Flow sensor type 6 for liquid media Flow range 0.9... 0 l/min Nominal diameters DN 8 / 0 / / 0 / / Temperature measurement -0... + ÀC The type 6 is based on the type 0 but incorporates a brass housing. The Vortex Sensor type 6 has a rugged construction of brass connection. This flow sensor is available with a larger variety concerning power supply and outputs. You can choose between various versions as integrated temperature measurement. With no moving parts the flow sensor is not sensitive to debris, has marginal pressure loss and high accuracy. Flow measuring with voltage, current, pulse or frequency output Temperature non-sensitive measuring principle Excellent media resistance (measuring element not in contact with the media) Wide application temperature range Marginal loss of pressure Measuring element not sensitive to debris Direct temperature measurement in the medium Drinking water approval WRAS, ACS Huba Control type 6 - Technical data subject to change - Edition 09/08 /9
