McCrometer - Water Specialities Interfacing
There are the 2 options for getting pulses from the Water Specialities meters:
FC101-XX-K, ( ~$662) "Flowcom". More difficult to install. Meter must be removed from the pipe to convert from mechanical to digital. This includes replacing the prop, removing the miter gear frame assembly and vertical shaft. Will be replacing with a magnetic pickup sensor and digital head.
7-TR12-2-R, ( ~$836). Easier to install: remove old register and install new register with TR12 transmitter included. Pulse output is 1 pulse per totalizer multiplier. Has a reed switch output, see datasheet below.
