  • Page 8: Other Installation Considerations

    Calibration boundaries Important Micro Motion calibrates all meters at the factory according to the sensor calibration range selected at point of purchase. The factory calibration process takes into account the potential boundary effect of the planned installation. At point of installation, confirm that the meter calibration range and boundary matches the planned installation to ensure optimum performance of the meter.
