1、 Overview:
The ARSV insertion V-cone flowmeter is a differential pressure flowmeter proposed in the 1980s. The ARSV insertion V-cone flowmeter is still a throttling device that reflects the flow rate by throttling the differential pressure. The throttling element is a conical body suspended in the center of the pipeline, and the high pressure P1 is taken from the pipe wall in front of the cone where the fluid is not disturbed (i.e. no throttling is formed and the fluid is not accelerated); Low pressure P2 is taken from the center of the rear cone and is introduced to the outside of the pipe through a pressure pipe. The square root of its differential pressure △ P is proportional to the flow rate. Calculations are similar to orifice plates, nozzles, etc.
