CKD FLUEREX PF Series - Applications of Flow Sensor; Flow rate management examples; Functional explanation

Applications
The sensor of FLUEREX consists of a rectier that converts the
compressed air to a uniform ow and a platinum thin lm resistor that
detects the ow rate. The rectier works to make the ow uniform
when a bent pipe such as an elbow is installed immediately before the
sensor. Through the use of multiple rectication plates, the pressure
loss is suppressed and an adequate rectication effect is realized.
When the compressed air does not ow, the platinum thin lm
sensor that detects the ow rate is heated from the uid temperature
to a certain constant temperature. When the compressed air ows,
the amount of heat proportional to the weight of air is detracted and
the current that intends to maintain the constant temperature ows
in the circuit inside the platinum thin lm sensor that detects the ow
rate. By receiving this current as a ow rate signal, the display
section displays a practical atmospheric pressure, instantaneous
ow rate or integrating ow of the air converted to 0°C.
In addition, by the platinum thin film sensor that detects the
fluid temperature, the temperature of the compressed air is
measured and the temperature correction is performed.
