MAGNETIC LEVEL GAUGESPRINCIPLES AND APPLICATIONSMAGNETIC LEVEL GAUGES1MAGNETIC LEVEL GAUGESmanufactured By KLINGER Limited Perth Western Australia

MAGNETIC LEVEL GAUGES2Klinger manufactured their first magnetic level gauge in Europe in 1981.

Australian manufacture commenced in 1993.

Klinger and their licensees produce in excess of 3500 magnetic level gauges per year.

MAGNETIC LEVEL GAUGES3MAGNETIC LEVEL GAUGEOperating principle

On the dry side of the chamber is the Indicator, a display of magnetic wafers (red/white).

As the float moves up or down the magnetic field of the permanent magnet pulls the wafers through a rotation of 180 thus changing their colour.

As the float rises the flaps are turned from white to red, as the float falls, they are changed back to white again.

The level is represented at any given wafer without any external power supply.

The instrument consists of 3 main partsThe FloatThe ChamberThe IndicatorMAGNETIC LEVEL GAUGES4MAGNETIC LEVEL GAUGE

MAGNETIC LEVEL GAUGES5THE DISPLAY UNITMAGNETIC LEVEL GAUGEMAGNETIC LEVEL GAUGES6

Unique patented system of edge magnetised injection moulded ferrite wafers Aluminium display housing is used as a standard and are certified IP 67THE DISPLAY UNIT For corrosive environments a stainless steel housing is available this housing also meets IP 67 approval The display is the only one capableof accommodating media surges of up to 400mm per second MAGNETIC LEVEL GAUGES7THE DISPLAY UNIT

MAGNETIC LEVEL GAUGES8THE FLOATMAGNETIC LEVEL GAUGEMAGNETIC LEVEL GAUGES9THE FLOAT Utilizes a vertically mounted omni directional magnet system The float is not pressurized or vented It is unguided and free to rotate in the chamber The magnets used can accommodate temperatures of up to 400C400mmper second

Conformity to NACEMAGNETIC LEVEL GAUGES25The dead band low (DBL) or high (DBH) are dependent on Level, Pressure and Specific gravity.

This corresponds to the minimum level of liquid to operate the float and the maximum level above that no higher levels are indicatedMAGNETIC LEVEL GAUGE
