The runoff sediment automatic monitoring device is an intelligent device designed specifically for monitoring soil erosion, river sediment research, and water conservancy engineering safety assessment. It collects real-time data on runoff, sediment content, flow velocity, etc. through multi parameter sensors (laser scattering, acoustic Doppler, pressure sensing, etc.), and combines AI algorithms to achieve dynamic prediction and early warning of sediment changes.

IV. Product dimensions and working schematic diagram

5. Maintenance and Care
Before the first use, please loosen the transport fixing rod, otherwise the equipment will not work normally.
Before the first use or after a long period of non-use, please re-calibrate with clean water and zero calibration.
Check the water tank regularly, if there is a large amount of sludge deposition or foreign objects, please clear them, and the drain valve can be removed and washed.
Check the drain valve, sample bucket water inlet valve, sample bucket drain valve regularly to see if the water flow is unobstructed. If the water flow is weak or no water, you can cancel the control line on the drain valve and disassemble the drain valve for cleaning, and then re-install it.
Keep the interior of the equipment clean, and it is forbidden to pile up items in the weighing part, and it is forbidden to place items under the sample bucket.
When the temperature in the area where the equipment is located drops to zero degrees or lower, please drain the water inside the equipment to avoid ice damage to the equipment.
When the sensor has been used for a long time and there is a measurement error, it can be calibrated and corrected by cooperating with the instrument. When the above methods for maintaining and calibrating the sensor still cannot be calibrated and measured, it indicates that the sensor is damaged.
