In-depth Understanding Orifice Plate Flow Meter Instrument: Principles, Features, and Advantages

In industrial production and fluid measurement fields, Orifice Plate Flow Meter as a common and important flow measurement device, the instrument plays a crucial role. With its unique working principle, significant characteristics, and numerous advantages, it provides a reliable solution for accurate flow monitoring in various process flows. Today, let's delve into the mysteries of the orifice plate flow meter and understand its key position in modern industry.

I. Working Principle of Orifice Plate Flow Meter

The working principle of the orifice plate flow meter is based on Bernoulli's equation . When fluid flows through the orifice plate, due to the throttling effect of the orifice plate, a pressure difference will be generated before and after the orifice plate. There is a certain mathematical relationship between this pressure difference and the fluid velocity and flow rate. By measuring the pressure difference before and after the orifice plate and combining the known physical properties of the fluid and the geometric dimensions of the orifice plate, the flow rate of the fluid can be calculated.

Specifically, when the fluid flows in the pipe, it passes through the orifice plate, a local resistance component, and the flow rate increases, while the pressure decreases. According to the law of conservation of energy, the decrease in pressure energy is converted into an increase in kinetic energy. The pressure difference before and after the orifice plate is measured by a differential pressure transmitter and converted into a standard electrical signal output. Then, using the pre-calibrated flow calculation formula, the pressure difference signal is converted into the corresponding flow value.
