These tank level gauges function according to the magnetostrictive measuring process. A wire made from magnetostrictive material is integrated into the probe tube. Pulses are transmitted through the wire by means of the sensor electronics which create a circular magnetic field.
Magnets are built into the floats which magnetize the wire at the float position. Due to the superposition of the two magnetic fields a torsional pulse is created which propagates towards the probe head. The running time thus created is captured and converted by the electronics.
Additional features of FAFNIR's VISY-Stick tank level gauges include:
- monitoring of product filling level, product temperature and water level
- all parts in contact with media made from high grade stainless steel
- one float set for all media; and
- optional with 1" floats.
