Flow sensor with energy measurement

The FTMg energy consumption flow meter measures gas flow and temperature as well as the process pressure, making it a cost-saving multi-talent. With high measurement dynamics and low pressure loss, it measures non-corrosive gases with extreme efficiency. The contrast-rich color display enables easy operation of the FTMg and allows for representation of several measured values as a process diagram. Internal data logging over seven days and integrated static evaluation help detect even the smallest leaks in a pneumatic system. PoE also enables simple web-based connection to a PC or a cloud to make energy consumption more transparent. All measurement data can be transmitted via IO-Link or with switching and analog signals.

Saving costs effectively with data transparency

Compressed air is one of the most expensive types of energy, which is why energy efficiency and energy transparency are playing an increasingly important role in factory automation. The investment costs, for example for procuring powerful compressors, are enormous. To save on follow-up costs, you must ensure loss-free operation of compressed air systems. The FTMg (Flow Thermal Meter for gases) thermal flow sensor stands for efficient energy management in accordance with DIN EN ISO 50001. It helps system operators to detect leaks in the compressed air system early on and plan maintenance work.

The FTMg offers an integrated data monitoring function and automatically saves the measurement data of the last seven days. This allows changes and fluctuations in energy consumption to be reliably detected. With its data transparency, the sensor provides efficient assistance in finding leaks in compressed air systems and helps minimize energy loss as well as save money.

For intelligent, automated monitoring and analysis of compressed air consumption, SICK has a complete digital solution with the combination of the FTMg sensor, the Monitoring Box FTMg digital service and the Telematic Data Collector (TDC) gateway.

Reliable flow monitoring in compressed air systems and pneumatic applications

Measurement of 8 parameters in one sensor, including energy in kWh

Easy operation thanks to integrated web server

Ready for Industry 4.0 – MQTT and OPC UA ensure optimal cloud connectivity

Optimize energy efficiency and increase cost efficiency by detecting and preventing unnecessary input of energy and leaks

Countless mounting options and simple handling

The FTMg is characterized by its light and compact construction. This makes installation easy, even with limited space. The display, which can be rotated in 90° increments, means that reading measured values is always convenient, regardless of the installation position of the sensor in the pipeline. Various reference standards according to DIN or ISO can be easily selected via the FTMg menu. Even individually defined reference values are easy to set using the device. Configurable outputs also allow for simple adaptation to the desired application.

Flexible configuration – setting of different reference standards according to DIN or ISO possible

Flexible installation thanks to light and compact construction

Intuitive operation via large, contrast-rich OLED display with plain text

Support operational efficiency with quick, easy installation and intuitive operation

Continuously monitor and efficiently control compressed air systems – using the FTMg Monitoring Box from SICK

Compressed air systems can be responsible for consuming a significant amount of energy. Monitoring and analyzing these systems enable companies to sustainably optimize their usage of compressed air: in switch-on and switch-off management, compressor control and peak load management. To help companies cut costs, SICK offers a digital solution comprising the sensor FTMg, the gateway TDC and the digital service Monitoring Box. The solution displays deviations from normal operation to facilitate quick identification of defects, leaks and wear and tear of mechanical components.
Cut costs

Identify overconsumption and inefficiencies in compressed air systems and boost overall profitability. Data-driven profitability calculations make it possible to measure and indicate potential cost savings.

Green production

By monitoring compressed air, companies reduce their carbon emissions and energy consumption, resulting in a positive impact on the environment and contributing to production sustainability.

Raise production efficiency

Decentralized, continuous monitoring of compressed air enables companies to identify deviations and cost drivers. This allows them to reduce unnecessary energy costs and increase production efficiency. Data-driven decision-making supports companies in sustainably improving efficiency.

Reduce service effort

Need-based maintenance saves companies time, effort and therewith money. Alerts and dashboards tailored to the application provide transparency and the opportunity to exclude unplanned maintenance.

Sustainably reduce energy consumption through intelligent, automated monitoring and analysis of compressed air consumption.
