Product Description

Liquid Turbine Flow Meter

LWG-N1 series              LWG-N2&A series       LWG-E series

                             




Operating Principle
Fluid entering the meter first passes through an inlet flow straightener that reduces its turbulent flow pattern. Fluid then passes through the turbine, causing the turbine to rotate at a speed proportional to fluid velocity. As each turbine blade passes through the magnetic field generated by the meter's magnetic pickup, an AC voltage pulse is generated. These pulses provide an output frequency that is proportional to volumetric flow.

Technical Data
-Output: Pulse/4-20mA
-Accuracy:±1.0 of Rate / ±0.5% of Rate
-Operating Temp.:-20.....+60ºC
-Fluid Temp.:-20.....+150ºC
-Body Material:SS304/SS316
-Rotor Material:2Cr13/CD4MCu
-Bearing Material:Turgsten Carbide

Description
The liquid turbine flow meter in the series LWG are specially designed for usage in water, diesel, gasoline and other fluid measurement and control systems.They operate according to the turbine principle, i.e. the speed of an impeller turning in the fluid flow is measured and converted into pulse or 4-20mA signals.
