LF Range-Flow Meters
Low Flow Positive Displacement Meter
- 0 – 90 L/Hr covered by 3 internals: LF03, LF05 and LF15
- High Pressure Capability
- Accuracy: ± 1.0%
- Range of material options
The LF (or Low Flow) meters are the smallest in the VFF range. LF15 was introduced as our smallest meter in 2003 and was originally rated to 1.5 l/min (hence LF15). The LF05 joined the family in 2012 and is a third of the size. The LF03 is the smallest of the LF range and is a fifth of the size. Although internally they vary, the external chamber size is identical enabling interchangeability. Flows start at 0.005 l/hr (0.00008 l/min, 0.001 GPH).
| General Specifications: | |
|---|---|
| LF03 |
0-18 l/hr. |
| LF05 | 0-30 l/hr. |
| LF15 | 0-90 l/hr. |
| Accuracy | ±1% of reading, requires linearisation. Provided by all Litre Meter instrumentation. |
| Pressure Rating | Dependent on Connection size and rating. |
| Temperature rating | -40°C - +100°C dependent on material and instrument; higher temperature possible. |
| Viscosity Range | 0.5 - 100,000 cP or greater. |
| Recommended Filtration | A 100 micron filter is advisable for 100% long life serviceability. For LF03 & LF05 size 40 micron filter is recommended. |
