Transmitter can be DPT with orifice assembly, Rotameter, Magnetic Flowmeter etc. with output of 4-20 mA.

FIT displays instantaneous flow rate on 5 digit LED Display. Flow Rate and Totalizer range can be configured as required even at site. Totalizer is a 8 digit LED Display. Totalizer can be reset manually or remotely as optional. The unit incorporates two relays, from which one can be used for alarm for instantaneous flow & one for batch counter or both for alarm. On each set point one contact output is given, which can be used for control or hooter applications. Power Supply for external transmitter (24VDC @ 100mA) is a standard feature. It eliminates need of separate power supply to power the transmitter. For batch counting, batch count can be set. When flow total equals preset count, system gives a contact output. It can be used for control operations like dosing, stoppage etc.
