Key Concepts and Applications:
Pressure differential measurement, often referred to as differential pressure measurement, is the process of measuring the difference in pressure between two points in a system. This is commonly used in various applications, including fluid flow measurement, filter monitoring, and level measurement in tanks.
Example Application: Flow Measurement:
In flow measurement, a differential pressure device like an orifice plate is installed in a pipeline. As the fluid flows through the orifice, a pressure drop occurs due to the restriction. The differential pressure sensor measures this drop, and the flow rate (Q) can be calculated using the Bernoulli equation and flow coefficients.
Summary:
Differential pressure measurement is a versatile and widely used method for monitoring and controlling various industrial processes. Understanding the principles, types of sensors, and applications can help in selecting the appropriate technology and ensuring accurate measurements.
