Dresser

Micro Corrector - IMC/W2

Integral Volume Correction Differential Pressure (DP) Monitoring

Versions: ptz-dp + LOG, T-dp + LOG, ptz + LOG, P + LOG, and T + LOG

GE Oil & Gas offers an integrated solution,

the Dresser Differential Pressure (DP) Micro Corrector,

which monitors meter health by continuous

measurement of the differential pressure

drop across the meter. The Dresser Micro

Corrector DP is capable of learning the

differential pressure curve for an individual

meter. During the learning period, DP is

monitored using the values present in the

Differential Test Acceptance Calculator (DTAC).

The Dresser Micro Corrector DP retains the last

valid average differential pressure measurement on

the LCD of the corrector along with the date when

this occurred. It also displays the average line pressure,

average line temperature and meter flow rate for that

same date. The differential pressure test information

required to be in compliance with state Public Utility

Commission (PUC) requirements is available with the

push of a button.

This offers operating efficiencies as the number of

return trips to the meter set is reduced, and reduces

the need for venting gas during periods of low

consumption. Differential pressure test results are

also logged in the data logs.

Developed from the proven IMC/W platform, the

Dresser Micro Corrector provides volume correction

through a simple-to-use interface. Features such as

improved low flow accuracy, enhanced data logging

capability, and reduced accuracy test times combine

to offer a complete solution to major customers.

The Dresser Micro Corrector, model IMC/W2,

an integral corrector rated for Division 1 hazardous

locations by the Canadian Standards Association (CSA)

and ATEX.
