1. Measurement principle of wedge-shaped flowmeter

When a fluid passes through a wedge-shaped flowmeter, due to the throttling effect of the wedge block, a differential pressure equal to the square of the flow rate is generated on the upstream and downstream sides. This differential pressure is led out from the pressure taps on both sides of the wedge block and sent to the differential pressure transmitter for conversion into an electrical signal output. After being calculated by a dedicated intelligent flow integrator, the flow rate value can be obtained. The flow equation of a wedge-shaped flowmeter is C επ D2 2 Δ Pqv=m1-m2 4 ρ, where qv represents fluid flow rate and m3/sC represents outflow coefficient; ε - swelling coefficient of expandable bonds; π D2m - the ratio of open hole to pipe surface turbulence, S1/-4S1- bow shaped flow area, m2D - pipe inner diameter, m; Δ P - differential pressure, Pa ρ - measured medium density, kg/m3

2. What are the well-known manufacturers in China that are good at making wedge-shaped flow meters? Just like orifice plates and V-cone flow meters, there is really no well-known manufacturer for wedge flow meters. Wedge shape is mainly used to measure the flow rate of high viscosity media based on the principle of differential pressure. Generally, the processing accuracy of bulk potatoes is guaranteed, and using a well-known brand of differential pressure transmitter can achieve better measurement accuracy. I have seen successful application cases in a sugar factory, and the use effect is good. The product is from Shandong Yiyi Instrument Company.

3. What are the well-known manufacturers in China that are good at making wedge-shaped flow meters? Wedge flow meters are similar to orifice plates and V-cone flow meters, and there are no well-known manufacturers in the market. This type of flowmeter mainly relies on the principle of differential pressure to measure the flow rate of high viscosity media, so the key is to ensure the machining accuracy of the generator. Usually, choosing a well-known brand of differential pressure transmitter can achieve good measurement accuracy. In practical application, I once saw a successful case of wedge-shaped flowmeter in a sugar factory, and its usage effect was quite good. This product is produced by an instrument company in Shandong. The measurement accuracy of a wedge flowmeter largely depends on the performance of the differential pressure transmitter and the machining accuracy of the generator. Therefore, although there are no well-known manufacturers in the market, accurate traffic measurement can still be achieved by selecting high-quality branded products. For situations where high viscosity media flow needs to be measured, a wedge flowmeter is a good choice. Although there is no particularly well-known manufacturer, as long as the appropriate differential pressure transmitter is selected and the machining accuracy of the generator is ensured, good measurement results can still be achieved. It is worth noting that differential pressure transmitters of different brands and models have differences in accuracy and stability, so when selecting, it is necessary to consider the specific application requirements comprehensively. In addition, the machining accuracy of the object is also an important factor affecting the measurement accuracy. Therefore, in practical applications, it is necessary to ensure that the machining accuracy of the objec
