Technicaldata
Type 8025 / 8035
6.3. General data
Pipe diameter
• 8025 flowmeter
• 8025 transmitter (remote versions)
• 8035 flowmeter • DN20 (except for the DN specified p.22) to DN400
• DN06 to DN400
• DN06 to DN65
Type of fitting • S020, for a compact 8025
• S030, for a 8035
Type of fluid • liquid
• viscosity: max. 300 cSt
• rate of solid particles: max. 1%
Fluid temperature (compact versions)
• with fitting in PVC
• with fitting in PP
• with fitting in PVDF, stainless steel or brass
The fluid temperature may be restricted by the fluid pressure, the
material the flow sensor is made of and the material the S020 or
S030 fitting used is made of. See "Fig. 2" and "Fig. 3".
• 0 to +50 °C
• 0 to +80 °C
• -15 to +80 °C
Fluid pressure (compact versions)
• 8025 compact
• 8035 with S030 fitting in plastic
• 8035 with S030 fitting in metal
The fluid pressure may be restricted by the fluid temperature, 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 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
