Vernier® Flow Rate Sensor

Easily measure stream velocity for environmental or earth science studies. Using this durable sensor, your students can measure the flow of a stream at different points, in meters or feet per second. Using flow rate data, your students will be able to calculate discharge value for the stream in m3/s or ft3/s, or determine the sediment transport of the stream. The impeller rod separates into four sections for easy transport and convenient storage. Sensor comes equipped with a five-meter cable, so your data collection equipment can stay on shore while you measure flow rate in the stream. Three riser rods are included with each sensor, which enable the impeller to be placed at fixed depths. Range: 0 to 4.0 m/s (0 to 13 ft/s).
