Compressed air
Compressed air leak detection with IoT continuously measures flow, pressure and compressor load, revealing leaks and unused running times. This cuts the cost of one of the most expensive forms of energy in manufacturing.

IoT monitoring uncovers energy losses and leaks in compressed air
An LTE sensor from achtBytes measures the pressure in the compressed air system and reveals unnecessary compressor run times, excessive operating pressure and leaks, without any connection to company IT. In one case, the compressor started more than 20 minutes earlier than necessary.

Compressed air leak detection: measure losses, don't hunt for them
In the solution examples, flow sensors such as the SICK FTMg or sensors from SMC and ifm measure flow rate, pressure and temperature directly in the supply line to the machine. Via IO-Link masters, Modbus or MQTT, the values reach an edge device or a cloud platform, and for compressors also via cellular or NB-IoT. Leaks show up when compressed air flows although nothing is being produced, for example at weekends and on public holidays. Machine learning systems such as Emerson's evaluate the pressure curve of individual pneumatic cylinders and assign a leak to the right component. The same data serves as the basis for energy management in line with ISO 50001.
The examples come from the food, metal, automotive and home appliance industries, as leak detection within condition monitoring or energy monitoring. With a solution from in.hub, a food plant reduced the energy demand of its compressed air generation by 17 percent. STEGO Elektrotechnik used the achtBytes IoT platform to cut the morning warm-up of its compressors from 30 to 7 minutes. In its fully automated plants, BSH Hausgeräte has pneumatic leaks detected by a machine learning solution from Emerson and AIM, earlier than regular inspection rounds would find them.

Compressed air leak detection: frequently asked questions
How does compressed air leak detection with IoT work?
Sensors permanently measure flow and pressure in the supply lines and report the values to a platform. If compressed air flows while machines are idle, or consumption rises without higher output, this points to a leak. Machine learning systems detect deviations in the pressure curve of individual cylinders and show which component is losing air. This makes troubleshooting much faster than regular inspection rounds.
What is the cost of compressed air leaks?
Leaks are among the biggest cost drivers in compressed air supply. According to the solution examples, around 10 to 15 percent of industrial electricity consumption goes into generating compressed air, and in systems that have not been serviced for a while, up to 30 percent of the compressed air produced can escape through leaks. Overloaded compressors and machine faults add to this. After fixing the leaks it had found, one food plant saved 18.6 MWh per year.
What is a connected compressed air flow meter used for?
A connected compressed air flow meter shows how much compressed air each machine or line actually consumes. Sensors such as the SICK FTMg measure flow rate, pressure and temperature and transmit the values via IO-Link or Ethernet. This reveals leaks, load peaks and consumption per manufactured part, for example per aluminium wheel in a project by HEITEC and SMC. The data also feeds into energy management in line with ISO 50001.
Does IoT monitoring replace a compressed air leak detector?
IoT monitoring does not replace every manual check, but it changes when and where you search. Instead of walking through the hall with a leak detector at fixed intervals, the system reports a leak as soon as consumption deviates and shows in which area or on which machine it occurs. At BSH, the Emerson solution uncovers leaks much earlier than regular inspection rounds and shows where in the plant they occur.

Indoor air
Indoor air quality monitoring with IoT means sensors continuously record CO₂, fine dust, particles, temperature and humidity and report limit violations immediately. Operators protect employees, safeguard product quality and heat and ventilate according to demand.
Drinking water
Water network leak detection for drinking water continuously measures pressure, flow and consumption with IoT and reports deviations immediately. Utilities find leaks, pipe bursts and water theft sooner and lose less drinking water.
Groundwater
Groundwater monitoring with IoT measures levels automatically and transmits them by radio to a platform. Authorities, utilities, construction sites and businesses with their own well replace manual measurements and are alerted to critical water levels or pump faults.
Wastewater
Wastewater flow measurement, levels and water quality can be recorded with IoT directly at pipes, basins and discharge points. Operators see wastewater volumes in real time, respond faster to faults and meet reporting obligations without daily sampling.
Molten metal
In foundry melting and vacuum metallurgy, IoT continuously records the melt pool, fill level, temperature and pressure of molten metal. Deviations show up before a batch becomes unusable or a furnace runs empty.
Beer
In a commercial brewery, IoT sensors measure the density, temperature and material properties of the beer directly in production. Breweries see values such as sugar and alcohol in real time instead of drawing samples and waiting for the lab.
