WIM Compas Flex is an online analyzer developed by Hobre Instruments to continuously measure the Wobbe index of natural gas. The Wobbe index shows a gas's energy delivery capacity at the burner and is a critical parameter for fuel quality control in gas turbines, boilers and heating systems. Analysis follows a continuous measurement principle based on combusting the sample gas within a short time.

The standard version is designed for applications with a sample pressure of 1.5 – 5.0 barg, is wall-mounted and provides two analog Wobbe index outputs. For zero hydrocarbon emission operation, the maximum back pressure is 0.5 barg. Options such as an Ex version, communication protocol, specific gravity meter, sample pressure/flow monitoring and fast loop are added by order code.

WIM Compas Flex features
