6.1.3 Fluid data of a 8025 Batch in compact version
Type of fluid
neutral or slightly aggressive liquids
Fluid viscosity
max. 300 cSt
Rate of solid particles
max. 1%
Fluid temperature
The fluid temperature may be restricted by the fluid pressure
and the material the S020 fitting used is made of (see Fig. 8)
• with S020 fitting in PVC • 0...+50°C
• with S020 fitting in PP • 0...+80°C
• with S020 fitting in PVDF, stainless steel or brass • –15...+80°C
Fluid pressure
PN10 max
The fluid pressure may be restricted by the fluid
temperature and the material the S020 fitting used is made
(see Fig. 8)
Flow rate measurement
• Measurement range • 0,3...10 m/s
• Measurement deviation
- with standard K-factor of the S020 fitting
- ±2.5% of the measured value
1)
- with K-factor determined with a Teach-In
procedure
- ±1% of the measured value
1)
(at the value of the
Teach-In flow rate)
• Linearity • ±0,5% of the full scale (10 m/s)
• Repeatability • ±0,4% of the measured value
1)
1)
Determined in the following reference conditions: medium = water, water and ambient temperatures 20 °C, min. upstream
and downstream distances respected, appropriate pipe dimensions
