The 46X Submersible Level Transmitters from Riels are commonly used for level measurement of liquids and dense water. It combines the ceramic measuring cell for low pressure ranges with electronic pressure transmitters from mP series digital 30. The values of the signal, which comes from the sensors of the pressure and temperature are determined by means of a compensation polynomial.
It is used in areas, which are exposed to explosion, where categories 1 and 2 are necessary. Some of its typical applications include level measurement of tanks, level measurement of fuel tanks, and for checking the alert level of manholes. The unit operates to a temperature which ranges from 0°C to 80°C.
