QINSUN interprets orifice flow meters to measure all single-phase flow –

Author:QINSUN Released in:2023-05 Click:72

The orifice plate flowmeter is a high ratio differential pressure flow device consisting of a standard orifice plate and a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter and temperature transmitter). pressure). Measure gas, steam, liquid and lead flow, widely used in process control and measurement in petroleum, chemical industry, metallurgy, electric power, heating, water supply, etc.

The orifice flow meter can measure all single-phase flow, and some mixed-phase flow can also use this product. Due to two-phase flow, it cannot be measured accurately and even water hammer can occur, which can damage pipe fittings. If an annular orifice plate is used, condensate may drip from the edge of the plate.ue with annular orifice. The small flow area is a ring near the inner wall of the tube, while the small flow area of ​​a standard orifice plate is a concentric circle in the center of the tube.

When the flow of impurities in the fluid is low, it usually flows near the pipe wall, and new varieties of throttling devices continue to appear and have been popularized and applied. The differential pressure transmitter and display matched to the throttling device Instrumentation has evolved rapidly in terms of performance and quality.
