Flow sensor type 210 for liquid media

Transcription

1 Flow sensor type 0 for liquid media Flow range l/min Nominal diameters DN 6 / 8 / 0 / / 0 / Temperature measurement ÀC The flow sensor type 0 is based on the ármán vortex trail principle. In comparison to the OEM flow sensor (type 00), the type 0 is available with an increased range of power supply and output signals all with and without 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 or frequency output Temperature non-sensitive measuring principle Excellent media resistance (measuring element not in contact with the media) CE conformity Wide application temperature range Marginal loss of pressure Measuring element not sensitive to debris Direct temperature measurement in the medium Drinking water approval TW, W70, WRAS, ACS Huba Control type 0 - Technical data subject to change - Edition 08/06 /9
