This article compares their applicable conditions, advantages, limitations, and provides guidance for selecting the right type for […]

Electromagnetic flowmeters are widely used for measuring the flow of conductive fluids in various industries. However, their performance depends significantly on the properties of the medium being measured. To ensure accurate and reliable operation, specific requirements must be met regarding the conductivity, uniformity, temperature, pressure, and chemical and physical characteristics of the medium. Below is

Electromagnetic flowmeters are precise instruments used in various industries for flow measurement. Proper installation is critical to ensure accuracy, reliability, and longevity of the device. This article outlines key installation considerations and provides detailed guidelines for achieving optimal performance. 1. Transportation and Handling Guideline: For flowmeters smaller than DN100 (4 inches), avoid applying force to

Intrinsically Safe (IS) Instruments are critical safety devices designed for use in hazardous environments where explosive gases, vapors, or dust may be present. These instruments operate by limiting the electrical energy available to a level that is too low to ignite a potential explosive atmosphere, thus providing a key layer of safety in industries such

Electromagnetic flowmeters are widely used in various industries for accurate flow measurement. However, they may encounter operational issues that can be broadly categorized into two types: (1) faults originating from the instrument itself, such as structural or component failures; and (2) faults caused by external factors, such as improper installation, flow changes, sedimentation, and scaling.

Electromagnetic flowmeters are widely used in industrial applications for measuring the flow rate of conductive liquids. Their structure is composed of several critical components, each with a unique function. This article provides an in-depth explanation of the components, their roles, and the key considerations for their design and application. 1. Magnetic Circuit System The magnetic

1. Principle of Differential Pressure Flow Measurement When a fluid completely fills a pipeline and flows through a primary element (such as an orifice plate or nozzle), a local constriction is created. This results in an increase in velocity and a decrease in static pressure. Consequently, a differential pressure (DP) forms before and after the

Target flow meters are widely used to measure the flow of liquids, gases, or steam. Below are the common faults encountered in practice, their possible causes, and recommended maintenance solutions. 1. No Flow Display Possible Causes: Power FailureIssues such as circuit breaks, short circuits, or power module damage can result in the flow meter failing

Flowmeters often require a certain length of straight pipe (straight run) upstream and downstream to ensure accurate readings. However, in many practical installations, site conditions make it difficult or impossible to meet these requirements. So, what can you do in such situations? Below are detailed methods to address insufficient straight pipe length for flowmeters. 1.
