  • Page 14: Fill Level Measurement

    4.3. Fill level measurement The KNX SO250 Tank Sensor can measure the fill level of liquids in tanks. Possible tank designs are rectangular tanks, spherical tanks, vertical or horizontal tanks. If more than one similar tank exist in a battery only one tank needs to be described for the KNX SO250 to calculate the content according to the specified tank number.
