Magnetic Level Gauges, depend not only on the integrity of the chamber but also on the float design and the ability to satisfy all design parameters, ie. specific gravity, pressure and temperature, without compromising the magnetic linkage to the display and associated controls.
Many competitive systems sacrifice display performance by using smaller and weaker magnet systems to achieve low SG and higher pressures, invariably with detrimental effect. Others use guided and vented floats to achieve the same result, which again can prove limiting and troublesome
Magnetic Level Gauges
The Magnetic gauge is designed so that the liquid being measured is enclosed within a sealed chamber.
A stainless steel, titanium or plastic float fitted with a permanent omni-directional magnet moves freely inside the chamber and actuates the magnetic wafers within the indicator.
As the float rises or falls with the liquid level each wafer rotates 180 deg and so presents a contrasting colour. Those wafers above the float show white, whilst those level and below show red – the indicator then presents a clearly defined and accurate level of the liquid in the chamber.
The wafers resist accidental disturbance (e.g. vibration) due to their edge magnetisation and mutual attraction.
To complement the range, the Magnetic Gauge can be supplied with Alarm Switches or Transmitter and Controller to remotely display the liquid level.
Indicator
Aluminium or Stainless Steel outer housing can be assembled to any length and mounted to suit the best viewing position.
Coloured
Wafers 25mm wide, red and white (or green, red and yellow) remain magnetically locked in the vertical position until disturbed by the greater magnetic force of the float magnet.
Automatic Float Warning
The wafers at the bottom of the indicator are mounted with their colours reversed. Should the float reach that level, they again present a sharp, immediately readable indication of float failure.
Sealed Float
Sealed Float of reinforced stainless steel, titanium or corrosion resistant plastic.
Sealed Chamber
Sealed chamber fabricated from stainless steel tubing, corrosion resistant plastics or other ‘exotic’ non magnetic metals.
Interface
The gauge is ideally suited for measuring liquid interfaces. Floats are available with a variety of specific gravities to suit the liquids being monitored.
Point Switches
Switches can be fitted on the gauge at any level and so provide signals at high, low and intermediate points.
Transmission and Monitoring for Remote Display
It Can be offered as a complete original equipment package or retro-fitted to an existing Magnetic Gauge.
Versatility
The simple concept of the Magnetic Gauge allows for flexible design to adapt to a variety of installation needs. Gauges can be manufactured to an almost unlimited length and in any configuration.
