ZT-100 Electronics
The measurement is the same. What drives it, and what it can talk to, is a choice you make separately from the pipework.
One Enclosure. One Probe Interface. Four Boards.
A ZT-100 is two decisions, not one. The measuring element — an F-Series or S-Series spool, or an I-Series insertion probe — is chosen on line size, pressure class and how the instrument meets the pipe. The electronics are chosen on the power you have available, the signals you need to carry, and the area classification you are installing into.
Those two decisions are independent. The same board sits behind any of the measuring elements, and the same measuring element accepts any of the boards. That is what makes a range change, or a move from a two-wire loop to a fully powered instrument, something other than a new instrument in a new nozzle.
