Sparling Propeller Flow Meters have a blade which rotates as the flow passes. These rotations are interpreted as flow by a totalizer usually mounted on the meter. Propeller meters do not require a power source to totalize flow. When equipped, the propeller meter can send an output signal (requiring an external power supply) to a remote location. The propeller meter is a low cost, low maintenance meter.
Fields of Application
- Clean water flows – Props can measure liquids with up to 5% suspended solids at temperatures up to 100°F
- Uncertain or unavailable power – Does not require power to operate
- Wide size range – Available in sizes up to 72″
- Accuracy – Fairly good at ±2% standard
