SECU tank relay for the highly accurate, continuous level measurement for pressure-free tanks with liquid products. Is an electronic content remote indicator for pressure-free tanks with liquid operating medium and additional control functions with the help of 2 relay outputs. Implementation of various control functions, for example, for external alarm, fuel tank removal switching or dry-run protection a pump. Display device with 2-line LCD display. Function: The tank capacity is determined by a measurement of the hydrostatic pressure of the full height. After entering the tank data in the display unit is automatically at the time of commissioning, the conversion of the measured values with on-screen display. For the connection of hydrostatic sensors or pressure transmitters with 4 - 20 mA or 0 - 5 V interface.Benefits and features:Output of the measured data on the display of the digital display device in either liters, volume percentage % (V/V) or as a full-height in centimeters.Disp
