LoRa Smart Water Meter DN15~25mm For Residential

The wireless remote water meter can automatically upload the readings of the water meter to the management platform, and the administrator can also send instructions on the platform to control the opening/closing of the water meter valve. It can greatly simplify the charging process in this era of increasing labor costs, and even paperless online charging can be realized.

 

 

• The whole circuit board uses ultra low power consumption design, powered by high high-capacity lithium battery, and battery life of at least 6 years.
• The module uses a deep dormancy time design that can completely close the wireless module during the deep dormancy period ( not in operation during night time), which drastically helps to reduce power dissipation.
• Module with automatic data storage function when powered down and up, which assures the data won't be lost when powered down.
• The joint of the RF module and the base meter uses the integrated structure with a built-in antenna, which reduces the damage of the antenna.
• AMI function that supports the system can control valve opening or closing in real-time.
• With an anti-magnetic interference function.
• With the battery voltage detection function;
• Support data docking with the Client's management platforms
