This specialized level measuring device has been developed especially for the use in pressurized tanks. Two pressure sensors separately monitor the level and the internal pressure of the tank ensuring an exact measurement independent of the internal pressure that may be inside of the tank up to a maximum of 1 bar.
A pressure sensor is installed at the top of the device and evaluates the level of liquid in the tank. On tanks that have an internal pressure fluctuations (e.g., poor ventilation or fluid back flow), over-pressurization may take place that will affect the measurement.. To compensate for this, a second pressure sensor monitors the internal tank air pressure and calculates this internally. The internal communication through the data BUS calculates both measured values and a precise measuring result, independent of the surrounding pressure is transferred to the device.
Using this measuring method, it is possible to achieve precise measurements under heavy duty operation. Susceptible mechanics are excluded.
