It is suitable for water metering in the situation of large flow change.
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.
Installation requirements
Installation requirements
·It must be installed horizontally with the head upward
·Measurement with full pipe
·Straight pipe section with three times of pipe diameter in front of the table is required
