DFS1 series turbine flow sensors are designed to accurately measure small quantities of liquid, whereby both the instantaneous flow rate can be recorded and the quantity that has flowed through can be counted.
The liquid flowing through the DFS 1 causes the impeller to rotate. The speed of the impeller is proportional to the volume flow rate over a wide range. Via a contactless magnetic pick-up, the speed of the impeller is available as a pulse frequency proportional to the flow rate for digital evaluation, optionally as voltage (0-10 V) or current (4-20 mA).
The large number of pulses results in a good resolution. The response time is very short due to the low mass of the impeller. A stabilising section in the pipework upstream/downstream of the sensor is not necessary.
The simple mechanical design of the DFS 1 turbine flow meter means that a long service life can be expected without any loss of accuracy. Pressure surges cannot damage the measuring system.
