5 OPTISWIRL 4070 C SAFETY Intended use The vortex flowmeters are made to measure the flow of gases, vapors and liquids. These flowmeters are particularly suitable for measuring: 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 meters are rated for the following flow velocities: From 0.3 to 9.0 m/s for liquids From 3.0 to 80 m/s for gases and vapors 1 1 DN15-3,0 to 45 m/s DN25-3,0 to 70 m/s If the danger of waterhammers can occur in steam net works appropriate condendsate separators have to be installed. If the danger of water cavitations can occur appropriate measures have to meet. WARNING! The operator himself bears the sole responsibillty for the intended use of the flow meter regarding the suitability and the comision resistance of the used materials against the measured fluid. The manufacturer sis not liable for any damage resulting from improper use or use for other than the intended purpose. Do not use any abrasive or highly viscous media < 10 cp. INFORMATION! The sensors are fabricated from stainless steel 316 L (1.4404) or Hastelloy C4. 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 account of maximum pressure and temperature. External forces and moments, caused e.g. by pipe stresses, have not been considered thereby. Primarily, volumetric flow and temperature are measured, with pressure measurement as an option. From these parameters the flowmeter calculates the mass flow or standard volumetric flow using pre-programmed density data and then issues the measured values via various communication interfaces. 12/

49 OPTISWIRL 4070 C TECHNICAL DATA Functional principle Vortex flowmeters are used to measure the volumetric flow of gases, vapors and liquids at completly filled pipes. The measuring principle is based on the Karman vortex street. The measuring tube contains a bluff body, behind which vortex shedding occurs. The frequency f of the vortex shedding is proportional to the flow rate v. The nondimensional Strouhal number S describes the relationship between vortex frequency f, width b of bluff body and and the mean flow velocity v: f = S. v b The vortex frequency is recorded at the sensor and evaluated at the converter. v b b b Figure 8-1: Functional principle 12/
