Stream Flowmeters
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.

Service Repairs and Upgrades
GEOPACKS FlowMeters are supplied with a full 12-month guarantee and if products do not immediately meet with your expectations, your purchases will be refunded.

Geopacks FlowMeters in action
Take a look at our FlowMeter in action in the Extreme Arctic. The British Schools Exploring Society Expedition led a team of 15 young people and 7 leaders to explore the archipelago of Svalbard to study the onset of the formation of rivers during the melting season, and the phenomenon that are "slush surges". The research unit spent 22 days in Tobredalen valley studying environmental changes, click here to see the team using Geopacks FlowMeter.

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

GEOPACKS Advanced FlowMeter
The new GEOPACKS Advanced Stream FlowMeter connects to the same sturdy impeller stick as the standard MFP51 meter but boasts a much more sophisticated meter which does away with the need for conversion charts. The new meter displays velocity in units of metres per second or mph and has an inbuilt logger function that allows you to choose between manual logging and auto logging. Auto logging allows you to take a reading at programmed intervals, say every 5 minutes, and record the result. All readings are then stored in a CSV file that can easily be downloaded to your PC via the mini USB cable provided. Powered by a standard AA battery (included), the Flowmeter also comes with a carrying pouch for added protection, a collapsible impeller stick and a compact case for transporting and storing the whole kit
