Thermal Gas Mass Flowmeter for Air, Gas, and Steam with Temperature and Pressure Compensation

Overview

The JC-010 Thermal Gas Mass Flowmeter is an innovative solution engineered for precise and reliable measurement of gas flow across a wide range of industrial applications. By leveraging advanced thermal technology, this flowmeter delivers highly accurate measurements, even in challenging environments where temperature, humidity, and pressure can vary. Utilizing a proprietary flow data modeling algorithm and fuzzy logic control, the JC-010 ensures stable, precise readings by compensating for fluctuations in temperature and humidity, making it ideal for use in various industries such as oil and gas, power generation, and environmental monitoring.

Equipped with intelligent microprocessors and analog-to-digital conversion chips, this flowmeter boasts a wide range ratio of 100:1, enabling it to measure low flow rates with minimal pressure loss. Its ability to measure mass flow directly eliminates the need for additional temperature and pressure compensation, offering exceptional sensitivity to low flow rates and making it highly effective for applications involving large pipe diameters. Designed for ease of installation, it requires low straight pipe lengths and ensures minimal operational downtime.

However, the JC-010 is not recommended for measuring liquids or gases with high water vapor content, especially steam, which may interfere with its accurate operation.

Principle:

The thermal mass flowmeter operates based on the thermal diffusion principle, where the heat loss of a heated object when gas flows over it is proportional to the flow rate. The instrument uses two RTD sensors (resistance temperature detectors)—one acts as a heat source, while the other measures the temperature of the flowing gas. The temperature difference between these sensors correlates with the flow rate, allowing the flowmeter to produce a linear output signal for accurate flow measurement.
