Usage

LORA Remote reading Water Meter It is used to measure and control the water flow rate through pipe .The meter has the characteristics of high reliability, high accuracy and low power consumption. All parameters meet the requirements of national standard (GB/T778.1-3-2007) and urban construction industry standard (CJ/T133-2007). 

Installation

1. The caliber of water meter shall be based on the size of the pipeline and the usual used water flow is no more than common flow of the water meter; and the installation location shall be avoided insulation , flooding, freezing and pollution, and convenient for installation, removing and reading data. 
2. The sands and stones and other sundries in the pipeline, such as hemp thread shall be cleaned firstly in Case of water meter breakdown. 
3. Please leave enough space for repairing, and installation according to water flow direction on the pipe and should be installed horizontally. 
4. Please do not apply too much force when Connecting the water meter and pipe, to avoid damaging the meter body and leakage. 
5.If the water meter is installed on the inlet of the boiler, shall install check valve on the outlet of water to prevent the return current of hot water and steam from damaging the water meter.

Transportation and storage

1. The transport of the water meter should not be severely impacted. The water meter should be kept in the original package, and the ambient temperature is 0 -60, the relative humidity is less than 95%, and there is no corrosive gas in the air.
2. The water meter is stored in the warehouse, and the height of the stack is not more than 10 cases. The height of the water meter is not more than 10. The water meter unpacked by the single package is not suitable for storage.

Note

1.The water meter should be far away from high temperature, high humidity and high magnetic environment
2.Don’t hide with metal objects, according to the specifications.
3.It’s strictly forbidden to dismantle the table privately, otherwise the consequences will be conceited.
