Warnings & safety information
Always check input voltage & frequency before making any connections.
Incorrect connections will damage the equipment! Always follow the ap-
plicable electric safety regulations in all installation work!
Before any welding works in the vicinity of the devices, make sure that
operating voltage is not connected!
During installation, maintenance and service operations, remember that
the sample line may contain hot sample or water – be careful!
This equipment (sensor unit) is suitable for use in ATEX ZONE 2 (corres-
ponding to class 1 division 2 group D) or non-hazardous locations only.
Warning! - Operating unit (Valmet TCU) is suitable for use in non-hazard-
ous location only.
Warning! - Explosion Hazard - Substitution of components may impair
suitability for ATEX ZONE 2 area. In the case that components are replaced
into the sensor unit, sensor housing must be pressure tested according
to instructions in the manual to ensure suitability for ATEX ZONE 2.
Warning! - Explosion Hazard - Do not disconnect equipment unless power
has been switched off or the area is known to be non-hazardous.

Recycling and disposal
When sorted by material, nearly all parts of the device can be recycled.
A materials list is delivered with the device. Upon request, the manufac-
turer will provide more detailed instructions for recycling and disposal.
Used devices may also be returned to the manufacturer for recycling and
disposal against a separate fee.

Valmet Total Solids Transmitter

1. Introduction
1.1. Measurement principle
The operation of Valmet Total Solids Transmitter (Val-
met TS) is based on the measurement of microwave
propagation time.
Microwaves are a form of electromagnetic radiation,
and their propagation velocity, or flying time, is depend-
ent on the dielectric constant of the medium in which
they travel. The flying time is calculated as follows:
c = speed of light in vacuum
er = dielectric constant of the medium.
In water microwaves travel at a much slower speed
than in sludge. Thus the total solids content can be
calculated based on the time it takes the microwaves
to travel through the measured mass.
The advantages of this measurement method are
its independence on medium, insensitivity to flow rate,
and single-point calibration.
1.2. Parts of the device
The device consists of the sensor unit (Fig. 2 or 3) and
the TCU operating unit (Fig. 1).

2. Construction
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.

2.2. Sensor electronics
Sensor electronics of the FT model is shown in Fig. 3.
The sensor electronics board is installed between a
round cover and a base. The electronics contains a
microwave transmitter and receiver, and the electronics
for control, measurement and communciation.
When the electronics board is pressed on the base
plate, its snap-on connectors connect with the antenna
cable connectors on the base plate. Guide pins on the
base plate guide the connectors into position. The
temperature sensor, and the supply power and serial
communication lines from the TCU, are connected to
the connectors on the sensor electronics housing.
2.3. Transmitter Central Unit (TCU)
The TCU is the operating terminal and calculation unit
of the Valmet TS. It is operated by means of the keypad
and a four/line display. The TCU is delivered with a
shield attached to it (Fig. 2).
Connections:
– To sensor unit: operating voltage, RS485 serial
communication.
– To current outputs (2 passive outputs).
– To HART communicator (HART only in current out-
put 1).
– RS232 connection to a PC (for service purposes).
– Mains power.
