The results of experienced operational testingof converters hydrostatic pressure Sapphire-22-MP-VN-DG applied for measurement of mass flow corrosion inhibitor
The article considers the results of experienced operational tests before and after theconstructive developments converters hydrostatic pressure Sapphire-22-MP-VN-DG installed on the tanks filling installations which are used for the measurement of mass flow corrosion inhibitor supplied in oilfield equipment.  Materials and methods  Reagent used in filling plants Almetievsk oil and gas production OJSC «Tatneft» corrosion inhibitor. Volumetric-mass method for DH-781,method using hydrostatic pressure transducer described in [2].  Results  According to the results of experienced operational tests established that thetransmitter of the hydrostatic pressure Sapphire-22-MP-VN-DG measures the mass flow in reagent reservoirs filling installations with a relativeerror, not exceeding a value of ±0.1%.  Сonclusions  Hydrostatic pressure transmitters Sapphire-22-MP-VN-DG with a limit of permissible basic error ±0.15% of full scale, produced by OJSC Teplokontrol may be used for continuous measurement and monitoring of the mass of the reagent and oil products, and also for use output parameters to control technological processes.
