Nisan Magnetic Level Gauge is used wherever fluid level has to be monitored, indicated, and controlled in a reliable way, especially with corrosive, toxic and inflammable fluids with a viscosity up to max. 5000 mPa s. The Nisan Magnetic level indicators offer a reliable, accident-free and maintenance-free usage, through a simple and break-resistant construction at a maximum process pressure of 200 bar and a temperature range from –50 through 400 °C. The fluid level is indicated directly with a separation of the measurement and indication area. The magnetic transfer of the fluid level from the tank to the indicator is continuous and vibration-resistant, even in the case of fast changing levels. Magnetic Level Gauges are principally designed as an alternative to glass level gauges. MLGs are now widely used in all industries as they avoid direct contact with indicator system; it eliminates need of glass for direct level indication and prevents chemical spillage due to breakage of glass. It is possible to mount the indication rail in any position on the pipe diameter. There is no corrosion of the indication system. The Nisan instruments may be used in open or closed vessels. A definite level measurement without any power supply is guaranteed due to a continuous rotation of the Flappers, even if a power loss in the plant occurs.
