Turbine meters, like all other metering devices, measure natural gas at line conditions. Gas volumes, unlike liquids, vary with changes in temperature and pressure following the well known Boyles and Charles Laws. Base conditions have been defined as an inlet pressure of 4 oz. at a temperature of 60 F. This defines a common set of conditions for gas measurement. Any variance in these parameters require a calculation to correct the gas volume to base conditions. The Electrocorrectors have been designed to fill a recognized market, offering a number of features to challenge the traditional mechanical integrators. Accuracy - Measurement accuracy approaching that of the base volume computers is obtained. Calibration - The Electrocorectors have been designed to provide effortless calibration which can be performed by field personnel in a matter of minutes. No specialized technical training is required. Mounting - The Electrocorectors are installed exactly like a mechanical instrument - no new procedures are required. Fewer precautions are required. Self-Contained - The battery powered Electrocorectors require no additional external connections. Safety - The Electrocorectors are designed to conform to the specifications of intrinsic safety to allow meter mounted convenience.
