The main feature of the DF fl ow sensors is the
incorporation of a multipole magnet ring embedded
into the paddlewheel. As the paddle wheel rotates,
the magnets, hermetically separated from the liquid
media, induce a DC signal into a Hall-Effect sensor
mounted on the device housing. Since the DC signal
frequency is proportional to paddlewheel rotation, an
accurate fl ow rate reading is possible.
The DF sensors, when coupled with the appropriate
KOBOLD electronics unit, can offer the user a number
of features useful in the measurement and control
of low viscosity liquid fl ow. These features include a
frequency output, analog output, adjustable switches,
digital displays with integrated batch controllers, or
totalizers.
The KOBOLD DF Flow Sensor is used in applications
where fl ow measurement is desired and fl ow rate
data is to be transmitted as a pulse rate output. The
DF Flow Sensor contains a fl ow transducer which
transmits a pulse signal. The output signal is linearly
proportional to the fl ow and is transmitted by a bipolar
transistor operating in an open collector confi guration
(10 mA sinking capability).
