The RM-2000 Coal Bed Methane Special / 777 combination optimizes gas production from coal bed methane wells while protecting the submersible pump. The 777 provides unmatched pump protection while the RM-2000 CBM Special cycles the pump based on pressure measurements from one or two 4-20 mA pressure transducers. A built-in flow meter signal conditioner and RTD signal conditioner provide low cost water output monitoring and blower control features.

The first transducer measures down hole pressure while an optional second transducer can be used to measure annulus pressure (gas pressure). The second transducer corrects head measurements caused by high annulus pressure. The pump is started when the maximum head set point is exceeded and stopped when the minimum head set point is passed. The feet-of-head is displayed in real time with the turn on and turn off head set points. This system is compatible with a wide range of 4-20 mA pressure transducers.

A built in rapid cycle timer prevents over cycling the pump if the water level recovers too quickly. The rapid cycle timer can be used to minimize run cycles or delay pump starts on wells with high annulus pressure when the annulus transducer is not used. A real time display shows the remaining time before the pump can automatically restart.

A RS-485 network communications port allows remote control and monitoring of up to 99 separate wells. PLC, computer and SCADA systems can read current head, raw pressure measurements and the remaining time on the restart delay timer. The restart delay, turn on set point and turn off set point can be adjusted from the network as well.

The RM-2000 CBM Special / 777 combination is a proven, highly reliable system that has many advantages over other gas production systems.
