Limit flow orifice plate flowmeter utilizes the orifice plate to generate pressure drop to measure the fluid flow, which can limit the flow or reduce the pressure. Its structure is simple, low cost, easy to install, and has temperature and pressure automatic compensation function. Widely used in industry, environmental protection, petroleum and other fields, is an effective tool for measuring and limiting fluid flow.
Project Overview
The restriction orifice flow meter is a special flow meter, mainly used to limit the flow of fluids or reduce the pressure of fluids. It is based on the working principle of the orifice plate flowmeter, that is, when the fluid passes through the orifice plate, the holes on the orifice plate will produce a certain resistance. This resistance will affect the flow of the fluid, thereby causing the pressure inside the flow meter to change, so that it can Measure the flow of fluid.
The specific working principle of the restricted orifice plate flow meter is that when the fluid passes through the orifice plate, a pressure drop will occur, and the flow rate through the orifice plate increases as the pressure drop increases. But when the pressure drop exceeds a certain value, that is, exceeds the critical pressure drop, no matter how the outlet pressure decreases, the flow rate will maintain a certain value and will no longer increase. The flow-restricting orifice plate is used to limit the flow of fluid or reduce the pressure of the fluid based on this principle.
The advantages of the restricted orifice flow meter include simple structure, easy processing, low manufacturing cost, and easy installation. On the premise of meeting process requirements, using a flow-limiting orifice plate instead of a regulating valve to limit flow or reduce pressure can greatly reduce investment and operation and maintenance costs. In addition, the flow-limiting orifice flowmeter also has the function of automatic temperature and pressure compensation. It is powerful in function, compact in structure, simple to operate and easy to use.
Restricted orifice flow meters have a wide range of application scenarios, including but not limited to industrial fields, tap water and sewage treatment, environmental protection, oil and natural gas, cooling water, food and beverages and other fields. When it is necessary to measure the fluid flow in a pipeline, especially when it is necessary to limit the flow or reduce the fluid pressure, the restriction orifice flow meter is an effective solution.
