2 Safety information
2.1 Intended use
The T-Easic® is a flow sensor for liquids (defined in section 11) that operates on the
basis of the calorimetric measuring principle. It converts the flow rate and temperature
of the medium into an electrical signal, thereby providing the following measurands:
•Velocity (absolute)
•Velocity (relative)
•Volume flow
°Volume
°Temperature
The information about the flow rate and average temperature of the liquid is shown on

3.2.2 Control elements (industrial version only)
The sensor is controlled using the display and the operating buttons (industrial version
only).
A detailed description of the buttons and their functions can be found in see "Delay
Mode Q1", page 43.
NOTE
Both versions of the T-Easic® can be programmed using SICK SOPASET via the IO-Link
1.1 communication interface.
Information on IO-Link can be found in see "Operation", page 25.
3.3 Product features and functions
Principle of operation
The T-Easic FTS (Flow Thermal Switch) monitors the flow rate of liquids (e.g. water, aque‐
ous media, oil, etc.).
This measurement method is based on the calorimetric principle. The sensor measures
the cooling effect of the liquid flowing past the heated measurement probe. The higher
the flow rate of the liquid, the greater the cooling effect on the heated probe.
The sensor has two configurable digital outputs (Q1 and Q2) for flow and temperature.
Q1 can also be used for empty pipe detection. The sensor can detect whether there is
medium at the sensor tip and thereby detect an empty pipe.
The Q1 digital output also has an IO-Link interface (see see "Operation", page 25).

Q2 can also be used as a pulse output or digital input.
Depending on the electrical version (see "Type code", page 9), Q2 can also be used as
an analog output.
Fields of application
The T-Easic® is particularly suitable for measurement tasks relating to coolant circuits,
pumps, heat exchangers, leak monitoring for process lines, dry-running protection for
pumps, as well as monitoring the oil in hydraulic systems, the lubrication of wind
turbines, and hydraulic circuits. Due to its high temperature resistance, the T-Easic® is
also suitable for use in SIP (Sterilization in place) processes.

5 Mounting
5.1 Installation conditions
When installing the sensor, the system must be de-pressurized and the pipe in which
the sensor is to be installed must be empty.
For flow and temperature measurement, the inserted probe must always be completely
enclosed by the medium. If the sensor is used for empty pipe detection, the sensor
detects whether there is medium at the sensor tip and can thereby detect an empty
pipe.
The minimum insertion depth 3 of ≥12mm must be adhered to.
The cutting ring of the process connection adapter 1 must be ≥25mm away from the
probe tip 2 to avoid damage to the sensor element.
The sensor probe should be positioned in the middle of the pipe and must not be in
contact with the pipe wall.
A minimum distance of ≥10mm from the tip of the probe to the pipe wall must be
maintained 4.
At medium temperatures above 100°C, the distance between the bottom of the
housing and the top of the process connection adapter must be at least 25mm 5.
NOTE
If a Sick process connection adapter is used (see see "Accessories", page 68, the
60mm probe cannot be used at process temperatures above 100°C. This is because
the separation distances cannot be maintained.

Remounting the process connection adapter
1. Insert the probe with the mounted compression fitting into the process connec‐
tion. When doing so, make sure that the sealing surfaces are clean and there is no
damage on the surface.
2. Tighten the coupling nuts finger tight. Then tighten them using an open-end
wrench (width across flats 16) until you feel a sharp increase in the force to
be applied (approx. 1/4 turn). While doing so, hold the body of the fitting with a
second open-end wrench (width across flats 27).
5.7 Mounting in a T-piece
Use only original T-pieces from SICK. These are available as accessories (see see
"Accessories", page 68).
When mounting in these T-pieces, use the sensor variants with a permanently pre-
mounted clamping ring (see see "Type code", page 9 position 4).
During installation, insert the sensor with pre-assembled clamping ring into the T-piece
until the clamping ring is seated in the nozzle. Align the sensor so that the arrow on
the bottom shell of the sensor points in the direction of flow. Hold the T-piece in place
while tightening the coupling nut until there is noticeable resistance. Slightly tighten the

NOTE
Removal of the sensor with pre-assembled clamping ring from the T-piece is carried
out in the same way as described in see "Removing and remounting the process
connection adapter", page 17.
5.8 Mounting the hygienic process adapter
For hygienic applications, the sensor must always be combined with the hygienic proc‐
ess adapter. Installation must always be carried out in such a way that the installation
space around the installation is self-draining. That is,the process medium must be able
to flow off completely under the influence of gravity only.

EHEDG-certified installations are only possible using the process connections listed in
the EHEDG Position Paper. For this purpose, special seals or connection systems must
be used, which also comply with the relevant EHEDG Position Paper. These seals are not
included with delivery.
NOTE
Furthermore, for EHEDG compliant installations, the conditions described in the EHEDG
Position Paper must be adhered to. Particular care must be taken to ensure that the
prescribed conditions in the dead zone are met, see figure 11.

1. Insert the probe of the sensor into the hygienic process adapter (P/N 2093548). If
you perform a rotary movement in addition to the axial movement when inserting
the measuring probe, the sensor can be inserted more easily. Adjust the adapter
to the correct height (see see "Installation conditions", page 13). For optimum
measurement accuracy, make sure that the arrow on the bottom shell of the
sensor is aligned in the direction of flow (see see "Probe alignment to the flow
direction", page 15)
2. Hand tighten the coupling nut until the probe can no longer be turned by hand or
moved axially in the connection.
