10 liters/pulse, reed switch for DN15
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.
