The operation description of the two reed switches system
Please see the diagram of the two reed switches system below, the two reed switches woud be operated "ON" OR"OFF" respectively by the magnet fitted to the pointer or gear during its running on the register, but never "ON" at the same time, unless the out- magnet attackes. The two reed switches operate two "ON" and two "OFF" in one round of the pointer or the gear means one signal output, this principle prevent the loss or overcounting of the signal output due to the switches joggling or the pipe vibrating, so assures reliability of the signal output.

Application:
--Measuring the total volume of cold portable water passing through the pipeline.

Feature:
--Multi-jet, dry-dial, easy for maintenance;
--Magnetic drive reliable characteristic, long working life;
--Vacuum sealed register ensures the dial keep free from fog and frost, Keep the reading clear in a long term service;
-- Technical data conform to international standard ISO4064 Class B
---Pulse with 10L/pulse, 100L/pulse, 1000L/pulse
