Product Summary
PASCO’s Flow Rate Sensor allows students to measure the temperature and rate of movement of streams, rivers, and other flowing systems. The propeller is a rugged, single-piece unit encased by protective material — no more losing pieces at the bottom of the stream.
Features
- Telescoping Handle to reach deep levels.
- Revolutions of a magnet on the submersible impeller are counted and converted to linear flow rate measurements in ft/s or m/s.
- Students can use Capstone or SPARKvue software to calculate volume discharge rates.
- Exclusive built-in temperature sensor conveniently measures temperature at the same point as flow rate.
Applications
- Determine sediment transport rate for a stream or other body of water
- Measure and compare flow rate at various locations in a stream
- Compare the characteristics of one stream to another
