Product Description

Product Description

Thermal Gass Mass Flowmeter

Thermal flowmeters, ingeniously designed around the principle of thermal diffusion, stand out with their remarkable versatility. Boasting a broad measurement range ratio, these devices are impervious to on-site pipeline vibrations and require minimal straight pipe sections for installation. Their exceptional functionality has garnered increasing market favor, making them indispensable across a multitude of sectors.

CHARACTERISTIC

1, Experience the convenience of hassle-free installation and maintenance, complemented by bidirectional detection capabilities. Our flowmeters excel with anti-vibration protection, offering up to 24 points of precise flow measurement.
2, Benefit from precise analog output calibration through our advanced multi-point non-linear curve correction, ensuring accuracy and reliability.
3, Enjoy an impressive wide-range ratio of 100:1, ensuring adaptability and precision across diverse applications.
4, Seamlessly switch between flow and temperature detection with our intuitive display, providing comprehensive data at your fingertips.
5, Capable of measuring small flows in large diameters, our flowmeters are adept at detecting even the slightest leaks.
6, Our cutting-edge 'double balance structure' encapsulated sensors employ proprietary technology for enhanced performance and reliability.
7, Master the elements with our proprietary algorithms designed for high humidity and temperature conditions. Detect direct mass flow at medium temperatures up to 300℃ without the need for temperature and pressure compensation.

PRINCIPLE

Thermal flowmeters operate on the sophisticated principle of heat diffusion. As fluid passes a heated object, the dissipated heat correlates proportionally with fluid flow rate. Our flowmeters utilize two precision RTDs—one as a heat source, the other to measure fluid temperature. The resulting temperature difference is linearly linked to flow rate and converted into a precise flow signal through advanced microelectronic technology.
