The meter can be calibrated for 2-inch, 2.5-inch, or 3-inch pipe. If the meter is installed in a pipe that does not match the calibration size, the compensation will be inaccurate, and process measurement will be inaccurate.
- Page 10 Planning 1.4.3 Entrained gas Entrained gas, or gas pockets, can disrupt the measurement of a fluid. A brief disruption in the signal caused by transient gas pockets can be corrected in the meter configuration, but you must avoid more frequent disruptions or serious gas entrainment to ensure accurate and reliable fluid measurement.

Page 13: Perform A Pre-Installation Meter Check
Visually inspect the meter for any physical damage. If you notice any physical damage to the meter, immediately contact Micro Motion Customer Support at flow.support@emerson.com. Connect the power wiring, and power up the meter. Remove the back transmitter housing cover to access the PWR terminals. - Page 14 Planning Figure 1-5: Power supply wiring terminals A. 24 VDC If you have an HFVM with calibration code B (viscosity and density calibration), perform a Known Density Verification (KDV) check. Use the Known Density Verification procedure to match the current meter calibration with the factory calibration.
