witch) monitors the flow rate of liquids (e.g., water,
aqueous 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 switching outputs (Q1 and Q2) for flow and tempera

ture. 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 switching output also has an IO-Link interface (see
).
Q2 can also be used as a pulse output or digital input.
Depending on the electrical version (

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.
