Immersion Type Thermal Mass Flow Meter IZMERKON TM 450
Effective management of energy resources at an enterprise begins with accurate measurement. If pneumatics or gas lines are used in production, then a compressed air flow meter becomes not just an instrument, but a tool for direct savings. The modern market offers many solutions, but the immersion thermal mass flow meter IZMERKON TM 450 stands out among them due to its reliability and ease of installation.
Essentially, this device determines the mass flow of gas based on the principle of heat transfer. Unlike methods that measure volumetric flow, no additional pressure and temperature sensors are required here — the device provides ready data on mass flow or volume normalized to standard conditions. This significantly simplifies the measurement process and reduces the likelihood of error.

Features and Advantages of the Thermal Anemometric Flow Meter
When it comes to choosing measuring equipment, the thermal anemometric flow meter IZMERKON TM 450 is chosen for its unique design. The main advantage is the absence of moving parts. This means there is nothing in the device to wear out, jam, or break due to mechanical impurities in the flow.
Main advantages of the model:
- Direct mass measurement: the result does not depend on fluctuations in pressure and temperature of the working medium.
- High sensitivity: the device detects even the smallest leaks, operating in a velocity range from 0.1 m/s.
- Minimal pressure loss: the immersion probe has a small diameter and practically does not create obstacles for the gas flow.
- Wide dynamic range: the ratio of minimum to maximum measurable flow is 1:1000.
- Fast response: reaction time is only 1 second, which is critical for dynamic production processes.
- Simple installation: probe installation is possible on pipelines with diameters from DN 40 to several meters.
Devices with similar characteristics
Along with this device, you may be interested in the following similar instruments, which also solve the tasks of controlling air/gas flow in industry:
- VA 500 — a popular European flow sensor with RS 485 Modbus-RTU interface.
- VA 520 — an insertion flow meter for stationary compressed air lines with high accuracy.
How a Modern Thermal Mass Flow Meter Works
The IZMERKON TM 450 operates based on the calorimetric measurement method. Inside the probe, there are two thermistors. One acts as a reference sensor for the medium temperature, and the other is heated by electric current. The passing gas flow cools the heated element.
The thermal mass flow meter analyzes the power consumed by the heater, which is directly proportional to the mass flow. This approach eliminates the influence of gas density, making the thermal anemometric air flow meter an ideal choice for systems where pipeline pressure may vary unstably.
Thanks to intelligent electronics, the TM 450 automatically processes data and transmits it to the upper-level control system via standard outputs: analog 4-20 mA, pulse, or digital RS 485 (Modbus RTU).
Applications of the Industrial Compressed Air Flow Meter
Typical tasks for using the IZMERKON TM 450:
- Compressor stations: measuring the total volume of produced air and monitoring compressor efficiency.
- Food industry: accounting for nitrogen, carbon dioxide, or air consumption on packaging lines.
- Chemical and petrochemical industry: monitoring process gases in large diameter pipelines.
- Metallurgy: controlling air supply to burners and furnaces.
- Ventilation and HVAC systems: accurate measurement of air flow velocities in main air ducts.
Industrial compressed air flow meters are often purchased for energy audits, as the immersion type installation allows the device to be installed through a ball valve without stopping air supply to consumers.
Technical Specifications and Properties of the Device
The versatility of the IZMERKON TM 450 flow meter is confirmed by its operational parameters. The device represents a reliable solution for long-term use in harsh industrial conditions.
| Parameter | Value |
|---|---|
| Measured medium | Compressed air, nitrogen, oxygen, argon, carbon dioxide, etc. |
| Velocity range | From 0.1 to 100 m/s |
| Accuracy | ±1.5% of the measured value |
| Medium temperature | Up to +220°C |
| Maximum pressure | Up to 1.6 MPa (submersible), up to 4.0 MPa (flanged) |
| Interfaces | 4-20 mA, Pulse, RS 485 (Modbus RTU) |
| Probe material | High-quality stainless steel |
The presence of a digital Modbus RTU interface allows reading not only the current flow rate but also the accumulated value (counter), as well as the medium temperature, eliminating the need to install extra fittings on the pipe.
Where to buy a compressed air flow meter and what is its price?
IZMERKON TM 450 offers an optimal balance: it is professional equipment that is significantly more affordable than many imported counterparts with similar build quality.
The IZMERKON TM 450 device is often available in stock in Saint Petersburg. This significantly reduces delivery time to any region of Russia and CIS countries. To get accurate pricing information, it is necessary to prepare a technical specification indicating the gas type, pipe diameter, and required output signals.
Investing in accurate measurement is the first step towards cost transparency. Using reliable tools like the TM 450 ensures that every cubic meter of compressed air is under control.
