Overview
Swirl flow meters can be utilized 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 petrochemical raw materials, demineralized water and for direct, cost- effective steam mass flow by employing integral temperature measurement.

SwirlMaster FSS430 is the standard design with excellent vibration cancellation and analog output with HART communication. Optionally available with HMI and digital outputs. Available with integral or remote transmitter with up to 30 m (98 ft.) cable length.
