Type 200 - OEM Flow Sensor for Liquid Media

Sensing

Technical overview

» The flow sensor type 200 is based on the Kármán vortex trail. Vortex trail principle and is    available in various options with and 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 meadia)
» Wide Application temperature range.
» Marginal loss of pressure.
» Measuring element not sensitive to debris.
» Direct temperature measurement in the medium with PT1000 or NTC.
» Dringking water approval KTW, W270, WRAS.
