Flow instrumentation is used to measure the flow of a fluid within a system or industrial process. Flow can be measured in terms of volume, mass, or velocity of the fluid passing through a specific point in the system. Flow rate plays a crucial role in ensuring the proper functioning of industrial processes, enabling precise fluid flow control and contributing to operational efficiency and regulatory compliance.

Pressure instrumentation is used to measure and monitor the pressure of fluids or gases in various industrial, laboratory, and process settings. This instrumentation is essential for controlling and regulating various parameters within systems and machinery. There are different types of pressure instrumentation, each suited to specific applications and operating conditions.
