A device for the visual indication of liquid flow. Flow indication is visible at a distance.
Usable with water down to a flow range of approximately 100 mL/minute, which is adequate for even the smallest cold finger condensers. The upper flow limit is in excess of 1 liter/minute. Speed of ball rotation is a semi-quantitative measure of water flow. Unit operates in any position.
- Molded of clear polycarbonate with an inert nylon indicator ball
- Light in weight
- Requires no auxiliary support
