Details

Function Parameters Dimensions

This product is the SECK Photovoltaic Smart Remote Water Meter. This series of water meters is designed based on the traditional mechanical dry-type water meter, with the addition of an optical sensor and a smart communication module. The meter employs advanced data encoding and verification methods, ensuring high reliability in communication. It directly reads the data from the register without the need to set parameters such as the initial reading or meter constant. There is no cumulative reading error, and there is no risk of inconsistency between readings due to cumulative errors or reverse rotation of the water meter.

 

Communication can be achieved through M-BUS or RS485 bus methods to enable remote direct reading of the water usage from the water meter. This product also features valve control functionality (optional). The valve-controlled water meter can be remotely operated through management software to open or close the valve, facilitating control over water usage by the management department. This makes remote meter reading and control more convenient and reliable, saving labor and improving efficiency.

 

The optical smart remote wireless water meter, in conjunction with the intelligent meter reading system software, completes the intelligent reading of water meter data in residential areas and achieves data sharing with the settlement center through networking.
