The Mini-AT is a standalone full-featured electronic gas volume corrector. The electronic corrector can be mounted on rotary and turbine meters and diaphragm gas meters that have a rotating shaft (instrument drive) output. The Mini-AT is also compatible with meters that provide high or low frequency meter pulses when the unit is retrofitted with the applicable interface board.
Honeywell Mercury Instruments MINI-AT Electronic Corrector is a full featured electronic gas volume corrector providing corrected gas volume with audit trail.
The user can connect to the Mini-AT through Mini-AT Link or MasterLink32 software on a desktop PC, Laptop, Palm, or Pocket PC computer, to configure and download the Mini-AT. The Mini AT is available in standard meter mount, wall mount and pipe stand mount.
The electronic corrector's primary function is to correct the gas meter volume and record the customer's usage information. It is essentially the cash register between the utility and customer. Correctors produce accurate results from 0.002%-0.005% of the corrector's pressure range.
Natural Gas Meter Evolution
From counting lamp lights to compensating for pressure and temperature, increasing accuracy has been the driving force behind natural gas meter evolution.
Gas Laws and their influence on Natural Gas Flow Measurement
By reviewing gas laws, we demonstrate how simple variables, such as temperature, pressure and volume influence gas flow measurement and gas instrumentation.
Gas Measurement from Uncorrected Flow Rate to Volume Correction
A volume corrector is an instrument designed to take uncorrected volumetric gas flow and correct for the influences of pressure and temperature.
