Supplier's note

1. Technical Breakthroughs:

   • Ultrasonic Technology: Enables non-invasive, high-precision measurements without flow obstructions.
   • Wider Temperature Range: Operates reliably in extreme conditions, outperforming traditional meters limited to narrower ranges.
   • Low Power Consumption: 12VA efficiency reduces energy costs by 20% compared to conventional models.

2. Version Selection Guide:

   • Base Model (91W): Ideal for standard water applications requiring basic accuracy (e.g., municipal water distribution).
   • Advanced Model (92F): Choose for corrosive environments or higher flow rates (e.g., chemical processing plants).
   • Pro Model (93T): Best for high-pressure systems or critical applications needing ±0.2% accuracy (e.g., oil refineries or power plants).

*Enhanced accuracy vs. industry benchmarks. +15% and +30% denote improved material durability and pressure tolerance over base specifications.
