General Monitors, Lake Forest, CA, offers an integrated ultrasonic gas leak detection system that couples the company's Gassonic gas leak detectors with its MC600 six-channel modular controller. The leak detectors respond to the ultrasonic noise generated by escaping gas at pressures of 145 psi min. for max. coverage of 5–20 m radius and use a SS microphone to measure the sound pressure level (SPL) in the ultrasonic range; integrated acoustic self-test periodically verifies the sensor's operation. The controller connects with up to 6 Gassonic detectors and displays the SPL as well as alarm, warning, and time-delay settings for each device. Applications include process safety monitoring for oil and gas production, refining, storage facilities, compressor stations, and distribution facilities.
