DFS5.1 Doppler Type Flow Switch

DFS5.1 Doppler Type Flow Switch Contact output model. Easy installation because it equips only one sensor. Suitable for turbid liquid such as waste water, slurry, sludge etc. Check the flow velocity change with LED bar graph on the controller. Applicable pipe diameter φ12.5mm～φ4500mm. ,1,100,1,dfs5-1-doppler-type-flow-switch,,2020-06-25 01:24:00,,9113,0,,0,, DFS5.1 Doppler Type Flow Switch, [5090] Ultrasonic Liquid Flow Meter PF/U/TTFM/PTFM/DFM/DFS Series, Operating Principles Transit Time Type Ultrasonic waves are transmitted into a liquid alternately from the 2 sensors attached to the outside of the pipe, and difference between the propagation time of the ultrasonic wave in the upstream direction and the propagation time in the downstream direction is detected to obtain the flow velocity. Then, the flow rate is calculated by multiplying the cross section area of the pipe diameter. Doppler Type The sensor transmits ultrasonic into the liquid through the pipe wall. Ultrasonic reflects the granules or air bubbles in the liquid. When the liquid flows, echos come back to the sensor with a different frequency besed on the flow velocity. We can calculate the flow velocity based on the frequency change. , Model PF330A/330B/330D PF220A/220B Power Source 110～240VAC ±10% 110～240VAC ±10% Battery Battery Life-20 hours from fully charged, depending on load.
