Measuring principle of HSP balanced flowmeter

Project Overview

HSP balanced flow meter is a revolutionary differential pressure flow meter. Its working principle is the same as other differential pressure flow meters. It is based on the principle of energy conversion in sealed pipes: in the case of ideal fluid, the pipe The flow rate in is proportional to the square root of the differential pressure; the measured differential pressure value can be used to calculate the flow rate in the pipeline according to Bernoulli's equation.

HSP balanced flow sensor is a porous disc throttling rectifier installed on the cross-section of the pipe. The size and distribution of each hole are customized based on special formulas and test data, called functions hole. When the fluid passes through the function hole of the disk, the fluid will be balanced and rectified, and the vortex will be minimized, forming an approximately ideal fluid. Through the pressure sensing device, a stable differential pressure signal can be obtained, and the volume flow rate, mass flow.

If a flow blocking piece (commonly known as a throttling device) with a flow area smaller than the cross-sectional area of ​​the pipe is fixedly placed in a pipeline filled with fluid, the fluid in the pipeline will locally shrink when passing through the throttling device. The flow area at the contraction becomes smaller, the flow rate increases, and the static pressure decreases. Therefore, a certain differential pressure will be generated before and after the throttling device. The balanced flow sensor also works based on this principle. Not only can it generate a differential pressure, but because the throttling device in the balanced flow sensor is also a rectifier, the differential pressure generated is particularly stable. According to the law of mass conservation and energy conservation in fluid mechanics, the volume flow rate and mass flow rate of the fluid can be calculated.
