Product Features
◎Detachable movement structure, easy to maintain.
◎Wide range, suitable for the occasion of large flow change.
◎Copper sealed counter, IP68 waterproof grade, to prevent surface fogging
◎Internal adjustment structure can effectively prevent the meter from being adjusted without permission.
◎The high wear resistance bearing system ensures the stability and reliability of the product, and can obviously improve the maximum flow.
◎Adopt the industry advanced thermal spraying process to maximize the corrosion resistance of the case and extend the service life.
◎It can be equipped with non-magnetic sensor electromechanical conversion module, with RS-485 or M-BUS standard interface.
