Benefits
Built for reliable measurement of clean liquids, the SLW Series Liquid Turbine Flow Meter operates by converting fluid velocity into the rotational speed of a precision-machined rotor. As the liquid flows through the meter body, the rotor spins proportionally to the flow rate, and this rotational motion is sensed and converted into a pulse, frequency, or optional 4–20 mA signal. This simple yet highly accurate principle allows the meter to achieve excellent repeatability and fast response.
The stainless-steel construction (304 or optional 316) ensures durability and compatibility with a wide range of process fluids. Designed for low-viscosity media, the meter is commonly applied in water distribution, fuel measurement, oil monitoring, batching systems, and general industrial fluid management. Its threaded process connections and compact footprint make it ideal for retrofits, skid systems, and small-diameter pipelines.
With a turn-down ratio typically greater than 10:1, high accuracy options (±0.5% to ±1.0% of reading), and optional digital output formats, the turbine meter integrates easily with PLCs, controllers, and automated dispensing systems. For best performance, installation in straight pipe runs with minimal flow disturbance is recommended, and the meter is not suited for liquids containing high particulates or for high-viscosity applications.
