The Model M60 is designed to monitor PPM and percent level O2 concentrations in natural gas applications. An electro-chemical O2 sensor is incorporated into the design of the instrument. The M60 can be included as an additional measurement with other Envent analyzers, or can be offered as a stand-alone analyzer with an integrated sample conditioning system.
- Electro-chemical sensor
- Dual alarm outputs
- Low power consumption
- Two Line LCD Display
- 4 to 20 mA output
- RS-232 and RS-485 configurable Modbus communications
Oxygen in natural gas gathering pipelines sometimes need to be monitored to ensure streams do not exceed maximum allowed concentrations of oxygen. Common ranges are from 0 to 2,000 ppm and 0 to 25%. Vapour recovery systems where inlet compression pressures are sub-atmospheric, are susceptible to air infiltration and oxygen concentration monitoring serves as an early warning. Storage tank blanket gas and other head space applications frequently require oxygen monitoring for safety reasons.
The M60 offers industry leading value for Class 1, Division 1 Groups C & D hazardous locations.
