Introduction

LXLC Spiral water meter is with detachable structure, easy to repair and maintenance. It is suitable for measurement of water with poor quality. Indicator adopts magnetic drive mechanism, thus displaying clear and intuitive readings (a liquid-sealed type of the counter part is optional for users). The meter is equipped with sensors, so it can also be used as a base table for the large-caliber IC card smart meter. When the calibre and movement of the water meter are replaced, there is no need to cut off the water supply. It is with strong commonality, small pressure loss, as well as long life.
