The WT-SFM-FM flow turbine from STAUFF Diagtronics is designed for versatile use, either as test equipment or permanently installed in pipelines. It measures oil flow by rotating an internal axial turbine, generating a pulse output that can be read by devices like the DHCR, DHT, or HT series testers. Equipped with a thermistor bead, it also provides temperature data. This turbine can measure bidirectional flow accurately when installed with 8 to 10 diameters of straight conductor on the inlet side and straight fittings. It may come with or without a pressure balance loading valve, protected by rupture discs, allowing system performance observation under load.
