Flow Meters for Compressed Air and Gas
Do You Know How Much Compressed Air and Gas Your System Is Wasting?
Leaks, inefficiencies, and unmonitored usage in compressed air and gas systems can quickly increase energy costs and decrease performance. Without accurate measurement, it is difficult to identify problems, cut waste, or control expenses.
SUTO iTEC has more than 20 years of experience tackling these challenges. Our high-precision flow meters for compressed air and gases give you the data you need to identify waste, improve efficiency, and make informed decisions.
SUTO iTEC Flow Meters
We supply two types of flow meters: thermal mass flow meters for dry, clean gases and pitot tube meters for wet air at compressor outlets. Below is a quick overview; our experts are ready to help you choose the right model.
Why Measure Compressed Air Flow and Consumption?
Why It Matters
In many industries, compressed air is essential, yet its usage is often overlooked. This results in wasted energy, higher costs, and missed optimization opportunities.
The breakdown shows how compressed air is typically used and lost:
-
45–50% Production – energy invested in generating compressed air
-
25–30% Leaks – invisible losses through leaks in the system
-
10–15% Artificial demand – unnecessary consumption due to excessive pressure or misuse
-
5–10% Inappropriate uses – when compressed air is applied where other energy sources would be more efficient
Altogether, up to 30% of compressed air is wasted, driving up operational costs and reducing efficiency.
Key Benefits of Measurement
- Energy Savings: Optimizes air consumption to minimize waste and reduces operating costs.
- Leak Detection: Reduce downtime and enable prompt repairs by spotting leaks and inconsistencies early.
- System Health Monitoring: Take proactive steps to remain ahead of performance issues and make sure your compressed air system runs reliably for a longer period.
- Performance Evaluation: Use benchmark system measurements to guarantee constant quality and gradually increase efficiency.
- Strategic Planning: Capacity planning, upgrading of systems, and creation of scalable systems that can accommodate future needs using accurate data insights

Different Flow Meter Types at SUTO ITEC and where to install
SUTO iTEC offers a range of flow meters that meet diverse industrial needs. Our flow meters are built to deliver accurate measurements, even under extreme conditions. There are two main types of flow meters:
1. Thermal Mass Flow Meters
Thermal mass flow meters are highly effective for monitoring compressed air and gas flows in controlled environments.
- Ideal for: Dry, clean air or technical gases such as nitrogen, oxygen, or carbon dioxide.
Advantages:
- Easy to install. No extra temperature- or pressure compensation needed.
- Long-term stable measurements.
- Minimal maintenance requirements.
2. Pitot-Tube Flow Meters
These sensors are designed for wet air applications and are ideal for measurements before filtration, directly at the compressor outlet.
- Ideal for: Wet and humid air (higher water content), often found in compressor outlets.
Advantages:
- No drying or filtration is required prior to the point of measurement.
- Perfect for energy audits and compressor performance evaluations.

How to Choose the Right Flow Meter for Your System?
Selecting the flow meter for compressed air and gas most suited for your application depends on several factors. SUTO iTEC’s experienced team can help guide you through the selection process to find the right flow meter for your application.
Type of Air or Gas
- Is it clean and dry, or dirty and wet?
- Thermal mass flow meters are ideal for dry gases, while pitot-tube flow meters excel in wet conditions.
Pipe Size and Flow Rates
-
Choose a meter that matches your system’s pipe diameter and expected flow rates.
Installation Considerations
-
Ensure there’s enough space for installation and check if insertion under pressure is required.
Output Signals and Compatibility
-
Look for interfaces that integrate seamlessly with your system, such as Modbus or 4…20 mA analog.
What to Do With Your Data?
Data Collection and Analysis
Once collected, your flow data becomes a valuable asset. You can connect SUTO iTEC flow meters to the S331 Data Logger or S551 Portable Data Logger to store and analyze data locally, or send it to the S4M Smart Monitoring Software for remote analysis.

FAQs – Common Questions
What is the difference between flow and consumption?
Flow shows the current rate (e.g. m³/h), while consumption is the total usage over time (e.g. m³). Both are important to understand system performance and costs.
How do I choose the right flow meter?
Key factors:
- Pipe size
- Flow range (min and max)
- Gas type
- Pressure and temperature
- Installation conditions
Correct sizing is critical for accurate results. Learn more about how to choose the right flow meter in our 10 Tips Checklist.
What is the difference between insertion and inline flow meters?
Insertion flow meters are installed into the pipe and are ideal for larger pipe sizes or retrofit installations.
Inline flow meters come with a measuring section and offer higher accuracy under controlled conditions, typically used for smaller pipe sizes.
How accurate are compressed air flow meters?
Accuracy depends on proper installation, sizing, and stable conditions. Thermal mass flow meters offer high accuracy without needing pressure or temperature compensation.
Can I install a flow meter without stopping production?
Yes. Insertion-type flow meters can be installed under pressure using a ball valve, allowing installation without system downtime.
What if the compressed air is wet or contaminated?
For wet or hot air (e.g. directly after the compressor), pitot tube flow meters are recommended. Thermal mass flow meters are best suited for dry, clean air.
Can flow meters help reduce energy costs?
Yes. Compressed air systems often have significant losses. Flow measurement helps identify inefficiencies, leaks, and unnecessary consumption.
Do flow meters require maintenance?
Maintenance is generally low, especially for thermal mass sensors.
However, periodic checks and calibration ensure long-term accuracy, especially in harsh environments.
