Sharing information on liquid level measurement in reaction vessels

Has a level gauge been installed or not? I think the space is quite limited; since there is a stirrer in use, for such conditions it’s possible to use radar to measure the liquid level above the heating coil, and set up a level alarm in the control panel. Be sure to install short pipes to avoid blind spots, as this will ensure fairly accurate measurements.

Yes, it’s measured using radar. Small-angle radar can be avoided

Both the radar and pressure sensing are not very reliable; measurements are inaccurate when the liquid level is unstable. It is recommended to use an external liquid level sensor for the bottom and top of the reactor in Unicom. Each has its drawbacks.

It is recommended to use a contactless 80G frequency-modulated continuous-wave radar level gauge. The unstable liquid level in mixing tanks is due to the special conditions at the site; the 80G radar has strong interference resistance, a small beam angle, and provides stable and reliable measurement results! High precision, small blind spot. If there are anyone who is interested in radar in the future, feel free to add me on WeChat for ongoing communication! V: 15240016224

Firstly, the dielectric constant of the material must meet the requirements of radar waves, and the material should not form foam easily during mixing, as this could interfere with the radar. If all of the above conditions are met, a high-frequency radar using FMCW technology can be chosen; the antenna is installed vertically at the mouth of the tank, between the stirrer blade and the inner coil. If the same tank is to be used for multiple processes (reaction in the initial stage, heat retention in the intermediate stage, and distillation and recovery in the final stage), the radar antenna must be kept away from the vapor lift pipe, as the dense vapor streams generated during distillation can interfere with the radar waves. In applications for high-frequency radar reactors, for more economical imported options, Kolon and Viga can be chosen; for those of medium quality, Rosemount is a good choice; and among imported products, E+H offers the greatest stability. I hope it can be helpful.

Stirring and coiling cause significant interference in radar measurements, as the distance is too small. If the medium does not crystallize, the stirring force is not very strong; however, since the storage tank is quite tall, a guided-wave radar equipped with a wave-dampening tube can be used, or a DN50 guide tube can be inserted directly.

The storage tank is not tall; there was a typo earlier
