Features

Faraday’s law of electromagnetic induction serves as the foundation for insertion type electromagnetic flowmeters. The two electromagnetic coils at the top and lower ends of the electromagnetic flowmeter create a continuous magnetic field, and the conductive medium in the measuring tube is comparable to the conductive metal rod in the Faraday test.

01

Insertion type electromagnetic flowmeter

One kind of flow meter used to gauge the flow of conductive liquids in big pipelines is the insertion electromagnetic flowmeter. This kind of flow meter is put right into the pipe and uses the flow's electromagnetic field to detect the liquid's flow to determine the flow rate. It is made up of a transmitter that is fixed outside the pipe and a probe that is put within the pipe. The probe detects a magnetic field produced by the transmitter, and the voltage signal that results is proportionate to the flow rate. Electromagnetic flowmeters installed by insertion are widely utilized in large pipelines when installing a full-bore flow meter is impractical. These sectors include chemical processing, wastewater treatment, and water treatment. An insertion electromagnetic flowmeter has the benefit of being able to be placed without stopping the operation, which may save both money and time.A more affordable option to full bore flowmeters are insertion flowmeters. They consist of a support rod with an electromagnetic detecting head fixed on the end.finds use in water distribution systems that are currently in use, where full bore flow meters would be unfeasible and flow metering was not initially planned for. Without requiring significant excavations or changes to the pipe work.

Reliable Electromagnetic Flow Meter Guide

Electromagnetic flow meters detect flow by using Faraday's Law of induction. Inside an electromagnetic flow meter, there is an electromagnetic coil that generates a magnetic field, and electrodes that capture electromotive force(voltage).This is the quantity of heat energy needed to increase a pound of water's temperature.

Electromagnetic Flow Meter Calibration

The heat energy transported in a heating or cooling system is measured using an electromagnetic BTU (British Thermal Unit) meter. It uses temperature sensors in conjunction with electromagnetic flow measuring methods to function.Place the master meter in series with the flow meter under test.

Principle Insertion type electromagnetic flowmeter

Faraday’s law of electromagnetic induction serves as the foundation for the operation of the Insertion type electromagnetic flowmeter. The two electromagnetic coils at the top and lower ends of the electromagnetic flowmeter create a continuous magnetic field, and the conductive medium in the measuring tube is comparable to the conductive metal rod in the Faraday test. A conductive material will cause an induced voltage to be produced. The induced voltage produced is measured by two electrodes within the pipe. Through a non-conductive lining (rubber, Teflon, etc.), the measuring pipeline is electromagnetically insulated from the fluid and the measuring electrode.

Applications

Heating and Cooling Reactors

Heating and cooling reactors are crucial components in various industrial processes, particularly in chemical, pharmaceutical, and food industries. These reactors are used for carrying out reactions under controlled temperature conditions.

Disinfecting and
Sterilizing

Disinfection and sterilization are critical processes across various industries, particularly in healthcare, pharmaceuticals, food processing, and biotechnology. These applications ensure the elimination of harmful microorganisms.

Waste Heat Recovery Boilers

Waste heat recovery boilers are essential components in industries where significant amounts of heat are generated during various processes but are typically wasted. These boilers capture this waste heat and convert it into useful energy, thereby improving.

Dyeing WasteWater

Treatment of highly coloured wastewater containing a variety of dyes in varying quantities is a major component of wastewater treatment in the textile and dye industry.The flow of dye into the interior of the fibre as well as the interaction between a dye .

Exhaust Gas Treatment

Exhaust gas treatment systems (EGTS), also referred to as SOX scrubbers, are an alternative to these solutions that clean the exhaust gas in order to reduce SOX emissions to a level that is equivalent to the acceptable fuel sulphur content.

Fertigation System

Fertigation is the process of injecting fertilisers into an irrigation system for the purpose of amending the soil, the water, and other water-soluble goods. Adding chemicals to an irrigation system is known as chemigation, which is connected to fertigation.
