The LN Potentiometric Level Transmitter provides accurate reliable measurement in difficult environments utilizing potentiometric technology. While Anderson’s dual diaphragm hydrostatic level technology provides proven accuracy and reliability in atmospheric inventory tanks, applications such as filler bowls and other shallow vessels, pressurized tanks and environments with wide temperature swings can prove challenging for pressure based level systems. Utilizing potentiometric technology, the LN excels in these traditionally difficult applications. Fast reacting, the LN samples interior level at ten times per second allowing accurate readings while filling or dispensing product.

The stainless steel enclosure is also built to withstand the rigors of harsh environments. Resistance to vibration and moisture from wash downs is handled with typical Anderson rugged construction. The water tight and reliable quick disconnects round out this dependable design. As with all Anderson level transmitters, the LN meets FDA materials, and 3-A “third party verification” standards and is backed by a one-year warranty.
