Mechanical flowmeters are ideal for general purpose flow measurements in a range of aquatic habitats. Incorporating a precision moulded rotor connected to a six-digit counter, each revolution of the impeller is registered on the mechanical display. The number of revolutions per unit of time can be translated into stream flow velocity using a conversion chart included in the manual.
Available with either a standard or low-speed rotor. Models are also available with a 1-way clutch so that the rotor can only work in one direction. This is useful in situations where the user wants to prevent the reading from being reversed by possible reverse flow.
The flow meter can be attached to our 250mm, 300mm frame or 500mm frame plankton nets.
