PASPORT Flow Rate/Temperature Sensor

The PS-2130 Flow Rate/Temperature Sensor measures the flow rate and temperature of moving water. The impeller
housing contains a propeller mounted on a low friction brass shaft. Magnets on the propeller revolve as the propeller
turns, and the revolutions are recorded by a Hall effect sensing element.

Flow Rate Sensor PS-2130 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
