1. INTRODUCTION TO AdEM®-PTZ
AdEM®-PTZ is an electronic gas volume conversion device, which provides corrected
volume that is temperature and pressure corrected to standard conditions; applying
compressibility correction factor according to NX-19 or AGA8 or SGERG88 formula
(see Correction Equation for details). Romet combines the power of its field proven
gas measurement technology and integration of computer-based software to come
with the product AdEM®-PTZ. The device can be mounted on Romet rotary meters
or
other manufacturers’ pressure bodies. AdEM®-PTZ can be used either as a stand-
alone device or linked to a computer running RometLink software. RometLink is a
powerful tool for device management and advanced data collection/energy
management system.
