FLOW SENSOR FOR LIQUID MEDIA Serie 210

Transcription

1 FLOW SENSOR FOR LIQUID MEDIA Serie 0 Flow range l/min Nominal diameters DN 6 / 8 / 0 / / 0 / Temperature measurement ÀC 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 KTW, W70, WRAS

8 Influence of glycol With the following definitions we are able to correct the influence of media with higher viscosity than water (= media viscosity >.8 cst) in order to reach a measuring accuracy of % fs in the range of.8 - cst and of % in the range of - cst ( = viscosity in cst).
