Standard flow meters often fail in specialized small pipe applications, costing companies thousands in inaccurate measurements and downtime. Custom ultrasonic solutions solve these precision challenges.
Customized ultrasonic flow meters for small pipes (6-50mm) overcome 3 key limitations: 1) They handle difficult fluids using specialized transducers (PVDF for chemicals, PEEK for high temps), 2) Adapt to space constraints with compact housings, and 3) Achieve ±0.25% accuracy through calibrated measurement paths tailored to pipe geometry. These modifications cost 15-30% more but improve performance by 40-60%.
Customized Ultrasonic Design
The true value emerges when standard meters can’t meet application demands. Here’s how customized solutions bridge the gap.
What Are the Disadvantages of an Ultrasonic Flow Meter?
Seven challenges that customization solves:
Standard vs. Customized Performance
| Limitation | Standard Meter Issue | Custom Solution |
|---|---|---|
| Dirty Liquids | Signal attenuation | High-power 2MHz transducers |
| Pulsating Flow | Measurement errors | Advanced DSP algorithms |
| Small Pipe Vibration | Noise interference | Vibration-damped mounting |
| High-Temperature Steam | Transducer failure | Ceramic sensors (250°C rated) |
| Low Flow Rates | Detection failure | Optimized beam angles |
| Non-Circular Pipes | Accuracy drift | Path geometry compensation |
| Mixed-Phase Flow | Incorrect readings | Multi-frequency discrimination |
