1. Product introduction

The device featuring battery-powered, ultra-low power consumption, IP68-rated and wireless communication. Suitable for monitoring sites with no power supply availability and in harsh environments (e.g., pipeline or manholes), and it can be measured for both full-pipe and non-full-pipe.
Users can view real-time monitoring data via the device's high-definition LCD screen, while the wireless communication capability enables remote data monitoring through a cloud-based platform. Operating on battery power, the device features easy installation, extended battery lifespan, and stable operation.

2. Functions

2.1 Data sampling

The device is capable of automatically collecting flow velocity, water level and flow rate, periodically transmitting the data to the flow monitoring system platform via wireless communication,with additional device status reporting including battery level, system parameters, and signal strength.

2.2 Parameter configuration

Parameter configurations can be deployed according to operational requirements. For specific data fields, refer to the "Configuration Data" section in Appendix

2.3 External wake-up

During on-site debugging, when manual data reporting or data viewing is required, swipe a magnet over the upper-right corner of the screen to wake up the device for data sampling. This action will simultaneously update the display panel content and trigger data reporting.

2.4 Data breakpoint resume

The manhole water level monitor employs an intelligent design with a high-capacity buffer

and dynamic partitioning technology. It stores data during network outages and automatically uploads the retained data when communication resumes, ensuring continuity of monitoring system data.

2.5 Remote operation and maintenance

The device can be integrated with a remote O&M platform, enabling remote operation and maintenance of the device with full-process status monitoring, ensure the device uninterrupted normal operation

3. Installation Instructions

3.1 Installation Preparation

Prior to equipment installation, ensure all required materials and accessories are prepared, including drill bits, magnets, mounting brackets, hand-held drills, and angle grinders.

3.2 Installation & Commissioning

For detailed commissioning procedures, reference may be made to the Equipment Installation Implementation Plan. To obtain this document, please contact the designated sales representative
