Key features and selection tips
Advantages: Ultrasonic non-contact measurement, no wear, no blockage, no pressure drop, suitable for clean liquids; fast response, suitable for dynamic flow monitoring; easy installation, no pipe breaking required, low maintenance cost.
Limitations: Measurement accuracy will decrease for high-bubble, high-suspended solid liquids; ensure the inner wall of the pipeline is clean and free of severe scaling; not suitable for high-temperature, high-pressure, and highly corrosive liquids (requires special protection).
Selection suggestions: Choose the appropriate model based on the liquid type; select 4–20 mA current output model for remote monitoring scenarios; additional protection is required for outdoor / high-humidity environments.
