Flow Rate Sensor Troubleshooting and FAQs

Flow Rate Sensor, order code FLO-BTA, $129
Specifications and User Guide

TROUBLESHOOTING
Primary Test: Plug in the sensor and start up the data-collection program. Spin the impeller on the sensor and check the readings, which should be changing as the impeller spins.
-Secondary Test: (computer) Plug in the sensor, start up Logger Pro and open the Stream Flow file (Test 16, WQ w/ Computers). Submerge the impeller of the sensor in a stream to about 40% of the depth. Point the impeller upstream and directly in the flow. Collect data. When the sampling ends, a reading of flow rate should be displayed.
-Secondary Test: (calculator or Palm) Plug in the sensor and start up DataMate (DataPro on the Palm). Set up the data collection for Single Point. Submerge the impeller of the sensor in a stream to about 40% of the depth. Point the impeller upstream and directly in the flow. Collect data. When the sampling ends, a reading of flow rate should be displayed.
