Strongly supports energy-saving activitiesStrongly supports energy-saving activities
Integrating flow and instantaneous flow rate displays can be
switched with a single operation .
Correction of pressure/temperature is not required.
· No need for pressure correction = Due to the mass detection
method used, there is no effect due to pressure change.
Hence, pressure correction is not required.
Displays the flow rate converted to atmospheric pressure (1 atm).
· No need for temperature correction = Fluid temperature
is detected by the platinum thin film temperature sensor,
and is always displayed after being converted to flow
rate at 0°C.
·Maintenance and measurement of air quality
available in one unit.

● Secure design that is hard to break even with drain (water drops)
(double the environment-resistance compared to conventional products)
·Improved water resistance by applying
a special coating to the platinum thin-film sensor.
·Overheating of the sensor element is prevented
by a protection circuit.

High precision of practical precision ±3% F.S.
Pressure loss 0.005 MPa (primary pressure: 0.7 MPa)
is realized
*1
By laminating the rectification filter,
pressure loss is reduced to 0.005 MPa.
(*1: Applicable models only)
Straight piping section not required
*2
Thanks to the rectifier, there is no impact even if the elbow and
T-shaped socket are piped just before the sensor.
(*2: Excluding PF8000/PF16000F)
With no need for correction, practical precision ±3% F.S. is realized at
temperature 0 to 40°C and pressure 0.1 to 1.0 MPa.
■ Pipes can be installed in any orientation, vertical,
horizontal, etc.
· The display unit can be rotated up to 270° as desired.
·Connector wires can be drawn out along the piping
and do not occupy space.
·Connector wires can be drawn from either IN or OUT
side by rotating the connector case 180°.
