Understanding SIL, SIS, and SIF: A Detailed Explanation

In the world of safety and automation, understanding the distinctions between SIL (Safety Integrity Level), SIS (Safety Instrumented System), and SIF (Safety Instrumented Function) is crucial. These concepts form the backbone of ensuring industrial safety, particularly in environments like chemical plants, oil refineries, and other high-risk industries. Below is a comprehensive guide to clarify the […]

Notes on turbine flowmeter

The turbine flowmeter is a typical velocity flowmeter. It has the characteristics of high measurement accuracy, fast response and high pressure resistance, so it is increasingly used in industrial production. The turbine flowmeter works based on the principle of conservation of fluid momentum. The measured fluid pushes the turbine blades to rotate the turbine. Within

How to judge whether the differential pressure transmitter is working properly

During the field use of differential pressure transmitters, how do we judge whether their working status is normal? Since most of the faults of differential pressure transmitters are zero drift and blockage of pressure pipes, the scale is rarely calibrated point by point on site, but the zero point and change trend of the differential
