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, rrector, 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 t valid average differential pressure measurement on ent 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. Dresser Meter with IMC/W2, Model ptz-dp + LOG Monitors meter health Reduces unnecessary scheduled maintenance Aids in regulatory compliance of DP testing, where applicable Last valid DP measurement displayed on LCD and live data screen Real-time differential pressure measurement Compatible with Dresser Series A (LMMA), Series B, and Romet meters DP measurement is independent of volume correction Remote monitoring capability with Dresser Micro Modems - GSM/GPRS modems dp + LOG units feature faults for high DP and meter lock-up Dresser GSM/GPRS Micro Modem

Live data screen displays current DP read, as well as last valid DP read, pressure, temperature and ow rate with date of occurrence. Learning methods are customer selectable in the user terminal software. Rotating index offers ease of meter reading, especially in non-typical installations Uncorrected instantaneous flow rate displayed on LCD can help meter differential testing in the field Maximum uncorrected peak ow also displayed on LCD ■ The SmartProve* Interface reduces meter and corrector test times by as much as 90%, and allows the meter and corrector to be tested as a complete measurement...
