Turbine flow meter

LWGY series turbine flow meter is a new generation of turbine flow meter learned from advanced technology at home and abroad and went by optimal design with features of simple structure, lightweight,high accuracy,good repeatability,responsive,convenient installation and maintain etc.

Features
1.High accuracy,generally ±1%R,±0.5%R,higher accuracy ±0.5%R available
2.Good repeatability, short-term repeatability 0.05%~0.2%,available to get high accuracy for regular and
online calibration,priority selection in trade settlement.
3.Pulse frequency signal output,available for overall calculation and computer connection without zero
drift,strong anti-interference.
4.Compact and light structure,convenient maintain,high flow capacity.
5.Insertion type,used for large pipeline size measurement,low pressure loss,cheap price,available to take out without flow cutoff.
