The Opetation Description Of The Two Reed Switches System
Please see the diagram of the two reed switches system below, the two reed switches would 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 attacks
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 prevents the loss or overcounting of the signal output due to the switches joggling or the pipe vibrating, so assures the reliability of the signal output.
Warranty
All meters will be guaranteed against defects in workmanship and material for a period of one(1) year from the date of acceptance. Defective meters or parts discovered within this period shall be replaced without charge upon return to the S.H.Meters.
