ABB’s new series of swirl and vortex flowmeters includes the SwirlMaster, which comes in standard or extended versions and offers technology that enables very short upstream and downstream piping requirements, saving installation costs and enabling high accuracy flow measurement in tight spaces.

The extended version Swirlmaster features the ability to receive signals from other transmitters for density, temperature, and pressure via an analog 4–20 mA input. The standard model provides an analog output with HART communication. Both models feature ABB’s universal graphical display (HMI), digital outputs that are configurable as pulse, contact and frequency output, and an integrated temperature sensor that can be added as an option. The new VortexMaster also offers a lower cost version for simple applications and an extended version. Both versions are available in a remote design with a cable length of up to 30 m (100 ft).

While the measurement principle of the SwirlMaster is based on concentric swirls that create pressure fluctuations in the medium, the

VortexMaster works according to the Kármán vortex principle with turbulences generated by a bluff body. Both series have a piezo sensor with multiple elements to register the measured signals and additionally the pipe vibrations with which the measurement signal is compensated. The sensor, transmitter and general set-up for both device series is identical for easy commissioning and spare part management.

The new devices have significantly improved sensor response time, and are equipped with advanced diagnostic and verification functions. This built-in system monitors device health through regular self-checks on the flow and temperature sensor, and the data storage and electronics. The simple and robust design of the devices features no moving mechanical parts and high accuracy with +/-0.50% of rate for the SwirlMaster and +/-0.65% (liquid) or +/-0.9% of rate (gas) for the VortexMaster. Both feature an available explosion-proof design and stainless steel housing option.
