this is a product specification sheet for ecominder remote reset meters 2750rm, 2850rm, 3100rm and 3900rm
This service manual provides detailed instructions for installing, programming, and servicing Econominder remote reset water meters. It covers model-specific flow ranges, electrical requirements, and mechanical assembly procedures. The manual also includes troubleshooting steps for common issues such as no registration, no pulse, or continuous pulse, with corrective actions and part numbers for repairs.
The meters are designed for commercial and industrial water conservation, monitoring soft water service flow with mechanical impellers and timer-based regeneration control. Installation requires adherence to plumbing codes and proper orientation of the meter body and timer assembly. Programming options include immediate or delayed regeneration settings, with adjustable pulse times for delayed models.

Press and hold the red button to disengage the 24-hour gear, turn the gear to the desired time, and release the button to re-engage. To change the regeneration time, apply a new 24-hour label over the old one using the old label’s 2:00 a.m. mark as reference.
Check for defective gear box, stuck impeller, improper cable insertion, low flow, or improper installation. Use the meter checker to verify and replace components as needed.
Turn the manual regeneration knob clockwise until the Service Position Indicator dot is in the 3:00 position. This engages the program wheel and starts the reset motor. The reset time is 3 hours for delayed regeneration or 6 minutes for immediate regeneration.
