Vortex flow sensor OEM Flow sensor for liquid media Type 200 The flow sensor Type 200 is based on the Karman Vortex principle. You can choose between various versions. The Type 200 is available with or without temperature measurement. With no moving parts the flow sensor is not sensitive to debris, has marginal pressure loss and high accuracy. + Low cost product with high levels of accuracy + 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 with PT1000 or NTC + Drinking water approval KTW, W270, ACS, WRAS Huba Control Type 200 | Technical data subject to change | Edition 09/2020
