Description

The electro-pneumatic tank contents indicator DTA 20 E consists of a control unit with with power supply 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, spherical, cylindrical and horizontal) are stored.
