Reed Switch: Reed Switch is a 2-wire device which
triggers by magnet inside the rotors as they spin. To
maximise the life of the reed switch, the pulse board
comes equipped with a 1k8Ω current limiting resistor
in series.
Hall Effect Switch: Hall Effect switch is a 3-wire
device which triggers by south pole of the magnet
inside the rotors as they spin. This switch is NPN
type. The switch circuit is equipped with a 4k7Ω pull
-up resistor between signal and supply.

Analogue outputs are available as an auxiliary display signal by including ERA, PRA and PRM with the flow
meter. PRA and ERA display also output scalable pulse.
