KROHNE OPTISWIRL 4200 vortex flowmeter for steam, gas and liquids, integrated P and T

The KROHNE OPTISWIRL 4200 is a vortex flowmeter for general plant applications and energy management. One housing contains flow, pressure and temperature sensors and a flow computer, providing mass, normalized flow, energy and gross and net heat of steam and hot water. The manufacturer estimates installation savings of about 45% compared with external P and T sensors and a separate flow computer.

It measures liquids, wet gases, saturated and superheated steam up to +240 °C. Flanges DN15…300, wafer up to DN100, 2-wire 4…20 mA, HART, FF, Profibus-PA. SIL 2/3, dual version for redundancy, AVFD signal filtering and a shut-off valve to replace the pressure sensor without process shutdown.
