Solid state Pulse Transmitters provide fast and accurate signaling for remote indication, totalizing and data monitoring systems. The unit is mounted directly on the flow meter and is coupled to the meter's output shaft.

Design Features:

• High resolution of 100 pulses per revolution
• Wide operating voltage span
• Very low power requirement
• Low driving torque places minimum load on flow meter shaft
• Wide operating range (within 1000 meters of receiving instrument)
• Flameproof enclosure certified by CMRI, Dhanbad for use in gas group IIA and IIB hazardous areas

Principles of Operation:

The unit consists of a precisely slotted disc, rotating through a solid state optical switch, which houses an infrared light source and a light sensitive diode. The optical switch detects the passage of the slots on the disc, as the input shaft rotates and translates them with the help of an in-built electronic circuit, into positive square wave output pulses. One revolution of the input shaft produces 100 pulses at the output.

Applications:

• Operating remote electronic counters to indicate flow meter throughput
• Operating preset counters to control preset quantities through the flow meter
• Operating flow recording and flow rate indicating instruments
• Data acquisition systems
