SDF Flow Sensors
SDF flow sensors are highly accurate
instruments which are used for measuring flow rates of gases,
steam and liquids. SDF sensors are approved in inumerbale
applications. They are suitable for highly sophisticated
requirements.
Application areas:
- Process measurements
of nromal air, pressurized air, natural, combustion and
other gases, even with extremely high temperatures (up
to 1200°C)
- Steam measurements for pressures up
to 180 bar and temperatures up to 560°C
(->more)
- Flue gas flow measurement
(even according to 17. BImSchG), especially for steam
saturated gases, high dust loads, corrosive atmospheres
etc.
(->more)
- Flow measurements in liquids
with medium or low viscosity
- Continuous measurements where no process
interruption for assembly/disassembly is possible (->more)
Essential features:
- Easy to install
- Low remaining pressure drop
- No moving parts
- High long term stability
- Nearly maintenance free
- Safe prevention of capillar action
- High stability against mechanical stress
combined with low self-weight
- Measurement in both directions is possible
- Wide linearity range
- Wide scope of materials and therefore
highest resistiveness against corrosion
- Error margin (apporved accuracy)): ±1%
from the measured value - independent from wearout at
the outside shape of the sensor
- Repeatability: ±0,1%
- Standard material: 316SS - optional
materials are Hastelloy B and C in different variations,
Monel, 1.4539, Inconel, alloy 625 u.v.a.m.
- Application ranges: pressure between
0..640 bar and temperature between -200..+1200°C
