FAQ – RBCM Coriolis vs. RBVF Vortex Flow Meters

Q1: When should I choose an RBCM Coriolis meter over an RBVF Vortex meter?

A: Choose the RBCM Coriolis meter when you require high-precision mass flow and density measurement (accuracy up to ±0.1%). It is ideal for high-value liquids, chemical dosing, and slurries. Use the RBVF Vortex meter for cost-effective volumetric measurement, particularly in steam applications or large-scale water/gas lines where high precision is not the primary concern.

Q2: Is the RBVF Vortex flow meter suitable for low-flow gas applications?

A: No. Vortex meters require a minimum flow velocity to generate measurable vortices. For low-flow gas or precise gas mass measurement, we recommend our Thermal Mass Flow Meters. The RBVF series is most efficient for high-velocity steam and general industrial fluids.

Q3: Can the RBCM Coriolis meter measure density?

A: Yes. One of the primary advantages of the RBCM series is its ability to provide dual measurements: mass flow and density simultaneously, without the need for additional sensors.

Q4: Which meter is more cost-effective for steam measurement? A: The RBVF Vortex flow meter is the industry standard for steam. It is significantly more affordable than Coriolis meters and features a robust design with no moving parts, making it perfect for high-temperature steam distribution.

Q5: What maintenance is required for these meters? A: The RBVF requires minimal maintenance due to its simple bluff-body design. The RBCM, being a high-precision instrument, requires periodic calibration and inspection of the vibrating tubes to ensure long-term accuracy in critical processes.
