LEDAER LWGY Series
Liquid Turbine Flow Meter: High-Precision Measurement for Clean & Non-Conductive Fluids
📌 Overview
The Ledaer LWGY Series is a precision-engineered velocity flow meter designed for measuring the volume flow of low-viscosity, non-corrosive liquids. When fluid passes through the sensor, the kinetic energy drives the turbine rotor to rotate at a speed proportional to the flow velocity, providing highly accurate flow calculation and totalization.
✨ Key Advantages
Superior Precision
Standard accuracy of ±0.5% R or ±1.0% R, ideal for trade billing and process control.
Low-Temp Specialist
Robust performance in extreme cryogenic conditions, handling temperatures down to -200°C.
Non-Conductive Mastery
Excels in measuring non-conductive liquids like oils and alcohols where electromagnetic meters fail.
Wide Turndown Ratio
Standard 1:10 to 1:20 rangeability ensures accurate readings even at lower flow velocities.
