DEVICE FOR MEASUREMENT OF DENSITY OF NATURAL GAS

摘要

Device for measurement of density of natural gas includes pipeline system of gas supply equipped with control apparatuses and means for measurement of gas parameters. Pipeline system of gas supply consists of two testing sections – inlet pipeline of high/medium pressure and pipeline of medium/low pressure. First of those is equipped with control apparatuses that include shutoff valve, filter and pressure controller. The second is equipped with rotor has meter with transformer of rotor revolutions to pulse signals, corrector of volume/volumetric gas flow rate and means for measurement of parameters of pressure and temperature. All measuring means and control apparatuses are connected to electronic information-measuring-control system and together with it are combined in portable cabinet/case. Inlet pipeline of high/medium pressure at inlet and medium/low pressure pipeline at outlet are equipped with fittings for connection of device with flexible hoses to operating pipeline in place of measurement.
