Thermal Mass Flow Meter IZMERKON TM 470 — Compressed Air Flow Meter
Energy resource accounting ceases to be just a formality and becomes a tool for real savings, especially when it comes to expensive technical gases. While immersion sensors are often used for large pipelines, for small and medium diameter pipelines where maximum accuracy is important, the IZMERKON TM 470 compressed air flow meter is the ideal choice.
This device is a thermal anemometric insertion (flow-through) type flow meter. Unlike immersion models, the TM 470 is supplied already integrated into a measuring section (pipe) with flange or threaded connection. This eliminates installation errors related to incorrect sensor positioning in the flow and guarantees the highest measurement accuracy immediately after installation.
If you need to request additional technical documentation for the product or require consultation, contact the specialists at IZMERKON. Engineers will help select the required diameter of the measuring section and type of connection.
Key Features of the TM 470 Model
The main distinctive feature of this device is the presence of a calibrated measuring section. Why professionals choose this model:
- Elimination of installation errors: The sensor is factory-installed in the correct position and at the required depth inside the measuring section.
- Cost savings: No additional installation of pressure sensors, temperature sensors, and calculators is required, thus reducing maintenance and calibration costs.
- Extremely wide dynamic range: Ability to detect both minimal flow and peak loads with high accuracy.
- No moving parts: The design contains no turbines or impellers, making the device resistant to wear and vibrations.
- Compactness: Perfectly suited for installation in limited space conditions of workshops or compressor rooms.

Operating Principle and General Information
The TM 470 operates on a calorimetric principle. Two high-precision thermal sensors are placed in the flow: one measures the medium temperature, and the other is heated by current to a fixed temperature difference.
The passing gas absorbs heat from the heated sensor. The electronics instantly compensate for the heat loss by increasing the heating current. The consumed power is directly proportional to the mass flow. That is why devices of this type do not require external pressure and temperature correctors — they immediately provide data normalized to "standard" conditions.
Industrial Flow Meter Application Areas
The device is effectively used in the following fields:
- Oil and Gas: Monitoring gas flows in extraction and processing complexes.
- Energy Audit: Conducting precise measurements to identify losses and optimize compressor operation.
- Automotive Industry: Monitoring consumption on assembly lines and in paint booths.
- Aquaculture: Accurate dosing of oxygen or air supply in life support systems.
- General Industrial Use: Universal accounting of compressed air and a wide range of gases.
