These intelligent transmitters are designed to measure  liquid level, interface or density of liquids. The measurement is based on the Archimedes buoyancy principle. The transmitters can be set conventionally using the local keys. Bidirectional communication is possible using the PC Software ABO991 or the universal hand terminal HT991 via the standard HART protocol. The transmitters are approved for use in hazardous areas.
