Product Description

Product Description

Thermal Gass Mass Flowmeter

Thermal flowmeters, crafted with precision and innovation, are designed based on the sophisticated principle of thermal diffusion. These devices boast a remarkable measurement range ratio, robust resistance to pipeline vibrations, and minimal installation requirements for straight pipe sections, making them the preferred choice in the market. This versatility allows them to be employed across various industries with unparalleled efficiency.

CHARACTERISTIC

1, Benefit from effortless installation and straightforward maintenance with our bidirectional detection. Equipped to withstand vibrations up to 24 points, our flow measurement technology ensures reliability and precision.
2, Experience enhanced accuracy with output analog calibration that utilizes multi-point non-linear curve correction, ensuring exceptional measurement precision.
3, Marvel at an extensive wide-range ratio of 100:1, delivering unmatched flexibility and adaptability for diverse applications.
4, Achieve simultaneous flow and temperature detection with seamless display switching, elevating your operational efficiency and data visibility.
5, Capable of measuring large-diameter small-flow scenarios, our technology excels in detecting leaks, offering reliable performance in critical applications.
6, Our proprietary 'double balance structure' encapsulated sensors leverage advanced technology to deliver accurate and stable performance.
7, Harness proprietary high humidity and high temperature algorithms for direct mass flow detection at medium temperatures up to 300 ℃. This eliminates the need for temperature and pressure compensation, simplifying operations.

PRINCIPLE

The thermal flowmeter, ingeniously designed on the principle of heat diffusion, detects flow rates by measuring the heat dissipated when fluid passes through a heating object. Featuring two standard-grade RTDs—one as a heat source and the other for fluid temperature measurement—this innovative sensor capitalizes on the linear relationship between temperature difference and flow rate. Through advanced microelectronic control technology, this relationship is translated into a precise linear output flow measurement signal.
