The new SITRANS F is a cost-effective meter for measuring liquid flows. It involves a
totally new patent which is unique to Siemens. A key point is that the flow meter is
profile-independent, thereby guaranteeing a highly accurate reading. A further benefit of
the SITRANS F ultrasonic flow meter is that it can directly replace conventional flow
meters (e.g. electromagnetic, vortex etc.)
The SITRANS F ultrasonic flow meter will compete directly with vortex-type flow meters,
which normally offer turn-down ratios of around 10:1 maximum. SITRANS F provides much
greater versatility, enabling it to be used for the widest possible range of flow
applications. Accuracy is dependent on turn-down and stands at 1% at 100:1 turn-down and
0.5% at 25:1 turn-down. The unit offers 4-20mA, with HART output as standard, and features
local parameterization via an optical touch screen.
SITRANS F Ultrasonic flowmeters
SITRANS F is characterized by the following features:
Flow measurements with laminar and turbulent flows and also in the
transition region
High measuring accuracy over a very wide flow range as a result of the
helical scanning of the flow profile
Nominal diameters from DN 25 to DN 100
Compact design
Metering tube and flange made of stainless steel
Separate junction box
High long-term stability resulting from digital signal processing
EMC-tested to EN 50 081, EN 50 082 and NAMUR
Self-monitoring/diagnosis
Analog output and two digital outputs for pulses, device status, limits,
flow direction
Outputs electrically isolated from the power supply and from one another
HART communication
Simple menu-based operation with two-line display and four optical input
elements
Measurement of wall thickness of metering tube on request.
