How It works
The working principle of a magnetic level gauge is that it is connected to the container, so the liquid level in the measuring chamber is the same as the liquid level in the container. A float with a magnet inside is installed inside the measuring chamber. The float floats on the medium, and the magnet drives the baffle of the indicating guide rail to rotate.
The float inside the measuring tube is a standard non-pressurized type, without magnetic or mechanical guidance. This design makes it safer than standard pressurized floats. Hadro can manufacture pressurized floats upon request. The appropriate float for this medium can be selected based on the following process conditions:
Medium
Density
Operating Pressure
Temperature
Applications
Liquid Storage Tanks
Used to measure levels in chemical storage tanks, including tanks holding acids, solvents, oils, and other hazardous chemicals.
Reaction Vessels
Essential for monitoring liquid levels in chemical reactors to ensure proper mixing, control of reactions, and safety in the process.
Mixing Tanks
Used in blending and mixing tanks where precise monitoring of liquid levels is crucial to maintain the correct proportions of ingredients.
Separators and Process Vessels
Used in separation processes where liquids and gases need to be monitored continuously for level control.
Refining Process
Magnetic level gauges are used in various stages of the refining process, ensuring accurate level readings in distillation, extraction, and fractionation columns.
