water level sensors

1.Product overview of water level sensors

Water level sensors are specially designed for water level ranging. The module adopts FMCW mode, non-contact installation design, small size and compact structure. It has high accuracy, low power consumption and strong anti-interference ability, and is suitable for water level monitoring in lakes, rivers, flash flood warnings, reservoirs, sewage pipe networks, etc.
