MAGNETIC LEVEL GAUGES


PRINCIPLES AND APPLICATIONS


MAGNETIC LEVEL GAUGESmanufactured By KLINGER Limited Perth Western Australia


Klinger 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 GAUGESMAGNETIC LEVEL GAUGE

Operating 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 parts The FloatThe Chamber

THE DISPLAY UNIT

MAGNETIC LEVEL GAUGE


• Unique patented system of edge magnetised injection moulded ferrite wafers

• Aluminium display housing is used as a standard and are certified IP 67

THE 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 GAUGESTHE DISPLAY UNIT


THE FLOAT


MAGNETIC LEVEL GAUGESTHE 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 400°C

THE FLOAT



For corrosive applications, we can :

1. Use PP, PVDF or UPVC plastic floats for low temperature low pressure applications

2. Use PFA, PVDF, HALAR or Carbon coated stainless steel and titanium floats for higher temperature and higher pressure applications

THE FLOAT



To enable us to design a float, we need the following information :

1. Pressure

2. Media and concentration

3. Temperature

4. Specific gravity

For interface applications , we need the following additional information :

1. Both media

2. Both specific gravities

THE CHAMBER


MAGNETIC LEVEL GAUGESTHE CHAMBER


Welded or seamless pipe.

ASME B31.3 construction is possible

Butt weld , x-ray are all possible

Conformity to NACE


The 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 indicated

Combined MagneticLevel Indicator andGuided Wave Radar


‘LevelSure’

NEW PRODUCT

Guided wave radar – microwave pulses are transmitted along a waveguide suspended from the top of the measuring chamber.

As the pulses come in contact with the media they are reflected back along the waveguide and are detected at the electronics in the headshell.

The time elapsed is measured to determine the liquid level with a measurement accuracy of +- 3mm
