Optic Fiber Telescopic Gasometer Gauge of GM series is a new model of high precise gasometer gauge welcomed by the market since The various telescopic gasometer gauges currently used are of low precision and poor reliability in detecting and transferring the field electric signals. Hidden hazard and unobserved unsafely factors always lurk around.

A reliable safe and accurate means are strongly required to perform the automatic and continuous tracing and measuring of the operation of gas cabinet in the field of coal gas gathering and management in the industries of metallurgy and energy, wherethe wet and dry monitoring and metering of coal gas cabinet are developing on the way of detection automaticity.

This Optic Fiber Telescopic Gasometer Gauge of GM series is developed jointly by WISCO and Wuhan University of Technology. It is a successful industrial application sample of optical fiber sensing technique. It was granted accreditation by the Scientific Committee of Hubei Province in Nov.1995 as rated on the internationally advanced level. With high precision, sensitivity and reliability, it can display the momentary conditions of the gas cabinet while the gas coming in and out or its static condition. It can automatically and continuously perform a long-lasting all-weather on-line detection.Dispensing with on-site power supply eliminates unsafe factors. It is mostly suitable under explosive and flammable circumstance like the wet or dry coal gas cabinet measurement in the field of fuel gas energy. This product has achieved a perfect success on all its installations in the coal gas cabinets in WISCO. It sufficesconsummately all requirements for the automatic management of coal gas cabinet reserves.
