2.1 Device description
Vortex flowmeters measure and display the flow of flammable and non-flammable gases, steam
and liquids. They transmit a 4...20 mA or digital multidrop, and a pulse output signal, as
applicable, using HART
®
communication protocol for remote configuration, calibration and
monitoring.
2.2 Marking
The marking of the devices is shown on the nameplate below. On both the compact devices and
the remote versions, the main plate is located on the signal converter housing. When the
flowmeter is remotely mounted, the junction box on the flow sensor body has a nameplate
showing its hazardous location rating.
Compact devices with two signal converters for dual measurement (Dual Version) are each
marked with a nameplate. The details relevant to explosion protection are identical on both
nameplates.
