1. The difference between orifice flowmeter and balance flowmeter
Both orifice flowmeter and balance flowmeter belong to differential pressure flowmeter, and their core differences cover four dimensions: principle, structure, performance, and installation. Balance flowmeter has stronger comprehensive adaptability, but orifice flowmeter has lower cost and simpler structure. 1. Principle difference: Both are based on differential pressure measurement logic that generates pressure difference through fluid throttling, relying on Bernoulli equation to calculate flow rate: the orifice flowmeter relies on a single thin plate with a central circular hole to achieve throttling, and a pressure difference is formed on both sides when the fluid flows through the orifice plate; The balanced flow meter adopts a porous symmetrical throttling structure, which allows the fluid to be distributed more evenly before and after throttling, and stably generates a measurable pressure difference. The structure difference of the orifice flowmeter is minimal, consisting only of a thin plate with a central circular hole, a pressure measuring device, and a measuring tube; The structure of a balanced flowmeter is more complicated, with multiple wheel leakage throttling holes distributed in the same plane. The shape, size, and distribution of the holes need to be customized and adjusted according to specific operating conditions. 3. The performance characteristics can be visually compared between the two through a table: | Performance dimension | Orifice flowmeter | Balanced flowmeter | ------- | ------- | | | Pressure loss | Large, which will increase subsequent operating energy costs | Small, can reduce long-term operating costs | Measure
2. Principle of Balanced Flow Meter
A balanced flow meter is a type of differential pressure flow meter, which has been improved in terms of product performance, technology, or appearance. The same principle also has its own advantages and disadvantages, but its working principle is the same as other differential pressure flow meters, which are based on the energy conversion principle in sealed pipelines: in ideal fluid conditions, the flow rate in the pipeline is proportional to the square root of the differential pressure;
; The flow rate in the pipeline can be calculated based on the Bernoulli equation by measuring the differential pressure value. The balanced flow sensor is a porous disc throttling rectifier installed on the cross-section of the pipeline, with eac
