Dall Tube Flow Meter Calculation
Dall tube flow meters are crucial in measuring liquid flow rates in various industries. Accurate calculation ensures efficient processes and cost savings.
- Enter the dall tube’s diameter in millimeters.
- Enter the flow rate in liters per minute.
- Enter the liquid’s density in kilograms per liter.
- Click ‘Calculate’.
The calculation uses the formula: Flow = π * (Diameter/2)^2 * Density * 9.81.
| Diameter (mm) | Flow (L/min) | Density (kg/L) | Result (kg/s) |
|---|---|---|---|
| 20 | 50 | 1 | 0.49 |
| 30 | 80 | 1.2 | 0.85 |
| 40 | 120 | 1.5 | 1.26 |
| Diameter (mm) | Flow (L/min) | Density (kg/L) | Result (kg/s) |
|---|---|---|---|
| 20 | 50 | 1 | 0.49 |
| 30 | 80 | 1.2 | 0.85 |
| 40 | 120 | 1.5 | 1.26 |
- Always use the correct unit for density (kg/L).
- Ensure the dall tube is clean and undamaged for accurate readings.
- Regularly calibrate your dall tube flow meter.
What if my flow rate is in GPM?
Convert GPM to L/min using the conversion factor 0.264172.
Can I use this calculator for gas flow?
No, this calculator is for liquid flow only.
