  • Daily measurement and worldwide access to consumption data
  • Local display and push message (adjustable) when minimum level is reached
  • For fuel oil, (bio) diesel, water and other mediawith a density between 0.5 and 1.5 g/cm3


Location-independent level measurement with digital display and minimum level signal (reserve level alarm). If the product is operated in conjunction with the AFRISOhome gateway, the tank operator/owner can read the level on a mobile device in addition to the local display. Suitable for tanks up to 400 cm liquid level. For fuel oil EL, L or diesel fuel, FAME 100 % as biodiesel (EN 14214) and water (no drinking water!) and for AdBlue®. In addition, DTA 20 E can be used for level measurement with all
non-corrosive liquids with a density from 0.5 to 1.5 g/cm3. Remote measurements (measuring line) up to 15 m.


The electro-pneumatic tank contents indicator DTA 20 E consists of a control unit, an EnOcean wireless module, a digital display and a measuring line. Measured values are displayed in litres, % and liquid level (cm). Simple operation and setup via three function keys at the device. DTA 20 E measures the level (adjustable interval) and transmits it to the AFRISOhome gateway via EnOcean wireless. In addition, measurements can be taken by means of pressing the control key (Push-to-Read function). If the level falls below a minimum level that is freely adjustable as a percentage, the backlight of the display flashes red to indicate an alarm during the measurement. In addition to indication on the local display, the tank owner/operator can receive a push message on the smartphone or tablet. Standard tank shapes (linear and cylindrical, horizontal) are stored.
