Data Harvest

Product Description

The Flow Rate Sensor can be used for environmental or Earth science studies. Flow rate data can be used to calculate the discharge value for a stream or determine the sediment transport of a stream.


6-minute tech tip on the flow rate sensor

The Flow Rate Sensor includes 3 riser rods, which enable the impeller to be placed at fixed depths, and is equipped with a 5 m cable so your data-collection equipment can stay on shore. The Flow Rate Sensor also separates into four sections for easy transport and convenient storage

The SmartQ Vernier adaptor has been designed to provide the calibration tables and connection for compatible Vernier DIN analogue sensors to an EasySense unit.

Vernier’s DIN range of sensors has 5-pin DIN plugs for use with the ULI and Serial Box Interface. For a detailed sensor compatibility chart, please see the user manual .

Vernier produces the same range of sensors with British Telecom type connectors - BTA analogue sensors (for use with the LAB Pro, CBL & CBL2 loggers). These can also be used with the SmartQ Vernier adaptor if connected via a BTA to DIN adaptor (supplied by Vernier). Note: This does not apply to BTA sensors that do not have a DIN equivalent that is included in the compatibility list or the Vernier stainless steel Temperature probe (TMP-BTA) which is unsuitable for use with the BTA-DIN adaptor.
