Flow meter

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,

Seven Key Points for Electromagnetic Flowmeter Selection: Accuracy and Functionality: Choose the appropriate accuracy level based on measurement needs, and consider necessary functions such as bidirectional measurement or alarms. Flow Rate and Diameter: Determine the fluid’s flow rate range and select the proper sensor diameter to ensure measurement accuracy. Fluid Properties: Consider the fluid’s conductivity,

As shown in Figure 1, the upstream pressure tapping point is located 25.4 mm from the upstream face of the orifice plate, and the downstream pressure tapping point is also located 25.4 mm from the downstream face of the orifice plate. When using flange pressure tapping, the pressure tapping flange is included as part of

Instrumentation and electrical systems can be differentiated from the following aspects: 1. Definitions and Functions Instrumentation: Definition: Refers to devices or systems used to measure, display, control, and record physical quantities such as temperature, pressure, flow, and liquid levels. Function: Primarily focused on the precise detection and monitoring of various physical quantities to provide accurate
