The operation 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 “OFF” in one
round of the pointer or the gear means one signal output, this
principle prevent the loss or over-counting of the signal output
due to the switches jogging or the pipe vibrating, so assures
reliability of the signal output.
Maximum permissible error
