Vortex Flow Measuring System
prowirl 70
Reliable Flow Measurement of
Gas, Steam and Liquids
Safe
• Electromagnetic compatibility accord-
ing to IEC 801 and NAMUR
• Sensor and electronics self-diagnos-
tics with alarm functions
• Proven capacitive DSC sensor:
resistant to vibration, thermal shock
and overspeeding
Flexible
• Local, manual configuration possible
with closed housing, even in hazar-
dous areas (Ex i and Ex d)
• Current output simultaneously
available with pulse, alarm or limit
output.
• Programmable current and pulse
simulation
Accurate
• Low measuring uncertainty
<1% of rate (gas/steam)
<0.75% of rate (liquids)
• Wide turndown of up to 45:1
• Every flowmeter is wet calibrated
Universal
• SMART technology permits two-way
digital communication via HART
protocol
• E+H Rackbus interface for connection
to higher level bus systems
• Meter bodies and sensors available in
a wide range of materials
• One standard, compact meter for all
fluids and the complete process
temperature range of -200...+400°C
