Installation Requirements
• A Vortex or Swirl flowmeter can be installed at any point in the pipeline system. However, the
following installation conditions must be considered:
• Compliant ambient conditions (see data sheet D184S035UXX)
• Compliance with the recommended inflow/outflow sections
• The flow direction must correspond to that indicated by the arrow on the flowmeter sensor.
• Compliance with the required minimum interval for removing the transmitter and replacing
the sensor (see data sheet D184S035UXX)
• Avoidance of mechanical vibrations of the pipeline (by fitting supports if necessary)
• The internal diameter of the flowmeter sensor and the pipe must be identical.
• Avoidance of pressure vibrations at zero flow by fitting gates at intervals in long pipeline
systems
• Attenuation of alternating (pulsating) flow during piston pump or compressor conveying by
using appropriate damping devices. The residual pulse must not exceed 10 %. The
frequency of the conveying equipment must not be within the range of the measuring
frequency of the flowmeter.
• Valves / gates should normally be arranged in the flow direction downstream of the
flowmeter (typically: 3 x DN). If the medium is conveyed through piston/plunger pumps or
compressors (pressures for fluids > 10 bar (145 psi)), it may be subject to hydraulic vibration
in the pipeline when the valve is closed. If this does occur, the valve absolutely has to be
installed in the flow direction upstream of the flowmeter. Suitable damping devices (e. g. air
vessels) might need to be fitted.
• When fluids are measured, the sensor must always be filled with media and must not run
dry.
• When fluids are measured and during damping there must be no evidence of cavitation.
• The relationship between the temperature of the media and the ambient temperature has to
be taken into account (see "Ambient conditions" in the section titled "Technical data").
• At high media temperatures > 150 °C (302 °F) the flowmeter sensor must be installed so that
the electronics are pointing to the side or downward.
