1. MAGNETIC LEVEL GAUGES MAGNETIC LEVEL GAUGES PRINCIPLES AND APPLICATIONS
2. MAGNETIC LEVEL GAUGES MAGNETIC LEVEL GAUGES manufactured By KLINGER Limited Perth Western Australia
3. MAGNETIC LEVEL GAUGES 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.
4. MAGNETIC LEVEL GAUGES MAGNETIC 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 Float The Chamber The Indicator
