Buying Guide
Inline ultrasonic flow meters come in various configurations. When selecting a model, consider:
- Pipe size and installation method: inline, wall-mounted, insertion, or clamp-on transducers. Ensure compatibility with your pipe diameter (DN32–DN6000 mm is common in these options).
- Liquid compatibility: most units handle water, seawater, sewage, oil, and alcohol. Verify media clarity and the presence of particulates that could affect ultrasound transmission.
- Measurement direction and outputs: bidirectional flow capability is valuable for detecting reverse flow. Look for 4-20 mA, pulse, and relay outputs to integrate with control systems and SCADA.
- Power and interfaces: check voltage ranges (DC and AC options) and communication protocols (RS485/MODBUS or similar) for compatibility with existing infrastructure.
- Durability and environmental rating: IP67/IP68 protection supports outdoor and harsh environments; consider operating temperature ranges for your application.
- Data storage and software: built-in SD cards and downloadable data can aid compliance, diagnostics, and historical analysis.
- Maintenance and installation impact: clamp-on or inline sensors reduce downtime. Some kits include multiple transducers and accessories for flexible deployment.
- Accuracy and repeatability: typical figures approach 1% with high-quality chips; assess required precision for regulatory or process control needs.
For oil, chemical, or high-temperature service, verify transducer material compatibility and temperature limits. In water treatment and municipal applications, ensure bidirectional capability and data logging meet reporting requirements. Evaluate total cost of ownership including sensors, cables, power, and potential maintenance needs across the system lifecycle.
