How does a magnetic level indicator work?

The working principle behind a magnetic level indicator is that the measuring instrument shares the same fluid — and therefore, the same level — as the vessel. The level indicator is attached to the vessel and connects directly with the fluid to be measured. Within the chamber is a float with a magnet assembly inside.

How does a magnetic water level sensor work?

How Magnetic Reed Liquid Level Sensors Work. The purpose of a float switch is to open or close a circuit as the level of a liquid rises or falls. The float encases a sealed magnet, which moves up and down the length of the stem as a fluid level rises and falls.

What is the basic principle of magnetic gauge?

Magnetic level gauges work on the principle of communicating vessels, therefore the level in the measuring chamber will be the same as the level in the vessel. The measuring chamber is fitted with a float, which has a magnet inside.

What is magnetic indication?

A magnetic level indicator is an externally mounted chamber with visual indicators that are completely isolated from the process liquid. Inside the chamber is a magnetic float that rises and falls with the level of the liquid. Magnetic level transmitters were initially introduced as alternatives to sight glasses.

How does a magnetic level gauge read liquid level?

The indicator is magnetically coupled to the float and moves up and down with the liquid level. The indicator allows the operator to read the level from more than 100 feet away. The only moving parts are the float and the indicator.

How does a magnetic level indicator ( MLI ) work?

The Magnetic Level Indicator (MLI) is a simple, rugged instrument designed to indicate level or interface. It indicates level using a float magnetically coupled to an index or a column of rotating flaps.

Why do you need a Magtech level indicator?

They provide non-invasive level indication while reducing leak points and fugitive emissions. Combined with our externally mounted transmitters and switches, Magtech magnetic level indicators provide a complete, redundant and cost-effective level solution. Easy to install, no extra piping required in most applications

Why are magnetic level indicators preferred over reflex indicators?

Magnetic level Indicators (MLI) are preferred Level Indicator (compared with glass or reflex indicators) because of safer performance against external explosions and high pressure application. There is a difference between the true liquid level and the indicator position because:
