Turbine Flow Meters Stainless Steel
RTLWGY Stainless Steel Turbine Flow Meter
The RTLWGY stainless steel turbine flow meter is a precision instrument engineered for accurate and repeatable
measurement of liquid flow in industrial applications. Built with a 304 stainless steel housing and a
tungsten carbide rotor shaft, it provides long-term stability and corrosion resistance in demanding process
conditions. A compact threaded design and IP65 protection make it a reliable choice for water, oils, and
low-viscosity chemicals across diverse sectors.
Operating on the turbine principle, the device converts the rotor’s speed into a proportional pulse signal
for precise digital measurement. Optional 4–20 mA output supports integration with PLC/SCADA and process
control systems. For a broader view of our portfolio, visit the

Working Principle
As liquid passes through the meter, it spins a balanced turbine rotor at a speed proportional to the flow rate. A pickup
sensor detects the rotor’s motion and generates a frequency signal that the transmitter converts to engineering units.
The result is stable, real-time flow measurement with excellent repeatability.
Installation and Maintenance
The meter can be installed horizontally or vertically provided the pipe remains completely filled. For best accuracy,
include sufficient straight lengths upstream and downstream and ensure clean media. Maintenance is limited to periodic
inspection and cleaning of the rotor and sensor in applications where deposits may form.
