Flow meter

The common methods for anti-freezing and anti-condensation in chemical plants include drainage, insulation, heat tracing, and circulation. Winter anti-freezing and anti-condensation should be implemented based on the operating status of the equipment and pipelines, combined with the issues and experiences encountered in previous winters, and adopting one or more of these methods. 1. Drainage The […]

1. Overview The intelligent vortex flowmeter is mainly used for measuring the flow of fluids in industrial pipelines, including gases, liquids, and steam. Its characteristics include low pressure loss, a wide range, and high accuracy. It is almost unaffected by fluid density, pressure, and temperature parameters when measuring the working volume flow. With no moving

Verification and calibration may seem similar at first glance, but they are fundamentally different processes. Both fall within the realm of metrology and require comparing the measured values of an instrument against a higher-precision standard. In this way, both verification and calibration play a crucial role in ensuring traceability and maintaining measurement accuracy. However, the

Choosing the right vortex flowmeter for your specific application requires consideration of various factors, such as the medium being measured, flow rate range, and installation conditions. Vortex flowmeters are versatile and can be used to measure gas, liquid, and steam. However, certain conditions and media types may not be ideal for vortex flowmeter usage. 1.

In modern industrial, medical, and aerospace systems, instrument self-diagnostic fault outputs serve as a critical feature for maintaining system health. When an instrument detects a fault within itself, it sends out a warning or signal to the operator or the control system, providing valuable information for decision-making. However, when such fault warnings occur, there is

Microflow measurement refers to the process of determining the flow rate of fluids in very small quantities. This process is used across a wide variety of industries, particularly in fields like pharmaceuticals, chemicals, and precision engineering. Measuring such low volumes accurately presents certain challenges. Several instruments are available to accomplish this task, and they share

Safety Instrumented Systems (SIS) play a critical role in industrial processes, particularly in environments where hazardous events pose significant risks to people, equipment, and the environment. A well-designed SIS is crucial for maintaining safe operations, and its reliability is often defined by its safety integrity. Safety integrity measures the ability of a SIS to perform

Instrumentation operation and maintenance (O&M) workloads depend on several critical factors. Among them, instrument selection and installation practices play a vital role in the overall O&M effort required. This article will explore these two key elements in detail, expanding on how each influences long-term maintenance and reliability. 1. Instrumentation Selection Instrumentation selection is typically guided

Passive signal and active signal 1. Definition of passive signal and active signal Active and passive refer to whether there is a power supply, which is used to distinguish whether the signal instrument needs to be powered. Analog signals are all active, whether they are two-wire, three-wire or four-wire signals. Two-wire and three-wire signal instruments

In the field of instrumentation, there are technical parameters that may seem similar at first glance but actually represent distinct characteristics. Today, let’s delve into the differences and connections between two such parameters: sensitivity and precision in instruments. Sensitivity of Instruments: Sensitivity refers to an instrument’s ability to measure the smallest detectable quantity. The smaller
