Thermo-Anemometric Flow Meter IZMERKON TM 635
In modern industrial processes where the highest accuracy in dosing and accounting is required, specialized measuring equipment comes to the forefront. The thermo-anemometric flow meter IZMERKON TM 635 is a high-tech solution designed specifically for operation in small-diameter pipelines. This device provides precision flow measurement in laboratories, test benches, and high-tech production lines where the stability of metrological characteristics is critically important.
The main distinctive feature of the TM 635 thermal mass flow meter is the ability to obtain flow data normalized to standard conditions. The device provides data under normal conditions without the use of external pressure sensors, temperature sensors, or flow correctors. This approach significantly simplifies the integration of the device into existing networks and reduces the maintenance costs of the measuring unit. This makes the TM 635 thermal mass flow meter an ideal choice for transparent and reliable accounting.

General Information: Why Choose the Thermal Mass Method?
To understand the superiority of this technology, it is worth comparing it with traditional methods. A conventional volumetric flow meter records only the volume of gas, which strongly depends on pressure and temperature. In practice, this leads to significant accounting errors. In contrast, the thermal mass flow meter operates on the physical principle of heat dissipation.
The device sensor consists of two platinum thermoresistors. One measures the medium temperature, and the other is heated. The passing gas cools the heated element, and the device records the energy required to maintain thermal balance. The greater the mass of the passing gas (number of molecules), the more heat is removed from the sensor. Thus, the TM 635 thermal mass flow meter measures the amount of substance, which is its main distinctive feature.
This approach is especially relevant when a flow meter for nitrogen, argon, or helium is required. The density of these gases changes significantly under compression, but the TM 635 automatically accounts for these changes, providing flow data in normal cubic meters or liters per minute.
Applications in Industry and Science
The range of tasks solved by the TM 635 series mass flow meters covers the most critical areas:
