    NIVUS Full Pipe Configuration 16.1 Device Types The transmitter NFP is available in different versions. The transmitters primarily vary in terms of maximum pipe diameter, power supply, Ex-protection as well as the number of analog out- puts. The current type of device is indicated by the article number, which can be found on a weath- erproof label on the bottom of the enclosure.
