About this product

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. 

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.

The flow meter can be attached to our 300mm frame or 500mm frame plankton nets. Please contact Customer Services (customer.services@nhbs.com or +44 (0)1803 865913) for more information or custom requests.
