Technical Information

Proline Prowirl 72F, 72W, 73F, 73W

Vortex Flow Measuring System

Reliable flow measurement of gas, steam and liquids

Application

For the universal measurement of the volume flow

of gases, steam and liquids.

With integrated T-measurement, the mass flow of steam,

water (as per IAPWS-IF97 ASME), natural gas (as per

AGA NX-19), compressed air and other gases and liquids

can be measured.

Maximum range of applications thanks to:

• Fluid temperature range from –200...+400 °C

• Pressure ratings up to PN250/Cl 1500

Approvals for hazardous areas:

• ATEX, FM, CSA, TIIS

Connection to all common process control systems:

• HART, PROFIBUS PA, FOUNDATION Fieldbus

Relevant safety aspects:

• Pressure Equipment Directive

•Up to SIL 2

Your benefits

The robust Prowirl sensor, tried and tested in over

100,000 applications offers:

• High resistance to:

– Vibrations (over 1 g in all axes)

– Temperature shocks (> 150 K/s)

– Contaminated media

– Water hammer

• No maintenance, no moving parts, no zero-point drift.

• Software initial settings save time and costs

In addition, Prowirl devices offer the following

possibilities:

• Complete saturated steam or liquid-mass measuring

point in one single device

• Calculation of the mass flow from the measured

variables volume flow and temperature in the

integrated flow computer

• External pressure value read-in for superheated steam

and gas applications (optional)

• External temperature value read-in for delta heat

measurement (optional)
