Road Area Water Meter KNF-132

This device adopts a hidden buried installation method, which meets the current urban landscape requirements. The dual-mode (ultrasonic and conductivity) working mode can effectively solve the product problemThe battery life issue is addressed by utilizing internal intelligent algorithms to automatically switch measurement modes, effectively reducing product power consumption. Conductivity and ultrasonic measurement methods are used to sense changes in water level. Due to the special nature of water on the road surface, most of the time the equipment is installed in an anhydrous state. Therefore, directly measuring with a single ultrasonic signal is wasteful of electricity and has a significant impact on the battery life of the product. Therefore, four electrodes (mutually backed up) are introduced to measure the conductivity of water using the electrodes to determine whether there is water. Since the power consumption of measuring conductivity is extremely low, this can greatly improve the utilization rate of the battery. When water is measured, the device will automatically switch to ultrasonic measurement mode. Of course, in order to ensure the reliability of the work, ultrasound will also be regularly activated to perform composite judgment on the conductivity measurement results.

The unique wave control technology optimizes the blind spots of the product in ultrasonic measurement mode. The echo pattern measured by the equipment can be reproduced and analyzed through a dedicated interface.
Determine the current water level by observing the changes in the propagation time of ultrasonic waves in water. It should be noted that the product may be affected by ultrasonic measurement blind spots, and the water level and environmental temperature signals will be uploaded to the cloud through NB-IO. It is more suitable for use in situations where the water level is not high (usually below 0.5 meters of accumulated water), such as open roads, bridges, elevated roads, parks, etc. (installation) for water level measurement.
