SignalFire launches AirQ Scout for wireless methane emissions monitoring

SignalFire has launched AirQ Scout—a new methane emissions monitoring device designed for harsh environments utilizing a 900 MHz wireless platform.

SignalFire noted that AirQ Scout is designed to work seamlessly with its 900 MHz gateway, and features MEMS (Micro-Electro-Mechanical Systems) technology for accurate and reliable methane detection—without the need for external power. The first version of the AirQ Scout will be equipped with an advanced methane sensor capable of detecting and measuring methane concentrations between 50 ppm to 1,000,000 ppm. A future version will be equipped with sensors for other gases such as H2S.  Field-tested for reliability, it can detect methane emissions at a rate of 2 SCFH, at distances up to 30 ft. With a communication range of up to 0.5 mi. (800 m), it delivers reliable wide-area coverage, ideal for industrial applications. AirQ Scout offers 15-plus years of sensor life. Its immunity to sensor poisoning and ability to operate in extreme environmental conditions (-40 to 75°C and up to 100% humidity) ensure consistent performance. The sensor performs constant self-testing and reports its operating condition.

Engineered to meet the rigorous demands of hazardous environments, the AirQ Scout is pending Class 1, Division 1 Intrinsically Safe certification and is built to operate safely in hazardous locations without risk of ignition.

To enhance methane detection coverage, especially in areas where wind direction plays a significant role, multiple AirQ Scouts can be strategically deployed to ensure optimal performance. The device offers exceptional stability and accuracy over extended periods without requiring recalibration or correction factors.

The device combines the latest in MEMS (Micro-Electro-Mechanical Systems) technology with long range 900MHz connectivity to set a new standard in greenhouse gas and air quality monitoring. It helps with QUAD 0 “0000” compliance and unsafe condition monitoring. Designed for remote and rugged environments, it operates by MEMS technology without the need for external power, thanks to SignalFire’s integrated 72A/h battery pack—capable of powering the device for up to three years depending on sensing mode. The transmitted measurements include: PPM, LEL, ambient temperature, atmospheric pressure, relative humidity and absolute humidity.

Users can monitor the AirQ Scout in their existing on-premises SCADA systems. They can also monitor the AirQ Scout measurements through the SignalFire Cloud when paired with the RANGER900, offering flexible, real-time data, enabling fast monitoring, alarming and reporting.

Looking ahead, SignalFire plans to introduce additional gas sensors to complement the AirQ Scout such as H2S and flammables.
