The magnetostrictive liquid level sensors are based on the magnetostrictive measurement principle. The liquid level sensors satisfy the demand for a digital communication interface that offers the liquid level market unsurpassed flexibility to meet most process application conditions. The Magnetostrictive liquid level sensors provide 3-in-1 measurement for liquid level, interface level and temperature measurements. And there is no scheduled maintenance or recalibration needed once the sensor is installed and calibrated.  The output of Magnetostrictive liquid level sensors is through ModBus, which is communicated via a 4 wire multi-drop power and data bus (EIA485). Utilizing the Bus network eliminates the requirements for individual cable runs from each tank and this data format provides a direct interface to most types of computers and digital communication equipment.
