Overview

Swirl 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, 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 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.

Standard features:

HMI for easy meter set up
Analog 4 … 20 mA input
Integrated RTD for temperature compensation and saturated steam mass flow calculation
Digital outputs for pulses, frequency, and alarm signalization

Optionally available:

Remote transmitter with up to 30 m (98 ft.) cable length
Stainless steel transmitter housings
SIL 2
