No, routine calibration is not required for either the M5000 or the E-Series. Both are factory-calibrated to traceable standards and designed for long-term accuracy without recalibration under normal use. These meters are widely accepted in regulated municipal and utility applications and meet AWWA and NSF/ANSI/CAN standards.
M5000 - Electromagnetic
- Calibrated at the factory with traceable certification
- Calibration values are digitally stored and stable for the life of the meter
- No recalibration needed unless the electronics are replaced
E-Series G2® – Ultrasonic
- Solid-state, no moving parts – minimizes wear and drift
- Factory-tested for accuracy; no field calibration required
- Optional test ports available for verification, if needed
Both meters are suitable for use without mandated calibration intervals. Calibration certificates are available upon request.
