Contact level measurement of liquids and liquid-liquid interfaces without any power supply or with a guided wave radar
L21 Magnetic Bypass Level Gauge
The L21 level gauge is used to measure the liquid level/interface in open and pressure tanks. It is made from high quality stainless steel. The wetted parts are made from materials resistant to chemicals. As this type of level gauge requires no power supply, it can be used for measuring flammable, chemically aggressive or toxic liquids at high operative temperature or pressure. On request, the level gauge can be fitted with limit contacts to monitor minimum/maximum liquid levels in tanks, to switch a pump on/off, to open or close valves etc.
