DDTOP LGY Compact Orifice Plate Flow Meter

Description of DDTOP LGY Compact

LGY compact orifice plate flow meter consists of a flow element, a differential pressure transmitter, a manifold, a temperature sensor and a pressure sensor, and can measure various medium such as liquid, gas, and vapor. The flow element implements the standard of GB/T2624-93 “Flow Measurement Flow Element Uses Orifice Plate, Nozzle and Venturi Tube to Measure the Flow of Fluid Filled with Circular Pipe” , adopting LG-94-01win “Flow Element Design Calculation And Management Software”design calculation, according to JJG640-1994 “Differential Pressure Flow meter Verification Regulations” and JB4730-94 “Pressure Vessel Non-destructive Test”, and verify the actual measurement accuracy through the flow standard device inspection.

Structure Type
LGY compact orifice plate flow meter has two main structure forms: one is simple integration, which is to assemble the orifice plate, manifold, and differential transmitter together. This structure is used in situations where temperature and pressure are relatively stable; the other is compensation integration. It is to assemble the orifice plate, the manifold, and the differential transmitter together, and increase the temperature and pressure compensation function. This product has high measurement accuracy and is suitable for occasions that require precise measurement.
LGY compact orifice plate flow meter has compact structure and simple installation, which can save a lot of installation work for users; assembled in the factory to ensure stable and consistent measurement accuracy, the consumption of LGY compact orifice plate flow meter has increased significantly in recent years, and the common specifications are concentrated below DN150.
