Measuring flow in large pipes with insertion type flow meters.
If you need to measure the fluid flow of a larger pipe diameter, you are most likely to choose an insertion type flow meter.
But what insertion type flow meter should you use?
The market has insertion electromagnetic flowmeter, insertion vortex flowmeter, insertion ultrasonic flowmeter, insertion ultrasonic flowmeter and so on.
Next, let us compare various insertion type flow meters. Hope to help you choose the right insertion type flow meter!
When should you use Insertion type flow meters?
- When the pipe diameter is large;
- When there is a tight inner lining;
- When the scale in the pipe is serious;
- When the pipe is a poor conductor of ultrasound;
- When the external clamp probe fails to reach the required signal strength or the measurement is unstable.

Insertion type electromagnetic flow meter working principle
Faraday’s Formula
E is proportional to V x B x D where:
E = The voltage generated in a conductor
V = The velocity of the conductor
B = The magnetic field strength
D = The length of the conductor
The insertion magnetic flowmeter is based on Faraday’s law.When measuring flow, a liquid flows through a magnetic field perpendicular to the direction of flow and induces a voltage proportional to the average flow rate (volume flow). Its induced voltage signal is detected through two electrodes that are in direct contact with the liquid. Voltage signal will be transmitted to the smart transmitter through a dedicated cable. The smart transmitter performs calculations based on the magnitude of the electric potential and the mathematical model of the electromagnetic flow. And converts it into a flow signal for on-site display. Including instantaneous and cumulative quantities can be display. Then output the standard 4 ~ 20MA and 1 ~ 5VDC signals to the flow secondary meter or DCS.

Q&A
What is the difference between inline and insertion flow meter?
1. The main difference between Inline flow meter and insertion flow meter is the different structure.
Inline flow meter is directly installed on the pipeline, and the flow measurement element and the pipeline are connected together.
While insertion flow meter needs to insert the measuring probe into the pipeline.
2. Different measurement accuracy.
Inline flow meter has relatively high measurement accuracy and is suitable for high-demand occasions.
While insertion flow meter has relatively low measurement accuracy and is suitable for general occasions.
3. Different applicable pipe sizes:
Generally, small-diameter pipes, such as DN25, DN100, etc., can choose Inline flow meters.
While insertion flow meter is mainly suitable for large-diameter pipes. For example, DN1000, DN2000, etc.
4. Different installation and maintenance costs:
The installation and maintenance costs of Inline flow meters are higher than those of insertion flow meters. Because Inline flow meters need to be installed directly on the pipeline, more labor and time are required.
While insertion flow meter only needs to insert the measuring probe into the pipeline, the installation and maintenance costs are relatively low.
Of course, the choice of Inline or Insertion flowmeter should be based on the requirements and conditions of the actual application.
