Thermal Mass Flow Meter IZMERKON TM 650
In the modern realities of the industrial sector, where production efficiency directly correlates with the accuracy of resource control, the correct choice of measuring instruments becomes a strategic task. If a reliable, accurate, and durable tool is required, then the IZMERKON TM 650 compressed air flow meter is exactly the solution that meets the needs of the most demanding industries: from metallurgy to the oil and gas sector.
This thermal anemometric flow meter represents a combination of advanced technologies in microelectronics and metrology. It is designed for direct measurement of the mass flow of gases in pipelines of various diameters. The main value of the device lies in its ability to provide ready data normalized to standard conditions, without the need to install bulky and expensive metering units consisting of separate pressure and temperature sensors.

Features of the TM 650 Thermal Mass Flow Meter
The TM 650 model stands out among competitors for its unique adaptability to extreme operating conditions. Unlike standard household or simplified industrial meters, this thermal mass flow meter is designed to operate under high pressures and temperatures while maintaining metrological stability.
Key design features:
- Highest temperature resistance. The standard version easily handles environments up to +150°C. For specific tasks (e.g., accounting for hot flue gases or steam in power engineering), a version capable of withstanding a colossal +450°C is available.
- Operation under critical pressure. The flanged design of the device allows measurements in pipelines with pressures up to 6.3 MPa. This makes the TM 650 indispensable in oil and gas chemistry and main gas pipelines.
- Installation flexibility. The device is equipped with an immersion probe that can be up to 1500 mm long. This allows the same type of device to be used on pipes with diameters from DN 25 to DN 2500 and even in rectangular air ducts.
- Resistance to contamination. Sensors made of stainless steel 316 are practically immune to corrosion and abrasive wear. The absence of moving parts guarantees that mechanical impurities in the gas will not cause jamming or breakage.
- Intelligent data processing. Built-in electronics perform complex algorithmic analysis, filtering out turbulence noise, which is crucial for obtaining reliable cumulative results.
Along with this device, you may also be interested in the following similar instruments:
- IZMERKON TM 600 — an excellent solution for standard diameters with convenient RS485 configuration.
- IZMERKON TM 635 — the optimal choice for systems requiring an integrated measuring section for maximum accuracy at low flows.
- VA 520 — a classic thermal anemometric air flow meter of the flow-through type for local consumption points.
- VA 500 — a universal immersion sensor for rapid pneumatic system audits.
General Information: How the Thermal Anemometric Method Works
Understanding the device's operating principle helps appreciate its advantages. Any IZMERKON series thermal anemometric air flow meter uses the law of thermal diffusion. Inside the protected probe tip are two reference platinum resistance thermometers (RTD).
The TM 650 microprocessor records the amount of energy required to maintain a constant temperature difference between the gas temperature sensor and the heated element. Since heat transfer directly depends on the density and mass flow of gas molecules, the device provides a direct result in kg/h or Nm³/h without external calculators.
Applications of the Device in Various Fields
This series of industrial compressed air flow meters is in demand in the following areas:
- Pneumatic audit and Energy service: detection of hidden leaks due to high sensitivity to low velocities.
- Oil and gas chemistry: measurement of flare gases, accounting for natural gas, methane, and associated petroleum gas at pressures up to 63 bar.
- Metallurgy: control of oxygen supply to converters and argon in steel secondary metallurgy installations.
- Water utilities and ecology: measurement of air volumes supplied to aeration tanks at sewage treatment plants.
- Food and pharmaceutical industry: accounting for nitrogen and carbon dioxide in hygienic stainless steel design.
- Aquaculture: ensuring oxygen balance in life support systems of fish farming enterprises.
