Description
ELEMER-RV vortex flow meters measure and continuously convert the volumetric flow and volume of gaseous media (natural and associated petroleum gas, air, oxygen), steam and liquids into unified output signals. Available in standard and insertion versions for large-diameter pipelines.
Nominal diameter range is DN 25-300 mm, operating pressure up to 25 MPa, media temperature -50...+350 °C. Measurement accuracy is up to ±0.5% for liquids and ±0.9% for gases. Design variants include compact (monoblock) or remote installation, flanged or wafer mounting, and a removable flow body for maintenance and verification without removing the meter from the pipeline.
