Product: PDTX4

Principle of Operation

Featuring positive displacement technology, the setup is quick and easy. To change any key functions, simply use the magnet that is attached. No opening of the enclosure is required. To prevent the magnet from entering the programming mode inadvertently, an on board jumper controls ability to allow programming via external magnet. An isolated input also allows for remote rest of the totalizer. A 4-20 mA rate ouput with user programmable filtering and scaling is also provided for remote indication.
