Product Description

Product Description

The LXS-15~50 series small-diameter LORAWAN wireless remote water meter is a smart meter developed to facilitate wireless remote meter reading based on the actual needs of intelligent management of water supply companies. It adopts a split design, and the electronic unit is installed in an independent fully sealed cavity. Its waterproof performance reaches IP68 level. It does not change the structure of the traditional wet or dry water meter, does not affect the measurement accuracy and sensitivity, and does not require application for the measurement frequency band (470-470- 510MHz, 868-915MHz) communicates with the collector and concentrator. The concentrator communicates with the main station through the GPRS/4G module to upload the data to the main station to realize fully automatic remote reading of water meter data and data networking with the settlement center. Shared functionality.
This type of water meter adopts a rotor dry or wet metering structure and has the characteristics of high metering accuracy, small initial flow rate, convenient meter reading, beautiful appearance, safety and hygiene, strong anti-interference ability, and long transmission distance. It can be equipped with valve control function and has the advantages of prepaid water meter.

Overload flow (Q4) - The water meter is required to meet the maximum allowable error requirements in a short period of time, and then maintain the maximum flow rate of the metering characteristics under rated operating conditions.;
Common flow rate (Q3) - the maximum flow rate under rated working conditions. Under this flow rate, the water meter should work normally and meet the maximum allowable error requirements;
Boundary flow (Q2) - the flow that occurs between the common flow Q3 and the minimum flow Q1, dividing the flow range into two areas: "high zone" and "low zone" with specific maximum allowable errors;
Minimum flow rate (Q1)-the minimum flow rate that requires the water meter's indication to comply with the maximum allowable error;
Indication error: Within the water temperature range of 0.1ºC to 50ºC, the maximum allowable error of the water meter is ±2% in the high area (Q2≤Q≤Q4) and (±5%) in the low area (Q1≤Q<Q2).
3. Working environment: water temperature 0.1~+45ºC, humidity 0~95%RH;
4. Max working pressure: ≤1.6 Mpa;
5. Pressure loss: The maximum pressure loss under rated working conditions does not exceed 0.063Mpa;

• Installation, use and maintenance methods 

1. A wireless remote water meter of appropriate caliber should be selected based on the pipe diameter and water consumption at the installation location.
2. The installation location should avoid exposure, freezing, pollution, moisture and flooding to facilitate disassembly and meter reading. During the freezing period, in addition to wrapping the water meter and water pipes, close the inlet valve of the water meter and open the outlet valve and faucet when not in use. This can prevent the water meter from being damaged due to freezing expansion. It is recommended to install it in a special water meter box.
3. The water meter should be installed horizontally, with the letter facing up and the arrow direction in the same direction as the water flow.
4. It is necessary to wash away the gravel, sediment and other debris in the newly installed pipes before installing the water meter to avoid causing water meter failure.
5. For accurate measurement, the faucet should be higher than the water meter.
6. If the water meter is installed at the boiler water inlet pipe, prevent the backflow of hot water from scalding the water meter.
7. The water meter should not be directly connected to the pipeline. The water meter and the pipeline should be connected through pipes, sealing washers, and connecting nuts. When disassembling the water meter, do not use hard plates to avoid twisting the case.
8. The water meter should be protected from excessive stress caused by pipes and fittings. If necessary, the water meter should be installed on a base or bracket.
9. Valves should be installed before and after the water meter to facilitate maintenance and replacement.
10. Do not install the water meter in a metal water meter box to avoid signal shielding and preventing remote meter reading.
