Dresser* Micro Corrector - MC2

Models ptz + LOG, pt + LOG and t + LOG

This second generation Micro Corrector (MC) takes the
proven MC platform and adds features to enhance the
user experience, functions that can deliver data logging,
and lower operation and maintenance efficiencies, while
retaining the features of the original product.

The Dresser Micro Corrector, Model MC2, can function
as an instrument drive (ID) or wall mount corrector. As a
wall mount model, it can also function as an economical
pressure and/or temperature recorder. Rated for Division
I hazardous locations by Canadian Standard Association

(CSA) and ATEX.

Live data screen

■

MS Excel® formatted reports allow manipulation
and sharing of information

■

Simple user terminal software allows for ease of
configuration, calibration and data downloads

■

Live data screen allows you to query the corrector
either serially or via a modem to see the current
conditions at the meter site, including a real time
display of the corrector’s battery pack voltage

Available Pressure Transducers

Micro Correctors fitted with pressure transducers are
available with either gauge or absolute transducers in
the following ranges:

Transducer Range Gauge Absolute

30 psi (2bar) X X

180 psi (12 bar) X X

350 psi (24 bar) X

1000 psi (70 bar) X X

1500 psi (100 bar) X

Temperature Probes

Two different temperature probes are available,
either of which can be fitted with a 5 or 10 foot long
armored cable. The smaller 2 inch probe can be installed
in the differential tap of the rotary meter or in small
diameter pipe. For large diameter piping, an 8-1/4 inch
probe is also available.
