Flow Meters
Turbine Flowmeter
A flanged turbine flowmeter that measures by average flow velocity on the Woltmann impeller principle, suited to low- and medium‑viscosity liquids.
Product Overview
This flanged turbine flowmeter measures flow by average velocity on the Woltmann impeller counting principle. It is suitable for low- to medium‑viscosity liquids such as water, emulsions, glycol mixtures and light oils. Built with corrosion‑resistant high‑grade steels and tungsten carbide bearings, it offers high accuracy and long service life. Accuracy is ±1% (±0.5% optional) with repeatability of ±0.05%, nominal sizes range from DN15 to DN150 and medium temperature from -60 to +350 °C. Intrinsically safe explosion‑proof versions (ATEX/IECEx/CSA) are available. Applications include metering, monitoring, blending and batching.
