2 Operating Principle Vortex Flowmeter The operation of the Vortex Flowmeter is based on the Karman Vortex Street principle. As a fluid flows past a shedder body, vortices are alternately formed on both sides. These vortices are shed due to the flow stream forming a vortex street (Karman Vortex Street) as shown in (Fig. ). The vortex shedding frequency to be measured is therefore only a function of the flow velocity and is independent of the fluid density and viscosity. The local pressure changes associated with the vortex shedding are detected by a Piezo-Sensor and converted into electrical pulses representing the vortex shedding frequency. This flowrate proportional frequency signal coming from the flowmeter primary is processed in the converter. Swirl Flowmeter The inlet guide body forces the entering fluid to rotate. In the center of this rotation a vortex core is formed which is forced into a secondary spiral shaped rotation by the backflow (Fig. 3). Piezo Sensor Outlet guide body Inlet guide body Shedder Piezo-Sensor Fig. : Principle of Operation FV000 The frequency f of the vortex shedding is proportional to the flow velocity v and inversely proportional to the width of the shedder d: v f = St -- d St, the Strouhal Number is a dimensionless number which defines the quality of the vortex flowrate measurements. When the shedder is dimensioned appropriately, the Strouhal No. St is constant over a wide Reynolds No. range (Fig. ). v D Re = ϑ = kinematic viscosity ϑ D = meter pipe diameter Fig. 3: Housing Principle of Operation FS000 Stagnation point The frequency of this secondary rotation is proportional to the flowrate and for an optimally designed internal geometry is linear over a wide flow range. This frequency is measured by a Piezo Sensor. The flowrate proportional frequency signal coming from the flowmeter primary is processed in the converter.

4 Specifications Vortex Flowmeter FV000-VT/VR Flowmeter Size Selection The flowmeter size is determined from the maximum operating flowrate Q V max. To achieve the maximum flow range, this value should not be less than one half of the maximum flowrate for the meter size (RangeMax), but can be selected as low as 0.5 RangeMax. The start of the linear flow range is a function of the Reynolds Number (see Accuracy Specifications). If the flowrate to be measured is specified as normal flowrate, (normal conditions: 0 C, 03 mbar) or as mass flowrate, the values must first be converted to actual flowrate values at operating conditions and then the appropriate meter size can be selected from the Flow Range Tables (Tbls.,, 3).. Convert normal density ( ρn ) --> operating density ( ρ ),03 + p 73 ρ = ρ n , T. Convert to flowrate at operating conditions (Q V ) a) starting with normal flowrate (Q n ) --> ρn, T Q V = Q n = Q ρ n ,03 + p 73 b) starting with Mass flowrate (Q m ) --> Q Q V = m ρ 3.

A inlet straight section length 5 times the nominal diameter should be provided. After elbows the straight length should be at least 5 times, for double elbows at least 50 times the nominal diameter. At the outlet, a straight length of 5 times the nominal diameter should be maintained (Fig. 0). ) For the supply power circuit terminals 3, 3 and contact output, cables, suitable for temperatures to T = 0 C, can be used without restrictions. Cable only suitable to T = 80 C, reduce the temperature ranges as shown in Fig. 9. These reductions also apply to the VR (Remote Design) version and the PROFIBUS PA design with plug connectors. Fig. 9: Relationship. Fluid Temperature/Ambient Temperature Information! For temperatures < 0 C and > 55 C the readability of the display may be compromised. The functionality and the outputs of the instrument are unaffected. Ambient temperatures < -0 C see Ordering Information. Converter specifications begin on Page 8 Fig. 0: Regulating and control devices should be installed at least 5 x D downstream (Fig. ). Fig. : Installation of Control Devices If the system utilizes a piston pump or compressor to produce the flow, (pressures for liquids > 0 bar) water hammer may occur when the valve is closed. In this case it is essential that the valves be installed upstream of the flowmeter. Otherwise a suitable dampening device (e.g. a tank when using a compressor) should be provided. 0

11 Supplementary Installation Information For liquids assure that the flowmeter primary is always completely filled with fluid. In horizontal installations with fluid temperatures > 50 C see Fig. for installation requirements. If gas bubbles may be present, a gas separator should be provided. For installation in long pipelines susceptible to vibrations, they should be damped up- and downstream of the instrument. Centering the Wafer Design Flowmeters The wafer design flowmeter is centered using the outside diameter of the flowmeter primary body and by its mounting bolts. In addition, as a function of the pressure rating, centering sleeves for the bolts, a centering ring (to DN 80 [3 ] or segments may be ordered as accessories (see Fig. ). Centering Ring Bolts Centering Segments Fig. : Installation for High Fluid Temperatures Fig. : Centering the Wafer Design using Centering Rings or Segments Pressure and temperature measurements should be made downstream from the flowmeter (Fig. 3).

18 Specifications Swirl Flowmeters FS000-ST/SR (TRIO-WIRL S) Meter Size Selection The flowmeter size is determined from the maximum operating flowrate Qvmax. To achieve the maximum flow range, this value should not be less than one half of the maximum flowrate for the meter size (RangeMax), but can be selected as low as approx. 0.5 RangeMax. The start of the linear flow range is a function of the Reynolds Number (see Accuracy Specifications Page ). If the flowrate to be measured is specified as normal flowrate, (normal conditions: 0 C, 03 mbar) or as mass flowrate, the values must first be converted to actual flowrate values at operating conditions and then the appropriate meter size selected from the Flow Range Tables (Tbls. 5, 6, 7).. Convert normal density ( ρn ) --> operating density ( ρ ),03 + p 73 ρ = ρ n , T.

24 Installation Swirl Flowmeter FS000-ST/SR (TRIO-WIRL S) The flowmeter primary should be installed in the pipeline taking Supplementary Installation Information into consideration the following information. In- and Outlet Sections Based on the operating principles the Swirl Flowmeter, it essentially does not require any in- or outlet straight sections. Fig. 3 shows the in- and outlet sections for various piping conditions. No additional in- or outlet sections are required when single or double elbows with a radius larger than.8 x D are installed upor downstream from the instrument. Likewise, no additional in- or outlet sections are required downstream from flanged reducers per DIN 855 (a/ = 8 ). For liquids assure that the flowmeter primary is always completely filled with fluid. In horizontal installations with fluid temperatures > 50 C see Fig. for installation requirements. If gas bubbles may be present a gas separator should be provided. For installation in long pipelines susceptible to vibrations, these should be damped up- and downstream of the instrument. 3D D 3D D min.8 D Fig. : Installation for High Fluid Temperatures 3D D Pressure and Temperature Measurements 5D D P T 3D 3D 3 x D 3-5 D -3 D Fig. 3: In- and Outlet Sections Fig. 5: Installation with Pressure and Temperature Measurements Information for Installation of Regulating and Control Devices If the system utilizes a piston pump or compressor to produce the flow, (pressures for liquids > 0 bar) water hammer may occur when the valve is closed. In this case it is essential that the valves be installed upstream of the flowmeter. Otherwise a suitable dampening device (e.g. compression tank when using a compressor) should be provided. Pressure and temperature measurements should be installed as shown in Fig. 5:. To use the internal temperature measurement see information in the Chapter Converter.
