Features
Features- High acurracy and high resolution
- Compact with a small bore fitting
- Initial setting is not required
- In addition to stainless steel, corrosion resistant resin (PVC, PFA etc.) is also available.
- Not affected by gas, pressure, etc. which are generated in the tank.
Operating Principles
It applies the magnetostrictive phenomenon by Wiedemann effect. “Torsional strain” is generated on the magnetostrictive line by the magnet in the float moving along the stem. The liquid level is detected by measuring the propagation velocity of the strain.
