Products Overview

The Magnetic Level Gauge is the instrument to read a level indication in whatever plant or operating conditions giving free maintenance, preventive security against leakage, environmental safety, sure and trouble free application with chemically aggressive, pollutant, harmful or poisonous, inflammable or explosive, optically similar fluid interface.

OPERATING PRINCIPLE :

The operation of the magnetic level gauge is based on some elementary physical principles:
 The principle whereby the liquid in communicating vessels is always at the same level
 Archimede’s principle according to which a body immersed in a liquid receives a buoyancy equal to the weight of displaced liquid.
 The principle of attraction between North and South poles of two permanent magnets and that of repulsion between like poles.

This principle has two applications in the magnetic level gauge:
 First between the magnet in the chamber float and every single magnet of the indicating scale.
 Second between the magnets of the indicating scale.

THE MAGNETIC LEVEL GUAGE CONSISTS OF :

 A vertical chamber consisting of a tube of suitable diameter and thickness containing a float wherein a permanent magnet is placed exactly on the liquid level line.
 Two horizontal stub pipes for connection to the vessel containing the liquid of which we wish to know the level.
 Two stop valves (recommended, but not mandatory) one on each stub pipe, to isolate the level gauge.
 An indicating scale, outside the vertical chamber, consisting of a case of non-magnetic material with transparent.
 Front face containing a set of small permanent magnets enclosed in small cylinders which can rotate on their horizontal axis.
 These cylinders show an external surface having two different colours.

TYPES OF MAGNETIC LEVEL GAUGE : 1 CAPSULE TYPE 2 FLAPPER TYPE

Applications:
The application range is very wide and includes all the situations where the fluids are:
 at high pressure, at low or high temperature
 at low pressure, at low or high temperature
 chemically aggressive
 pollutant to environment
 noxious or poisonous for people health
 inflammable or explosive
 with identical optical characteristics of the superimposed phases (interface)
