Client Inquiry: This is a very typical and often overlooked issue in engineering sites. In a temperature measurement system, the Temperature Well, though a small metal component, plays a critical role in the overall instrument system. It is responsible for protection, heat transfer, support, and safety isolation. In other words, the Temperature Well not only […]

In modern industrial plants, pressure piping systems are responsible for transporting high-temperature, high-pressure, flammable, toxic, or corrosive media. They connect production units, storage facilities, utility networks, and safety systems. In many cases, they function as the circulatory system of the entire process plant. Because of the risks associated with these systems, installation supervision and inspection

In many industrial applications, it is essential to understand how to calculate flow rates from the output current of flow meters. This is particularly important for accurate monitoring and control of fluid flow in various systems. The output current, typically in the range of 4-20mA, correlates with the flow rate, and this relationship can be

In differential pressure flow measurement, the orifice plate, flow nozzle, and Venturi tube are the most commonly used primary elements. All three belong to the category of standard differential pressure devices, as defined in GB/T 2624, where their flow coefficients and discharge characteristics are well-established and can be used without individual calibration when designed and

Control system design is often guided by specific process requirements. Based on these requirements, necessary measuring instruments and actuators can be added. However, the design process can vary significantly depending on the current system setup and any changes in the operational environment. The three key scenarios in control system design are: Complete Control System Design

The installation and commissioning of radar level gauges are not particularly complex but require strict adherence to guidelines to avoid measurement errors—especially when dealing with high-viscosity or high-temperature media, such as asphalt. The key to success lies in attention to detail, such as installation location and probe calibration. The overall process can be divided into

The pre-shipment aging process (also known as “pre-aging” or “seasoning”) refers to the procedure in which manufacturers simulate actual usage environments and conditions before the instruments leave the factory. This involves continuous power-on, loading, or operation for a period of time to stimulate potential failures and stabilize performance parameters. In simple terms, it is like
