The SwirlMaster flow meter comes standard (FSS430) or as an extended version (FSS450). The company’s swirl technology enables very short upstream and downstream piping requirements that save installation costs and enable high accuracy flow measurement in tight spaces. The FSS450 features functions normally found in flow computers, such as steam-power calculation — with and without condensation return — and the ability to receive signals from other transmitters for density, temperature and pressure via an analog 4–20-mA input. The FSS430 omits the flow computer algorithms but provides an analog output with HART communication. Both models feature digital outputs — configurable as pulse, contact and frequency output — and an optional integrated temperature sensor.
