SwirlMaster FSS450 is the universal but unique Swirl meter for high-end flow applications.
It uses a two-wire transmitter with leading-edge DSP technology with advanced flow computer functionality. Signals from remote sensors like pressure, temperature, or density can be computed directly with the signals from internal flow and the integrated temperature sensor.

SwirlMaster FSS450 is ideal for direct mass flow or standard flow of gases and liquids or direct mass and energy flow on saturated and overheated steam.

Overview

SwirlMaster flowmeters are used for highly accurate measurement of the flow of gases, liquids, and steam over a wide range of temperatures in almost any application. Swirl meters are ideal for use on low viscose liquids, and demineralized water, and for direct, cost-effective steam mass flow. 

SwirlMaster FSS450 is the advanced version with additional analog input for mass or energy flow measurement, available with an integral or remote transmitter with up to 30 m (98 ft.) cable length. Because of the optional inputs, discrete-flow computers are no longer needed in many applications.

SwirlMaster FSS450 is available with multiple communication protocols, such as

  • 4 to 20mA / HART 7,
  • Modbus TCP and Profinet via Ethernet -APL, 
  • Modbus RTU, Profibus PA, and FOUNDATION Fieldbus.

Optionally available:

  • Smart HMI with backlight and Bluetooth functionality for easy meter setup (Ethernet-APL device only)
  • Remote transmitter with up to 30m (98 ft.) cable length
  • Stainless steel transmitter housings
  • SIL 2
