MEASURING SYSTEM FOR GAS ACCEPTANCE, SUPPLIED TO AGFCS Russian patent published in 2017 - IPC G01F1/66 

FIELD: measuring equipment.

SUBSTANCE: invention can be used, for example, to measure the volumetric flow and volume of gas at the inlet of automobile gas filled compressor stations (AGFCS) under operating conditions and calculation of the consumed volume of gas reduced to standard conditions. The essence of the invention consists in the fact that in the measuring system for taking into account the gas supplied to the AGFCS, which is capable of accounting for bi-directional flows and consisting of interconnected measuring and recording units, the measuring unit consists of an ultrasonic flowmeter and pressure and temperature converters. Ultrasonic flow meter is made of interconnected electronic unit with a flow rate calculator and an ultrasonic flow transducer, the housing of which comprises a measuring tube with holes in the places of installation of ultrasonic transceivers, and at least four pairs of ultrasonic transceivers disposed at an angle to the direction of flow, with the possibility of forming at least four measuring beams, and the pressure and temperature transducers connected to an electronic unit of flowmeter.

EFFECT: increasing the dynamic range and increasing the accuracy of measurements of the gas volume flow, increasing the rate of production of the resulting volume of gas delivered at the automotive gas filling compressor stations, and the radius of the registration unit's location.
