Geopacks Flowmeter Standaard

Measure the rate of flow of a stream with this easy-to-use flowmeter produced by Geopacks. The Flowmeter Standard is fitted with a re-settable LCD counter and powered by long-life batteries (included). The flow meter also comes with a protective carrying pouch, a sturdy impeller stick and a compact, weather-proof carrying case for the whole kit. Three stream bed elevation rods are also included which allow velocity measurements to be made at fixed heights above the bed of the stream.

We also have the Flowmeter Advanced in stock which contains auto logging and there is no need for any conversion charts. If you are still measuring stream flow with an orange (and multiplying by 0.6) a 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 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 standard 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. The impeller sticks have been accurately calibrated in a flume tank.
