Uses Eltomatic, Denmark make Encoder (CE marked, IP65/NEMA4 certified)
Very low power requirement
PRINCIPLE 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.
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
