Rosemount™ 702 Discrete Transmitter for Plunger Arrival Detection
The Rosemount 702 for plunger arrival was created to be used in natural gas well pads that use plungers to help with well efficiency.
The transmitter is used in combination with an existing plunger arrival sensor to detect the arrival event and send the signal back wirelessly. It was designed specifically to be compatible with the ETC Cyclops Plunger Arrival Sensor model ET-11000.
