Dresser Electronic Temperature Compensator (ETC)

Upgrade the accuracy and reliability of your gas metering with the Dresser Electronic Temperature Compensator (ETC). Designed as a direct replacement for mechanical temperature-compensating indexes, the ETC delivers precise gas volume readings by automatically adjusting for temperature and fixed pressure factors.

With a 20-year battery life, AMR compatibility, and real-time data logging for 150 days, the ETC brings modern performance to Dresser Series B and A (LM-MA) meters. This advanced electronic temperature compensator simplifies installation and eliminates the need for manual calibration, software tools, or routine maintenance.
