VWR® Flow Indicators

Clear styrene-acrylonitrile flow indicators are temperature- and chemical-resistant, and indicators are useful for both liquid and gas flows.

• Useful for liquid and gas flows
• Styrene-acrylonitrile construction

Tapered arms connect to a variety of tubing sizes.

The ball indicator may be used vertically, for 50 mL/minute liquid flows and 3L/minute air flows, or horizontally, for 140 mL/minute liquid flows and 8L/minute air flows. The speed of ball rotation is proportional to the flow. Not for use with corrosive liquids or at temperatures above 50°C (122°F).

The free-spinning paddle wheel indicator is ideal for liquid or gas flows from 5 to 95 mL/second. Speed is proportional to flow rate. Not for use with corrosive fluids or at temperatures above 85°C (185°F).
