A TF1100-DC dual channel ultrasonic flow meter can provide reliable industrial flow measurement when the application and installation conditions are suitable. However, actual measurement accuracy depends on several factors beyond the flow meter itself.
Understanding these factors helps users improve measurement reliability and avoid unnecessary troubleshooting.
Incorrect pipe diameter or wall thickness affects the calculation of liquid flow rate and ultrasonic signal travel time. Measure the actual pipe dimensions rather than relying only on nominal pipe size.
Pumps, elbows, tees, and control valves can create turbulence. Allow approximately 10D upstream and 5D downstream of the measurement point where conditions permit.
Transit-time meters are for liquids allowing reliable transmission. Excessive bubbles or suspended solids may reduce signal quality and measurement reliability.
Incorrect spacing or poor coupling causes errors. Follow installation instructions and verify the calculated mounting distance before securing transducers.
At low velocities, transit-time difference becomes smaller. Check the specified measuring range and accuracy conditions when selecting for low-flow applications.
☑ How Can You Improve Measurement Accuracy?
- • Verify the actual pipe dimensions.
- • Select compatible transducers.
- • Ensure proper acoustic coupling.
- • Choose a suitable installation location.
- • Confirm that the liquid and pipe conditions meet the instrument requirements.
- • Compare readings with a suitable reference instrument when necessary.
Reliable ultrasonic flow measurement depends on correct instrument selection, accurate pipe parameters, suitable installation, and stable signal transmission.
For the TF1100-DC, confirm the applicable accuracy specifications and operating conditions with Lanry Instruments before using the measurement results for critical process control.
