Coriolis Flow Meter Expertise
To ensure that your Coriolis flow meter keeps functioning within optimal parameters and maintains accurate flow rate measurement we’ve gathered some best practice tips based on our years of experience as well as input from our customers.
- Select only Coriolis flow meter sensor material that is chemically compatible with all expected process fluids and cleaning/flushing agents.
- Orient the flow meter properly to keep the meter full and avoid two-phase conditions. For liquids: tubes down or flag position flowing up. For gases: tubes up or flag position flowing down.
- Size the Coriolis meter properly to maintain best measurement performance across the full process flow range within acceptable pressure loss range.
- Insulate and/or heat-trace the Coriolis flow meter for best density, concentration, and volume measurement performance, or if temperature change will cause undesirable effects such as flashing, condensation, or freezing.
- Verify that the calibration constants from the mass flow sensor are reflected properly in the electronics.
- Locate all control valves downstream of the Coriolis meter to provide backpressure (and to keep the tubes full).
- Perform a zero calibration if the normal process temperatures or pressure is far from the manufacturer’s calibration conditions. Circulate fluid at process pressure until all flow meter components are brought to thermal equilibrium, then block the meter in with no flow, and zero the meter.
- Determine a field baseline for the tube integrity diagnostic test values (aka Meter Verification) if required by the manufacturer.
