Name Multi-flow nylon water meter
Brank Zysmart Water Meter
Model ZYLXSY-BV-5
Inventory 1000

一、Product Summary


Dear users, thank you for using our multi-flow nylon valve-controlled water meter. Please read this instruction manual carefully before using it, so that you can easily use our products.

Multi-flow nylon valve-controlled water meter is mainly a water inlet direction, through which water flows into the water meter movement and scours the impeller of the water meter, thus obtaining a water meter for measurement.

Implementation standard: GB/T 778-2018 "Drinking Cold Water Meter and Hot Water Meter"

CJ/T 535-2018 "Internet of Things Water Meter"

 

二、Working Principle

The working principle of the rotor-type multi-flow nylon valve-controlled water meter is that the water flow tangentially impacts the impeller from the water inlet of the watch case to make it rotate, and then continuously records the number of revolutions of the impeller through the gear reduction mechanism, thus recording the cumulative flow through the water meter.
