Product Description

Wireless meter reading, remote management, ladder water price, prepayment, Internet of things nb-iot technology, lower power consumption, mass connection, stable and reliable data transmission
It is applicable to the measurement of tap water flow in smart city, smart water service, smart community, residential, commercial, industrial park and other properties;Combine with software to build remote meter reading management system
Seamless access to multi-meter integration (electricity, water, gas and heat) intelligent management system, to achieve intelligent energy management of the Internet of things

Description
Wireless remote transmission valve-controlled cold water meter is an intelligent Internet of things water meter with electronic automatic sampling count, wireless data remote transmission of Internet of things (nb-iot), remote valve-controlled and other functions for measuring the total volume of water flowing through tap water pipelines.

Features
1.Anti-theft water function: when there is strong magnetic interference metering signal, the water meter automatically closes the valve until the strong magnetic disappear, to prevent the use of strong magnetic water theft.
2.Under voltage prompt function: when the built-in battery voltage is insufficient, the automatic reporting system prompts for timely battery replacement.
3.Anti-rust dead valve function: automatic switch valve twice a month to prevent the valve from rust dead phenomenon caused by long time action, improve the stability of operation.
4.Internet of things(NB-IoT) wireless communication technology, signal coverage is wide, can ensure the normal transmission of data.
5.Battery compartment with convenient battery replacement for on-site battery replacement.
6.Protection level: IP68

Installation and maintenance

1.The diameter of the water meter is selected according to the pipe and the flow rate. The product cannot be used for hot water measurement in hot water pipes.
2.Installation location should avoid exposure to the sun, ice, pollution and water flooding, so as to disassemble and read the meter;
3.According to the case side arrow pointing to the direction of horizontal installation of water flow, and make the head literally up, the installation height should be lower than the height of the tap;
4.The newly installed pipe must be cleaned of stones, silt, hemp and other sundries in the pipe before the water meter can be installed to avoid the use of water meter fault;
5.Water meter and pipe should be connected by connecting pipe, sealing washer, connecting nut, do not violently disassemble and install, to avoid human damage to the normal use of water meter;
