The Valeport Braystoke Model 001 and Model 002 flow meters provide a cost effective and reliable method of monitoring flow in a variety of environments, including salt, fresh and effluent water, from shallow streams to tidal waterways. The meters benefit from the design of the impeller bearings, which give low threshold velocity and consistent performance. Their ease of operation make the 001 and 002 ideal for field study use and an invaluable tool for hydrometric work. Available as either a wading or suspension set, all systems are supplied with the Model 0012B real time control display unit.
