Which is more suitable, radar or reed switch?
Thread Content
To measure the liquid level in a cylinder, using a differential pressure transmitter is inaccurate due to issues with density. Radar and reed switches don’t depend on density at all; which one is better? Radar is too expensive.
Magnetic float level gauges are useful, but reed switches lack reliability; it is recommended to use Hall elements in place of reed switches! This post was last edited by liuei on 2009-2-18 22:47.]
The magnetic float in a magnetic float level gauge is related to the specific gravity of the material being measured; therefore, given your circumstances, a magnetic float level gauge is not suitable for use. If remote transmission is not required, a glass tube level gauge is a good choice. If the storage tank is not very large, weighing is also a good option.
The weighing method won’t work because the density is inaccurate!
Capacitive level gauges, radio frequency admittance level gauges, and magnetostrictive level gauges can be considered. The first two types of media need to be conductive, while the latter one performs very well
It’s better to choose magnetic floating balls; they are inexpensive, simple, and reliable. We’re using Ryan Xinxin’s; it’s good
