Description

Wireless remote transmission valve-controlled cold water meter is used for measuring the total volume of water flowing through the tap water pipeline. This new water meter adopts new technology, has novel design, reasonable design, excellent material selection, beautiful appearance, precise assembly and convenient maintenance.This series of wireless remote valve controlled cold water meter is in the mature mechanical cold water meter on the basis of the increase of electronic automatic sampling count, data wireless transmission, remote valve control and other functions, to facilitate the management of remote monitoring and management departments.

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.LORA spread spectrum wireless communication technology is adopted to ensure the normal transmission of data due to its wide signal coverage.
5.Battery compartment with convenient battery replacement for on-site battery replacement.
6.Support real-time data communication for remote monitoring and management.
7.Protection level: IP68

Installation and maintenance

1. Choose the diameter of water meter, should be decided according to pipe and use flow rate, and unfavorable use hot water
2. Installation location should avoid exposure, freezing, pollution and water flooding, so as to disassemble and read the meter
3. Horizontal water meter installed horizontally, so that literally up, and make the arrow on the case and flow direction the same
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. To measure correctly, the tap should be higher than the meter
6. 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
7. Do not put anything on the top of the meter.Pay attention to moisture-proof and strictly prohibit water droplets from infiltrating into the water meter controller to damage the control system and affect the normal use of users
