LC Digital Oval Gear Flow Meter

LC series oval gear flow meter is a direct reading accumulative meter. It is a volumetric Flow meter that measures the summation of liquid flow through the pipeline. Can be widely used in petroleum, chemical, medical and health departments of the flow measurement.



Instrument characteristics

▪High accuracy, wide flow range and good repeatability;

▪The spiral rotor has uniform rotation, small vibration and long life;

▪It is not sensitive to the change of the viscosity of the tested liquid, especially suitable for the measurement of the liquid with higher viscosity;

▪Simple structure, small size and light weight;

▪Easy to install, no straight pipe segments need to be installed before the table.
