Holes on the balancing plate of the porous balance flow meter

A multi-hole balance flow meter is a device used to measure gas or liquid flow. Its basic principle is to restrict the passage of fluid through one or more holes in order to measure flow. The balance piece is one of the key components of the porous balance flowmeter. It has many small holes on it to restrict the flow of fluid. Here's how the holes in the balance sheet work:

Number and Size of Holes: The holes in the balance sheet usually come in different numbers and sizes, and the size and number of these holes can be adjusted according to the needs of a particular application. These holes are usually evenly distributed on the surface of the balance plate.

Pressure drop measurement: The hole in the balance plate restricts the flow of fluid, thereby creating a pressure drop between the upstream and downstream of the hole. By measuring this pressure drop, the velocity and flow rate of the fluid can be determined. Generally, a larger pressure drop indicates a higher flow rate, while a smaller pressure drop indicates a lower flow rate.

Accuracy and sensitivity: The number and size of holes in the balance plate will affect the accuracy and sensitivity of the flow meter. More small holes can increase sensitivity, but may reduce the ability to measure maximum flow. Conversely, fewer large holes may increase the maximum flow measurement capability but may reduce the sensitivity of the flowmeter.

In general, the holes in the balance sheet restrict the flow of fluid, allowing the porous balance flowmeter to accurately measure the flow of fluid. Different applications require different numbers and sizes of orifices to meet their specific flow measurement requirements. By measuring the pressure drop, the flow rate and flow rate of the fluid can be calculated, thereby achieving the purpose of flow measurement.
