I. Overview.
Lora wireless remote water meter is a self-developed remote water meter for remote meter reading and control in response to the actual needs of intelligent management of water supply companies. It uses a mechanical water meter as the measurement basis, communicates with the collector concentrator through the micro-power application-free measurement frequency band (470~510MHz), uploads the data to the concentrator, and the concentrator communicates with the master station through the Lora module to upload the data to the concentrator. The main station realizes the automatic remote meter reading of the water used by the water meter, supports two-way communication, can switch valves in real-time, and read in real-time. The meter end is normally in low power consumption mode. When the concentrator issues a meter reading command, the water meter at the specified address wakes up, to read the meter, and continues to enter the low power consumption after the completion, effectively reducing the power consumption of the meter end. This product also has a valve control function (optional), which is convenient for the management department to control the water consumption of the water meter, making remote meter reading and control more convenient and reliable, while saving manpower, material, and financial resources, and effectively improving production efficiency.
II. Performance characteristics
1. This product is based on our very mature and stable direct-reading water meter, with high reading accuracy;
2. This product is equipped with a through-hole ball as a valve at the water outlet of the meter body to reduce the influence of the valve on the measurement. This function is optional;
3. The electronic reading device does not affect the measurement accuracy of the original primary meter.
4. This product adopts an IP68 protection design so that all electrical components such as circuit boards, power supply batteries, and actuator motors are entirely isolated from the outside atmosphere.
III. Functions of main components
1. Lora wireless motherboard: mainly used to store Lora wireless motherboard;
2. Power supply battery: mainly used to store the battery for easy disassembly;
3. Photoelectric direct reading sampling module: mainly used for sampling metering data;
4. Base meter: mainly used to measure the current water consumption;
5. Through-hole ball valve (optional): It is mainly used to control the closing and opening of the tap water flowing through the meter under the control of the main circuit board.

VI. Installation
(1) Before installing the Lora wireless remote water meter, it is first necessary to read and record the address of the meter to ensure that the electronic code in the meter is consistent with the serial number of the dial;
(2) The installation of the Lora wireless remote water meter must meet the installation requirements of GB/T778.2.
(3) The caliber of the Lora wireless remote water meter should be determined according to the caliber of the installation pipe and the frequently used flow rate is less than or close to the standard flow rate of the Lora wireless remote water meter, and the installation location should be convenient for disassembly and reading.
(4) The Lora wireless remote water meter must be installed horizontally, the direction of water flow is consistent with the direction indicated by the arrow and the display of the reading dial on the meter head is guaranteed to face upward.
(5) Before installing a new Lora wireless remote water meter, remove sand, gravel, hemp, and other debris in the pipeline to avoid water meter failure.
Put the meter joint into the joint nut and install it on the pipe, then twist the joint nut to install the Lora wireless remote water meter on the pipe, keep the reading dial of the Lora wireless remote water meter horizontally upward, and the water meter should not be subjected to excessive force when connecting to the pipe. Bending force, so as not to damage the interface of the Lora wireless remote water meter.
VII. Matters needing attention
(1) Regularly check the operation of the Lora wireless remote water meter, and pay attention to antifreeze in winter.
(2) The installation location should avoid exposure, freezing, pollution, humidity, and flooding, so as to facilitate disassembly and meter reading. The water discharge valve and the faucet are opened to prevent the water meter from being damaged due to freezing and expansion. It is recommended to install it in a dedicated water meter box.
(3) If the remote meter reading data of the Lora wireless remote water meter does not match the character wheel or the remote transmission system of the Lora wireless remote water meter fails, the reading of the dial wheel on the meter head shall prevail.
