Model: LXSK-15-40, LXLK-50-300 water meter2. Size: DN15-DN300 (DN50~DN300, please check bulk water meter)3.Body: Brass/Nylon/stainless steel4.Type: Dry dial/wet dial (standard)5. Max work pressure: PN16.6. Protection class: IP687. Pressure loss: ≤0.063Mpa8. Water temperature: T30, T909. Standards: ISO4064 Class B10. Certificate: MID11.Software: free for clients12. Composition: Computer/Network, smart card, card reader.INSTRUCTIONS FOR USE:1. Users pre-purchase water volume with the smart card from the water management department.2.
