In the field of instrumentation, understanding the distinction between a sensor and a transmitter is crucial for designing and maintaining efficient control systems. Both devices are integral to data acquisition and process automation, but they serve different functions within a system. Here’s a closer look at what differentiates a sensor from a transmitter and how […]

With the continuous introduction of new safety instrument system specifications (such as IEC, GB, SY, SH, HG, MHG, and various industry standards), the options can become overwhelming, leaving one unsure of how to proceed. To choose the appropriate safety instrument system specifications, the following aspects can be considered: I. Understand Your Own Needs 1. Determine

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

Improper installation location When installing the vortex flowmeter, avoid installing it too close to the curved part of the pipe, the near end of the pump or the valve to avoid vortex or vibration that may affect the measurement accuracy. Pipeline flow instability If there is obvious turbulence, vortex or flow velocity pulsation in the

Vortex Flowmeters: Advantages: Accuracy and Stability: Vortex flowmeters provide relatively high accuracy in measuring steam flow and maintain stability over a wide range of flow rates. Low Maintenance: They have no moving parts, which makes them more durable and less prone to mechanical wear. Wide Range of Applications: Suitable for measuring steam, liquids, and gases,

Radar flowmeter, a device that uses the principle of electromagnetic wave reflection to measure fluid velocity, has been widely applied in the industrial field due to its non-contact measurement, high accuracy, and strong adaptability. Today, we will explore the working principle of radar flowmeters and their applications in various scenarios, with the aim of providing

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

In the context of a flow meter, “E Ex iaⅡC T4” refers to the device’s classification according to international standards for electrical equipment used in explosive atmospheres. Here’s a breakdown of each part: E Ex: This indicates that the equipment is designed and certified for use in explosive atmospheres, following the European ATEX (Atmosphères Explosibles)

1. The Impact of Vortex Flow Meters on the Accumulation of Flow Surface in Vortex Generators If there are viscous particles in the measured fluid, they may gradually accumulate on the upstream surface of the vortex generator, causing its geometry and size to change. As a result, the flow coefficient will also change accordingly. Therefore,

In industrial production, accurate measurement of steam flow is crucial for ensuring the stability and efficiency of the production process. Currently, the most commonly used methods for steam measurement are vortex flowmeters and differential pressure flowmeters. In practical applications, temperature and pressure compensation is an essential step to enhance the accuracy and reliability of these
