The wireless photoelectric direct reading valve control water meter can realize remote wireless valve control function and meter reading function.

Technology:
1. we can measure the positive and negative flow rate of the water meter, provide decision-making reference for the management department and prevent users from stealing water.
2.,we can achieve the price of ladder water, and facilitate the management department to collect fees according to the price of ladder water.
3.In order to ensure the service life and accurate reading of the sensor, the Holzer effect sensor is used in the wireless remote water meter. In the circuit design,It ensures that the mechanical degree of the water meter is consistent with the electronic readings.

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.
4.Our company will optimize products according to the situation every year, and we can't inform customers one by one. Our company has the right of final interpretation of product functions.
5.If you have any problem, please connect us, we will solve it as soon as possible. Thank you.
