Flow Rate Sensor (FLO-BTA) is a LabQuest sensor that must be used with an interface to measure the rate of flow in a river or stream.

The dimensions of the sensor are as follows:

• Length without extension pieces: 108.5 cm
• Length with both extensions (to prevent propeller from contacting substrate): 168.5 cm
• Maximum outer diameter of tube: 2.35 cm
• Diameter of propeller: about 7 cm
• Propeller shaft: external diameter about 6.5 mm
