EspañaOrifice plate flowmeters measure fluid flow based on the pressure differential created by fluid passing through an orifice plate. It consists of an annular metal plate (called an orifice) with a standard aperture. When the fluid passes through the orifice, a local constriction is formed, resulting in a drop in pressure. According to the Bernoulli equation and the correction coefficient, the pressure difference is proportional to the fluid velocity. By measuring the differential pressure, the flow rate of the fluid can be accurately calculated.
1. High precision: Orifice plate flowmeter has precise measurement capability, and its error range is usually within ±1%, which is suitable for long-term stable flow measurement.
2. Easy to install and maintain: The device has a simple structure, is easy to install and disassemble, and has low maintenance costs.
3. High reliability: Orifice plate flowmeter is not affected by fluid properties and working environment, and can be applied to various fluids, such as liquid, gas and steam.
4. Low cost: Compared with other flow measuring instruments, Orifice plate flowmeter is relatively cheap and suitable for various budgets.
Orifice plate flowmeter is widely used in various industries, such as chemical industry, petrochemical industry, electric power, metallurgy, food and beverage, etc. It can be used to measure the flow of liquid, gas and steam, and is suitable for pipe diameters ranging from small to large. In the chemical industry, it is often used to detect the medium produced by chemical industry to monitor the production process. In the field of petrochemical industry, it is used to measure the flow of crude oil to achieve accurate metering. In the power industry, it can be used to monitor the flow of cooling water or steam to ensure the normal operation of equipment. In the food and beverage industry, it can be used for process control and metering to ensure that products meet standards.
