PASPORT Flow Rate/Temperature Sensor - PS-2130



Our Flow Rate Sensor allows students to measure the rate of movement and temperature of streams, rivers and other flowing systems. The impeller is a rugged, single-piece unit encased by protective material — no more losing pieces to the bottom of the stream.

  • Revolutions of a magnet on the submersible impeller are counted and converted to linear flow rate measurements in ft/sec or m/s.
  • Students can use DataStudio software to calculate volume discharge rates.
  • Exclusive built-in temperature sensor conveniently measures temperature at the same point as flow rate.

Typical 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
