Insertion ultrasonic flow meters work on the principle of Transit Time difference. Ultrasonic sensors are inserted into the surface of closed pipes. Online non-stop flow installation, maintenance and replacement of sensors are possible.

Insertion ultrasonic flowmeter is a type of ultrasonic flowmeter. This is also the principle of using the time difference method. The form of the sensor has been changed, and the installation method has been changed to plug-in type.
Insertion type ultrasonic flow meter is a product that combines the advantages of clamp on sensors and standard pipe sensors. The sensor can be in contact with the liquid to be measured, making it possible to measure a wider range of liquids. At the same time, complex pipes that cannot be measured by external clamp sensors can be measured, such as cement pipes.
Can be installed online under pressure. There is no need to close the production pipeline or disconnect the pipeline welding flange during construction.

Insertion type ultrasonic flow meter breaks through the limitations of measuring pipe materials and pipe lining materials. Sino-Inst’s Insertion type ultrasonic flow meters realize flow measurement of large diameter and complex pipelines at a better price.
From the perspective of measurement media, ultrasonic flow meters can measure both conductive liquids, such as water, and non-conductive liquids, such as desalted water and pure water. There are also various special media such as sewage, mud, mineral pulp, paper pulp, chemical fiber pulp, corn syrup, fruit juice, alcohol, drugs, plasma, etc. As long as it is a single uniform and stable ultrasonic transmission liquid, it can be measured.
There are 5 conditions for using insertion ultrasonic flowmeter:
In the above situation, an insertion flow meter may be considered.
Insertion type flow meter is a type of flow meter that requires a sensor to be installed on the pipe in an insertion form for flow measurement.
Common insertion flow meters include: insertion ultrasonic flow meter, insertion vortex flow meter, insertion electromagnetic flow meter, and insertion thermal mass flow meter.
