The Romet Rotary ECM2 (Electronically Compensated gas Meter is an Electronic Volume Corrector (EVC) module that adapts and replaces the mechanical counter on the end of a rotary gas meter. The ECM2 has many advantages:

• • Adapts to all Romet Rotary Gas Meters as well as other competitors (including Dresser LMMA series gas meters)
• • Meter Rangeablility extended to over 200:1 with an error of less then +/- 1%
• • Very low flow starts (0.8 cfh) for pilot flow rates
• • Dual LCD screens, 3 stage Tamper proof, and system status monitoring.
• • Front buttons or no button with removable portable remote
• • Protected from power loss by non-volitile EEPROM memory that stores lst hourly volumetric indexes, set-up configuration and calibration or settings.
• • Live flow rates to clock the meter and peak flow rates to check meter sizing
• • Optional: Independent mechanical backup index (patent pending)

Different options available:

ECM2-T
Electronically Compensate Meter with temperature compensation and ability to program a fixed factor for fixed pressure compensation.

ECM2-PTZ
Live pressure factors, live temperature factors and live super-compressibility factors.

ECM2-AT
Live pressure factors, live temperature factors and live supercompressability factors as well as full one-way communications and full audit trail compatibilities.

*Other meter sizes and styles are available upon request.
