Buying Guide
What to consider when choosing an ultrasonic flow meter
- Pipe size and mounting style: Verify DN ranges and whether you need clamp-on, inline, wall-mounted, or insertion methods for your environment.
- Medium compatibility: Check if the meter supports liquids you measure (water, seawater, fuels, alcohol, oils, etc.) and temperature ranges.
- Measurement accuracy and stability: Look for explicit linearity, repeatability, and response time figures relevant to your process.
- Output and integration: Determine required data interfaces (RS232, 4-20mA, pulse, relays) and whether you need onboard logging or software for data export.
- Power and installation conditions: Assess voltage requirements, portability needs, and whether the device is suited for outdoor or hazardous areas.
- Maintenance and calibration: Consider whether onsite calibration is available and how often recalibration might be needed.
Which features matter most by buyer type
- Field technicians: Prioritize handheld units with easy setup, wide pipe ranges, and simple data export.
- Industrial plants: Look for meters with robust signaling options, multiple transducers, and strong corrosion resistance.
- Researchers and labs: Favor meters with precise data logging, high accuracy, and flexible units for diverse experiments.
Quick tips for installation and use
- Plan sensor placement to avoid strong vibrations and ensure a stable signal through the pipe wall.
- Calibrate with representative test liquids if onsite calibration is available, especially when using non-standard media.
- Verify data logging and export workflows before deployment to ensure seamless integration with your SCADA or analytics systems.
