The working principle of the insertion electromagnetic flowmeter is based on Faraday's law of electromagnetic induction.
The working principle of the insertion electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. In the electromagnetic flowmeter, the conductive medium in the measuring tube is equivalent to the conductive metal rod in the Faraday test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows through it, an induced voltage is generated. Two electrodes inside the pipe measure the induced voltage produced. The measuring pipe is electromagnetically isolated from the fluid and measuring electrodes by a non-conductive lining (rubber, Teflon, etc.).
1. First, open a hole of Ф60-62mm directly above the measurement point of the pipe. The edges around the round hole need to be bright and free of burrs and gas cutting scars.
2. Unscrew the device from the sensor and reliably weld it to the above-mentioned opening. Requirements: Make the lower end of the device flush with the inner surface of the pipe and ensure it does not leak.
3. Loosen the three locking screws of the sensor and pull out the detection rod and detection head for later installation. (Note: The user is not allowed to open the connection between the detection head and the piercing rod).
4. Wrap hemp lead oil or PTFE tape on the upper thread of the device, then tighten the ball valve and sealant locking mechanism on it.
5. Slowly insert the detection rod from above, tighten the locking nut slightly, press down the insertion rod to measure L2, and measure the same size as the recorded L2, and the installation is completed. Insertion electromagnetic flowmeter installation process.
