MEASURING LINE AND METHOD OF MEASUREMENT OF GAS DYNAMIC PARAMETERS Russian patent published in 1997 - IPC

FIELD: gas producing industry, particular, gas dynamic investigations of gas and gas-condensate producing wells. SUBSTANCE: the offered measuring line is installed on working line and equipped with flow meter, temperature and pressure measuring units, sampler, diaphragm union, flange joints and expansion sleeve. Sleeve includes two branch pipes movable inside the body, position retainers and handle. Diaphragm union has body, holder with diaphragm and removable sealing ring, upper and lower removable chambers, studs for chamber fastening, handwheel, lower and upper stop strips. Shutoff valves of inlet chamber are interconnected hydrodynamically. The method of measurement consists in that without stopping gas flow in transition from one stationary mode to some other, after performance of required gas dynamic investigations, diaphragm is replaced. The, next measurements are taken of all gas dynamic parameters after stabilization. EFFECT: higher efficiency. 3 cl, 3 dwg
