The T-Easic® FTS thermal flow sensor measures flow and temperature of liquids in accordance with the calorimetric principle. Available as an industrial variant with VISTAL® housing and display or as a hygienic stainless-steel variant, the T-Easic® FTS is suitable for a wide range of applications. Depending on the requirements, the sensor features two digital outputs for limit value monitoring, a pulse output for volume recording or an analog output for continuous recording of measured values. A special feature is integrated empty pipe detection for optimal dry-run protection in pumps. Parameterization can be done via IO-Link or the display. Media taught-in at the factory such as oil and water accelerate commissioning; other liquids can be calibrated quickly and easily.

At a glance
  • Flow monitoring and temperature measurement in one sensor
  • Optimized for water and oil; teach-in option of other liquids
  • IP 67/IP 69 enclosure rating and IO-Link 1.1
  • Industrial design in VISTAL® housing with 180°-rotatable OLED display
  • Stainless steel hygienic variant, completely CIP-/SIP-capable, process temperatures up to 150 °C


One sensor, two measurements.

The T-Easic® FTS thermal flow sensor offers flow monitoring and including empty pipe detection and temperature measurement in just one device. This means a single measuring point is sufficient for both measurements. This saves time during commissioning and reduces the risk of contamination to the bare minimum.

Versatile – flow monitoring and temperature measurement

Auf Basis des kalorimetrischen Messprinzips misst der Sensor Durchfluss und Temperatur von nahezu jeder Flüssigkeit.

Two housings – hygienic and industrial variants

The T-Easic® FTS is available in two variants. The hygienic variant with stainless-steel housing withstands the challenging conditions in CIP and SIP systems. The industrial version with rugged VISTAL® housing offers an OLED display and operating buttons to read the measured values directly on site.

Thanks to the two specific housing variants, the T-Easic® FTS can be integrated into a wide range of application environments and offers flow monitoring and temperature measurement in one device.

Solves a wide range of measuring tasks for pump monitoring and control

In many plants, transporting liquids with pumps is an important process step. If the pump does not work at the desired operating point, this can impair the process and the product quality and, in the worst case, lead to plant shutdowns. For example, if too little coolant is transported in machine tools, the workpiece can overheat and get damaged. To prevent this, the T-Easic® FTS flow sensor monitors and controls flows based on defined limit values.
Optimal pump protection thanks to empty pipe detection

The sensor detects the pipe as “full” as soon as its probe tip touches the medium and outputs this information as a switching signal. This is how pumps can be reliably protected against idling.

Reliable limit value and flow monitoring

The T-Easic® FTS features two push-pull digital outputs that can be configured either as a switching output for limit monitoring, a pulse output for volume detection or a digital input.

Automated measurement system via analog output or IO-Link

Process monitoring is simple and user-friendly thanks to continuous measurement using the optional analog output or IO-Link. The flow sensor can be parameterized via IO-Link or the display.

Clever and multifunctional – the T-Easic® FTS makes various tasks possible: Empty pipe detection, pump protection and monitoring, flow measurement, temperature measurement as well as volume detection and monitoring.

Save time and money thanks to quick and flexible installation

Sound details such as different probe lengths and practical T-connectors enable flexible mounting and quick commissioning of the T-Easic® FTS. Pre-calibration is also helpful for water and oil. Other media can also be taught in, which makes the sensor suitable for a wide range of applications.
The right probe length depending on the pipe size

Three different probe lengths allow for flexible adaptation to the respective pipe diameter. This makes it possible to integrate the T-Easic® FTS into a wide range of applications. This saves on storage costs.

Save time during mounting

Suitable mounting adapters and T-connectors are available for the most varied system conditions. Advantage of the T-connector: The probe tip is always optimally aligned in the center of the pipe.

Pre-calibrated and versatile teach-in options

Water and oil are taught in at the factory, other liquids can easily be added via teach-in.

Thanks to a wide range of probe lengths and practical mounting accessories, the T-Easic® FTS can be integrated flexibly into different applications.
