73F Vortex flowmeter

Universal volumetric flow measurement of gases, steam and liquids. Thanks to the built-in temperature measurement and the reading of an external pressure value (Prowirl 73), the mass flow of steam, water (in accordance with the IAPWS-IF97 ASME standard), natural gas (in accordance with the AGA NX-19 / AGA8-DC92 detailed method / AGA8 Gross Method 1 / SGERG-88 standard), compressed air, other gases and liquids can be calculated.

Benefits

• The Prowirl sensor family has passed more than 200,000 tests and verifications and offers the following advantages:

• High vibration resistance, resistance to temperature shocks, suitable for contaminated fluids, resistance to water hammer

• Maintenance-free, no moving parts, no zero-point drift (“lifetime” calibration)

• Software-based initial setup saves time and operating costs

• Extended applications:

• A single instrument measures the mass flow of saturated steam or liquids

• Built-in flow computer calculates the mass flow based on the measured volumetric flow and temperature values

• External pressure input for measuring superheated steam and gases

• External temperature input for heat exchange measurement

Application

• Fluid temperature range: –200 ... +400 °C (–328 ... +752 °F)

• Pressure ratings up to PN 250 / Class 1500 

• The sensor features an integrated reducer, with selectable one-stage reduction (type R) or two-stage reduction (type S)

• Optional dual-sensor flowmeter (Dualsens type) for redundant measurement, with two sensors and two sets of electronics

• Hazardous area approvals:

• ATEX, FM, CSA, TIIS, NEPSI, IEC

• HART, PROFIBUS PA, FOUNDATION Fieldbus (FF)

• Pressure Equipment Directive (PED), SIL-2 safety
