Stream Flowmeter - Basic model

Measure the rate of flow of a stream with the original easy-to-use Geopacks flowmeter.

It's fitted with a re-settable LCD counter and powered by long-life batteries (included).

If you are still measuring stream flow with an orange (and multiplying by 0.6) a GEOPACKS FlowMeter could be just the piece of equipment for you. Ideal for school and college field trips, student projects, practical river irrigation studies and water resource management. Your GEOPACKS FlowMeter comes with a 30-page book containing technical specifications, instructions for use, care and maintenance, conversion and calibration charts and useful guidance on carrying out interesting field work projects.

How does a GEOPACKS FlowMeter operate? Revolutions of an impeller are sensed electronically and transmitted to a hand-held counter unit. The number of revolutions per unit of time can be translated into stream flow velocity using a conversion chart. Our impeller sticks have been accurately calibrated in a flume tank.

We rate the sticks at 0.5MPS to 1.5MPS, this is a safe operating range for Children. Accuracy is + or - 5%.

Contains only the basic flowmeter

We now have an Advanced Flowmeter with auto logging and no need for conversion charts.
