It's 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 (free) stream bed elevation rods
are also included which allow velocity measurements to be made at fixed
heights above the bed of the steam.
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.
