Analogue output
Application
The KOBOLD model DPM flow meters are used for measuring and monitoring liquids. Due to its compact construction the measuring instrument is suitable for use with machines with minimum availa- ble space. The system can be used in a wide variety of applications because the output pulses can be analysed in many different ways.
Areas of Application
● low viscosity liquids
● non-conductive liquids
● volume dosing with external electronics
● filter aid
Working principle
The medium flows through a specially shaped fluidic casing and causes a vane to rotate. This rotary motion is sensed by optoelectronics in a non-contacting manner, and converted to an asymmetric frequency signal or an analogue signal. A frequency divider with symmetrical output is available as an option. The frequency is proportional to the flow velocity.
The vane is saphire-supported: this ensures a high degree of linearity and long service life.
