High-Temperature Digital Oxygen Thermal Mass Flow Meter Factory RS485 Compressed Air and Natural Gas for Mass Flow Measurement

Product Description

 

 

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.

Key Features

• High-Stability Platinum RTD Sensors: Provides exceptional temperature compensation and ensures reliable, long-term accuracy.

• Proprietary Balanced Structure Packaging: Enables medium temperature compensation, improving stability across varying environmental conditions.

• Advanced Algorithms: Offers high linearity, repeatability, and accuracy, even in fluctuating conditions.

• Wide Range Ratio of 100:1: Ideal for low flow rates and large pipe diameters, making it versatile for a range of industrial applications.

• No Moving Parts: This flowmeter design features negligible vibration impact, ensuring durable and low-maintenance operation.

• Low Straight Pipe Length Requirements: Installation is simple with 5-10D of straight pipe needed, minimizing installation complexity.

• Independence from Medium Temperature and Pressure: The JC-010 is unaffected by temperature and pressure fluctuations, ensuring consistent performance.

• Temperature and Humidity Compensation Algorithms: Supports media temperatures up to +300°C and is calibrated to account for high humidity conditions.

• Dust and Particle Insensitivity: The flowmeter is resistant to dust and small particles, making it suitable for continuous, online operation and reducing maintenance requirements.
