HF Range-Flow Meters
High Flow Positive Displacement Meter
- 0 – 60 L/min covered by 3 internals: HF20, 40 and 60
- High Pressure Capability
- Accuracy: ± 1.0%
- Range of material options
The HF range started in 1998 with the HF20 using a graphite rotor rated to 20 l/min. The HF40 and 60 were added to double and triple the flow range up to 40 and 60 litres per minute. Materials now include stainless steel and titanium.
