Flow meter

1. Working Principle of Vortex Flow Meters: The principle of the vortex flow meter is to place a bluff body in the flow meter pipe. When fluid flows past the bluff body, due to the flow separation at the bluff body’s surface, two alternating vortex streets are generated downstream, known as Karman vortex streets. The […]

Instrument inspection is a critical part of maintenance programs in industries that rely heavily on equipment for production, process control, and safety. Regular inspections ensure that instruments are functioning properly, potential issues are detected early, and the overall efficiency of operations is maintained. This article outlines the essential elements of a detailed instrument inspection procedure

Chemical engineering instrumentation plays a crucial role in monitoring, controlling, and optimizing chemical processes. Mastering chemical instrumentation is essential for anyone pursuing a career in chemical engineering, as these tools ensure process safety, efficiency, and quality. Here’s a detailed guide to help you systematize your learning of chemical engineering instrumentation. 1. Understand Fundamental Theories A.

Temperature and pressure compensation strategies are crucial in ensuring accurate measurements and efficient control in processes involving fluids such as liquids, gases, and steam. Variations in temperature and pressure can significantly alter the physical properties of these fluids, including their density, volume, and pressure, making it essential to apply the right compensation techniques for each

Introduction Residual Fuel Oil (RFO), often referred to as heavy fuel oil, is a byproduct of the crude oil refining process. It is one of the densest and most viscous forms of fuel oil, primarily used in industrial applications such as power generation, marine propulsion, and large-scale heating systems. Due to its high viscosity and

1. Installation Location Importance of Installation Site Selection The installation location of a vortex flowmeter plays a crucial role in ensuring accurate measurements. The device should be positioned in a part of the system where the airflow is steady and not influenced by turbulence caused by bends, valves, or other obstructions. For optimal performance, the

In Distributed Control Systems (DCS), the concept of an alarm deadband (also known as alarm hysteresis or alarm differential) refers to a predefined range around an alarm setpoint where small fluctuations in the measured value do not trigger multiple alarms. This mechanism is essential in preventing alarm systems from constantly sounding due to minor, insignificant

Have you ever compiled your own instrument repair experience? Or is your summary incomplete? Here are 60 important tips to pay attention to during the process of instrument maintenance and repair. Consider this your comprehensive guide! Part 1: General Guidelines and Safety Measures (Tips 1–15) Do not mix signal cables with power supply cables in

In engineering flow measurement, accurate measurement is key to ensuring production safety and efficiency. However, achieving high-precision measurements under varying operating conditions remains a pressing challenge. This article briefly analyzes the requirements for temperature, pressure, or density compensation in flow meters, and outlines temperature and pressure compensation strategies based on the characteristics of liquids, gases,
