2、 Performance parameter benchmarking
| parameter | Pressure type water level gauge | Radar water level gauge | Ultrasonic water level gauge |
| precision | ± 0.1% FS (typical value) | ±3mm | 0.2%~0.5%FS |
| environmental adaptability | Strong (corrosion-resistant/turbid water) | Medium (afraid of fog and dust) | Weak (afraid of turbulence foam) |
| Installation complexity | Low (investment based) | High (requires fixed bracket) | Chinese |
| cost | Low to medium | high | Chinese |
Note: Pressure type is cost-effective in scenarios with low sediment concentration and gentle flow velocityBetter; Radar is suitable for high-precision demand reservoirs

.
Selection warning：
- Use with caution in scenarios where the sediment content is greater than 5% or the flow rate is greater than 3m/s (which can easily clog the membrane)；
- Deep well measurement requires the configuration of a gas pipeline to balance the air pressure8.
The pressure type water level gauge is evolving from a single measurement tool to a core sensing node of smart water management, and its technological iteration continues to promote the digitalization process of water conservancy, environmental protection, and urban infrastructure.
