[Case Study] Factory Water Intake - Introduction of Radio Wave Water Level Gauge

[Case Study] Factory Water Intake - Introduction of Radio Wave Water Level Gauge

Which water level gauge is best for the factory's intake?

Driftwood and fallen leaves flow into the water intake, causing blockages in the screens and waterways. Furthermore, temperature differences and the effects of wind and snow can lead to unstable water level measurements. The water intake is an inconspicuous facility, but if problems arise, they can affect the entire production line. So, what kind of water level gauge is suitable for such an environment? For more details, please refer to the related URL.
