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 opening 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. Measurement principle of wedge-shaped flowmeter

When the fluid passes through the beam dynamic wedge-shaped flowmeter, the wedge-shaped structure plays a key throttling role. This throttling process results in a pressure difference on the upstream and downstream sides of the flowmeter that has a square relationship with the actual flow rate. This pressure difference is cleverly introduced from the pressure taps on both sides. These differential pressure signals are then sent to the differential pressure transmitter, which converts them into electrical signals for output. Furthermore, these electrical signals are processed and calculated by specially designed intelligent flow integrators, and ultimately, we can obtain flow values from these tedious mathematical rel

ationships. The flow calculation formula of a wedge flowmeter is based on the following formula: qv=C * ε * π * D ^ 2 * (2 * Δ P)/(1-m ^ 2/4 * ρ), where qv represents the flow rate of the fluid, measured in cubic meters per second (m3/s). The outflow coefficient C and the expansion coefficient ε are important parameters that affect flow rate. The ratio m (S1/D) of the opening area of the pressure port to the inner diameter of the pipeline can also affect the measurement results. Δ P represents the pressure difference, measured in pascals (Pa), while ρ represents the density of the measured medium, measured in kilograms per cubic meter (kg/m3). This formula reflects how flow meters convert pressure changes into actual flow values through physical phenomena and mathematical models. The extended data wedge flowmeter is a new type of flowmeter that began to gradually move towards practicality in the 1980s. Its detection component is a V-shaped wedge block (also known as a wedge throttling component), with its smooth top angle facing downwards, which is conducive to the smooth passage of liquids or viscous liquids containing suspended particles, without causing stagnation on the upstream side of the throttling component. Therefore, it is particularly suitable for measuring volumetric and mass flow rates in industries such as petroleum and chemical.

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 e
