Vertical Woltman Dry Type Cold Water Meter Class C/R160/R200 
WS2 is a dry type vertical woltman type, designed to measure the total volume of unidirectional water passing through large pipeline in sizes of 50mm to 200mm, such as tap water, well water, river water, as well as sewage, except corrosive water.
Features
* It is a vertical woltman water meter.
* Magnetic drive, lower transmission resistance.
* Magnetic shield, for external magnetic field protection.
* Removable structure, easy maintenance.
* Evacuated and sealed dry dial register and big digits ensures clear reading, long working life.
* The measuring mechanism can be removable from the body for checking, maintaining and replacing, and the body needn't be dismantled from the pipeline.
