IMAC Pulse Output Device for Dresser Rotary Meter

 In Pulsers

IMAC Systems now offers the Pulser TYPE IV, a new easy-to-install and simple pulse output devise for Roots Dresser rotary gas meters B3 (Series 3) product family. The pulse retrofit uses the meter’s drive to create a pulse, and the pulses are proportional to the gas volume passing through the meter.

Roots Dresser Meter Pulse Output

The IMAC Systems TYPE IV pulser adds a pulse to a CTR or TC-CTR Dresser meter. The pulser comes installed on a premounted Dresser module so the user can remove the old Lexan globe from the meter and install the premounted Type IV (or IV-A) Lexan globe. Installation is quick, generally under five minutes, and can occur while the meter is under pressure.

IMAC Pulser TYPE IV and IV-A

The Pulser TYPE IV utilizes the IMAC TYPE I pulser affixed to the Dresser OEM AMR adapter kit. When installed onto the meter, TYPE IV uses a 2-wire (“Form A” mechanical reed switch). The pulsers include a label illustrating the expected pulse rate. The torque from the pulser is minimal (no gearing), and it is easily repairable if there is a failure, for example, in a lightning strike. The assembly is robust and reliable, and the body of the pulser is a machined (and anodized) aluminum housing.

The pulser is available as a “Type IV” or “Type IV-A.” Type IV generates one pulse per revolution of the meter’s drive dog, commonly used on NTC and TC meters. The Type IV-A generates ten pulses per revolution of the meter’s drive dog, widely used if a higher frequency pulse output is required.

When using a CD or TD Dresser Meter (instrument drive), use a Pulsimatic Transmitter. If you have an older Dresser LMMA meter (Seres 1), message us to learn about IMAC’s solution for that product.
