Safety instructions
1.1 Intended use
The vortex flowmeters are made to measure the flow of gases, steam and liquids.
The devices are particularly suitable for the measurement of:
• Clean liquids with low viscosity (< 10 cP)
• Hydrocarbons with low viscosity (< 10 cP)
• Water
• Chemicals with low corrosiveness
• Saturated steam
• Superheated steam, including CIP and SIP applications in the food industry
• Industrial gases
The devices are rated for the following flow velocities:
• Liquids: 0,3...7 m/s / 1.0...23 ft/s
• Gases and steam: 2.0...80 m/s / 6.6...262 ft/s
DN15: 3.0...45 m/s / 9.8...148 ft/s; DN25: 2.0...70 m/s / 6.6...230 ft/s
If there is a risk of waterhammers in steam networks, appropriate condensate separators must
be installed.
Suitable measures must be taken to avoid water cavitation if it is a possible risk.
• The sensors are made from Stainless Steel 316 L (1.4404) or Hastelloy
®
C22.
• In your project planning, please observe the data given in the corrosion tables.
• The pressure-bearing parts have been designed and rated for stationary operation taking into
account the maximum pressure and temperature.
• External forces and moments, caused e.g. by pipe stresses, have not been taken into account.
Primarily, volumetric flow and temperature are measured, with pressure measurement as an
option. From these parameters the measuring device calculates the mass flow or standard
volumetric flow using pre-programmed density data and then exports the measured values via
various communication interfaces.
CAUTION!
The operator himself bears the sole responsibility for the intended use of the device regarding
the suitability and the corrosion resistance of the used materials against the measured fluid.
