The AdEM® -PTZ is an electronic counter module with the capability for live compensation for Pressure, Temperature and Supercompressibility (Z).
The AdEM-PTZ is a direct mount module for seamless integration with Romet and other popular rotary meters. Some features of the AdEM-PTZ include a full audit trail, four available output pulses, serial communication and a 15 year nominal battery life. This state-of-the-art corrector is also available in a remote mount configuration (AdEM-PTZ-r).

Romet has developed a single adapter plate that will allow our AdEM-PTZ to be installed on Romet RM 600-56000 rotary meters and RMT 600-23000 rotary meters.

We also offer a single adapter plate for Dresser B3 meters ranging from 8C to 56000 and LMMA meters ranging from 1500-16000. The AdEM-PTZ comes standard with Romet’s patented AdEM Click technology allowing for seamless installation between Romet and Dresser rotary meters.

With the AdEM Click you can carry one electronic corrector to fit all sizes and brands of rotary meters in your system.
