Insertion flowmeter is a type of flowmeter classified according to its structural form, which includes various flowmeters with different working principles. Insertion flow meters have made significant progress, and from the perspective of the overall development trend of flow meters, they have strong vitality and occupy an important position among many flow meters.

Manufacturer of insert type flowmeter

Flowmeters are classified into 11 major categories based on measurement methods and classifications, including volumetric flow meters, differential pressure flow meters, float flow meters, turbine flow meters, electromagnetic flow meters, fluid oscillation flow meters, mass flow meters, insertion flow meters, open channel flow meters, probe flow meters, ultrasonic flow meters, and other flow meters (including laser flow meters, target flow meters, impulse flow meters, and marking flow meters, etc.).

There are various forms of inserted flow meters that have been widely promoted and used. According to the working principle of the detection head of the inserted flow meter, it can be divided into inserted turbine, inserted vortex street, inserted electromagnetic, averaging tube, and thermal flow meter, etc; According to the number of measuring points of the insertion flowmeter, it can be divided into two categories: point flow and radial flow

Working principle of insert type flowmeter

The working principle of the Insert type electromagnetic flowmeter is based on Faraday’s law of electromagnetic induction. In an electromagnetic flowmeter, the conductive medium inside the measuring tube is equivalent to a conductive metal rod in Faraday’s test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows through, an induced voltage is generated. The induced voltage generated by measuring the two electrodes inside the pipeline. The measuring pipeline achieves electromagnetic isolation from the fluid and measuring electrodes through non-conductive lining (rubber, Teflon, etc.).

Performance characteristics of insert type flowmeter

Low frequency three value rectangular wave constant current excitation, not affected by power frequency and various stray interferences on site, works very stably and reliably.
Adopting a new technology of non-uniform magnetic field and a special magnetic structure, the magnetic field is stable and greatly reduces the volume and weight, making the flowmeter have the characteristics of small and lightweight
Adopting specialized electronic circuits with automatic zeroing function for air traffic control.
On site, the range can be modified online according to the actual needs of the user.
● No movable parts, no obstruction parts. There is almost no additional pressure loss during measurement.
The measurement results are independent of physical parameters such as flow velocity distribution, liquid pressure, temperature, density, viscosity, etc
● Easy to use, only need to connect the power supply after installation, no other operation is required, and standard signals can be output, which is convenient for non professionals to use

The main applications of insert type flow meters

Power generation, cogeneration, and heating industries; Aviation, aerospace, shipbuilding, nuclear energy, and weapons industries; Mechanical, metallurgical, coal mining, and automobile manufacturing industries; Petroleum and chemical industries; Pharmaceutical, food, and tobacco manufacturing industries; Forest industry, agricultural reclamation, and light industry.
