Technical data
Type 8025/8035 /
Fluid pressure (compact ver-
sions)
• 8025 compact
• 8035 with S030 fitting in
plastic
• 8035 with S030 fitting in metal
The fluid pressure may be
restricted by the fluid tem-
perature, the material the flow
sensor is made of (only for the
compact 8025) and the material
the fitting used is made of. See
"Fig. 2" and "Fig. 3".
• PN10
• PN10
• PN16 (PN40 on request)
Flow rate measurement
• Measurement range
- Sensor with pulse output
(Hall)
- Sensor with a sinus output
(coil)
• Accuracy
- with a teach-in procedure
- with the K factor of the
fitting used
• Linearity 1)
• Repeatability 1)
- 0.3 m/s to 10 m/s
- 0.5 m/s to 10 m/s
- 1 % of the measured value
(at the value of the teach-in
flow rate)
- 2,5 % of the measured
value
• ±0,5 % of the full scale
• ±0,4 % of the measured value
1) Determined in the following reference conditions: medium = water, water
and ambient temperatures 20 °C, min. upstream and downstream distances
respected, appropriate pipe dimensions
