2.1. Valmet TS-FT
The Valmet TS (Fig. 1) consists of the sensor unit and
TCU operating unit. The sensor is available in 7 sizes,
FT50–FT300, with pressure rating PN16.
With pressure rating PN100 the sensor is available
in three sizes in the range FT100 - FT200. The appro-
priate model is selected according to the required
pressure rating and the diameter of the process pipe.
Valmet TS is compliant with ATEX II 3G Ex nR IIA
T6 Gc.
The body of the flow-through sensor consists of a
pipe section that forms part of the process pipeline
once installed. Flush-mounted antennas are installed
on opposite sides of the sensor body, and measure-
ment takes place through the pipe. The sensor electron-
ics housing is installed to the sensor body by means
of a connecting pipe.
A temperature sensor (Pt-100) is installed inside the
connecting pipe. Antenna cables, installed in a protect-
ive tube, run along the outside of the connecting pipe
and connect to the electronics housing.
All wetted sensor and antenna parts are made of
AISI 316/316L. The antenna material is polished
ceramic.
