FIELD: oil and gas industries.
SUBSTANCE: invention can be used for metering flow rate of gas transported along pipelines. Proposed restriction device contains housing with holes to tap gas pressure and central hole. Housing is provided with slot whose upper part is made closed. Open part of slot is arranged in lower part of housing. Holder carrying diaphragm with calibrated hole is installed in slot. Diaphragm is secured in holder by U-shaped seal fitted on diaphragm. Housing is closed from bottom by cover clamped by strap. Detachable mechanism installed in lower part of housing makes it possible to take out holder with diaphragm.
EFFECT: improved accuracy of metering of gas flow rate, reduced metal usage and increased strength of device.
