Magnetic level indicators are low-maintenance alternatives to sight glasses and other level indicators. They provide non-invasive level indication while reducing leak points and fugitive emissions.
Magnetic level indicators consist of a chamber, a magnet equipped float which rises and lowers with the fluid level, reed switches and an indicator which is mounted to the chamber.
The indicator houses a column of small flags which indicate the level of the fluid in the chamber, based on the position of the float. As the fluid level rises and lowers, the float rises and lowers as well, and the flags are tripped from one orientation to the other.As the float rises and falls with the process level, tripping the flags (reed switches), it also stimulates any attached transmitters and switches, providing a signal back to the control system.
