KM07-03
The ultrasonic remote water meter is a flow sensor combined with a microprocessor and adopts advanced ultrasonic measurement technology to accurately and reliably measure water consumption for commercial and industrial applications. Long lifespan, complete output communication functions, to meet all kinds of communication and wireless networking requirements, with small flow detection capabilities.
Description
1. Features
● AMR-ready remote system for wireless, RS485, M-bUS or wired communication modes, convenient to manage user's water consumption.
● No mechanical moving parts, low initial flow rate, poor available water quality, wide range ratio (R400), IP68.
● High level of precision and better stability.
● For both hot and cold water.
● detect forward and reverse flow.
● Digital display (8-year battery).
● Without air measurement.
● Provided with a lead seal.
● Environment EB,E1.
