DN4 or DN6? Choosing the Appropriate Flow Meter for 45–250 L/h
A Small Flow Rate Requires the Right Meter
Need to measure water flow between 45 and 250 L/h? Choosing the wrong flow meter size could leave part of your required measuring range uncovered.
For low-flow applications, the key is matching the meter to your flow rate, accuracy, pressure, and temperature requirements.
DN4 vs. DN6: Which Is Better?
Consider this application:
Medium: Water
Flow rate: 45–250 L/h
Accuracy: 1%
Material: 304 stainless steel
Temperature: Up to 60°C
Pressure: Up to 1.6 MPa
Configuration: Meter body only, without display or cables
| Model | Stated Flow Range | Suitability |
|---|---|---|
| DN4 | 40–250 L/h | Better match |
| DN6 | 100–600 L/h | May not cover the minimum flow |
Our preliminary recommendation: Evaluate DN4 first. Its stated measuring range covers the required 45–250 L/h, while DN6 starts at 100 L/h.
Before ordering, confirm the model's accuracy across the required range, pressure rating, temperature limits, and connection compatibility.
