American Meter Gas Meter Pulser
IMAC Systems now offers a new easy-to-install pulse output retrofit to replace the discontinued Honeywell American Meter RVP-FI gas meter pulse output. The pulser accommodates diaphragm gas meters, including the AC-250, AC-250NX, AM-250, AT-210, AL-425, AC-630, and AC-800.
IMAC Type I Pulse Retrofit Replaces RVP-FI
“Type” Series of Pulsers
The “Type” series of pulsers have similar attributes to the IMAC Pulsimatic. The Pulsers are driven directly by the meter and actuate the meter’s index. Its “wafer” design removes the index from the equation and creates a reliable product because if the index fails, the pulser will continue to pulse. The “Type” series is sleek with a low-profile design. The torque from the pulser is minimal (no gearing).
The “Type” series of pulsers utilize a 2-wire (Form A mechanical reed switch). The pulsers include a label that clarifies to the customer an expected pulse rate. The “type” series of pulsers also includes mounting hardware and tamper seals. The assembly is both robust and reliable. The body of the pulser is a machined (and anodized) aluminum housing.
Pulser Type I and Type I-A
Pulsers are available as Type I or “Type I-A. Type I generates two pulses per revolution of the meter’s drive dog, commonly used on 2’ drive meters. This setup will give the customer one pulse /ft.3 of gas that passes thru the meter. The Type I-A generates one pulse every revolution of the meter’s drive dog, commonly used on 1’ drive meters and metric meters. In a 1’ drive meter, the output ratio is one pulse/ft.3. It pulses by a hub rotating with magnets; these magnets actuate a Form A reed switch.
The Type I pulser is easily repairable if there is a failure from a lightning strike.
