AVi Miniature Turbine Meters

Product code: AVi

Product Overview

This high performance low-flow miniature turbine meter provides instantaneous response even at extremely low flows. Featuring photo-electric sensing, the AVi is constructed from chemically inert materials making it suitable for many liquid and trace chemicals. The rotor is near weightless in liquid meaning there is negligible bearing wear. Available in frequency output, the meter offers instantaneous, batch and totalised flow measurement. The rotational speed of the miniature axial flow rotor is sensed by a photo-electric eye, allowing fast and accurate measurement over a very wide range of flows. A voltage output option is also available.
