1.Application and features
LGU - H annular orifice throttling device is suitable for saturated steam, compressed air, cooling water, gas, burning furnace flue gas, heavy oil, residual oil and condensate, corrosive chemical solution, dirt medium which containing dust particles and other medium measuring. In addition to the advantages of the standard orifice plate, simple structure, easy installation and use. This annular type also have other highlight: no long straight pipe, outflow coefficient stability, can work at bad conditions.
(1) Good for saturated steam, superheated steam, and gas and cooling water such dirt medium. LGU-H annular orifice plate device special structure, make it not easy to jam, even the measured fluid impurities, will not affect the normal work, which increases the measuring accuracy and working reliability.
(2) Suitable for high temperature, high pressure medium flow measurement.
(3) Work more reliable and higher accuracy than segmental orifice plate, eccentric orifice plate.
(4) The equalizing ring chamber structure, greatly reduced the measurement error.
