http://U324_ZS25UFA_DoP_e_100414 www.hoentzsch.com 1/6 Vane wheel flow sensor ZS25 with optional integrated transducer UFA Vane wheel flow sensor ZS25 (see Page 3 for dimensions) Functional principle • vane wheel flow sensor • scanning the vane rotation; non-contact inductive proximity switch Advantages • low starting value • large measuring range span • maximum fatigue strength thanks to vane wheel which is easy on the bearings • corrosion resistant • sterilisable • high working temperature and pressure ranges • operates to a large extent irrespective of density and composition of the gas • low pressure drop • easy adjustment to process parameter Medium • air, gas mixtures and clean gases Humidity in the gas • relative gas humidity of less than 100 % does not affect the measurement uncertainty Range and examples of application • flow rate measuring, e.g. of air, exhaust gas, process gas • monitoring laminar flow • monitoring flow in pharmaceutic works Measuring range • 0.4 ... 120 m/s Measurable variable • standard flow velocity v [m/s] in air/gases Drawing 4 Design • insertion probe with AS80 housing Flow measurement with sensors ZS25 at working temperatures up to +500 °C optional with integrated and configurable transducer UFA
