1. Overview of Wedge Flow Meter

Its detection component is a V-shaped wedge block (also known as a wedge-shaped throttling element), with its smooth top angle facing downwards, which is conducive to the smooth passage of liquids or viscous liquids containing suspended high cherry finger particles, without causing stagnation on the upstream side of the throttling element. Therefore, it is particularly suitable for use in industries such as petroleum and chemical for measuring volumetric and mass flow rates.

2. What is a rectangular differential pressure flowmeter? Simply put, a rectangular flowmeter is a combination of a wedge flowmeter and a Venturi flowmeter. It is a differential pressure flowmeter. The throttling element inserted into the wedge-shaped flowmeter is triangular, while the throttling element inserted into the rectangular flowmeter is rectangular. After inserting the rectangular throttling element, the state of fluid passing through is similar to that of an eccentric Venturi tube. The characteristic is Brother Qi: it is not only suitable for circular pipelines, but also applicable to rectangular pipelines; The advantages of measuring mixed liquids containing solid particles with eccentric Venturi and wedge characteristics; Manufacturing is much simpler and cheaper than eccentric Venturi; The throttling element is not like a wedge-shaped flowmeter, as it does not face the scouring surface of the slag flow and is wear-resistant.

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 upst Principle of wedge-shaped flowmeter

ream 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 relationships. 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 throt
