Chongqing Chuanyi MFR-C Insertion Thermal Gas Mass Flowmeter
MFR-C
The Chongqing Chuanyi MFR-C Insertion Thermal Gas Mass Flowmeter utilizes advanced thermal dispersion technology to measure gas mass flow directly without requiring separate temperature or pressure compensation. Engineered with an all-metal welded structure, a high turndown ratio (up to 1000:1), and online hot-pluggable insertion capabilities, it delivers low pressure loss and high reliability for large-diameter industrial pipelines and ventilation ducts.
The Chongqing Chuanyi MFR-C Insertion Thermal Gas Mass Flowmeter is a precision instrument engineered for accurate, direct mass flow measurement of industrial gases across large-diameter pipes and HVAC ventilation ducts. Operating on the thermal dispersion principle, the MFR-C uses dual platinum RTD sensors to measure heat loss, converting it directly into mass flow data without the complexity of external pressure or temperature transmitters.
Core Architectural & Performance Advantages:
-
Direct Mass Flow Measurement: Measures gas mass directly, eliminating calculation errors caused by dynamic fluctuations in medium temperature or pressure.
-
High Turndown Ratio: Delivers exceptional measurement sensitivity and an ultra-wide turndown ratio of up to 1000:1, capturing both extremely low and peak flow rates accurately.
-
Hot-Pluggable Insertion Design: Features a convenient insertion structure that supports online installation and extraction, minimizing maintenance downtime and simplifying plant operations.
-
Negligible Pressure Loss: Designed with a streamlined probe profile that creates virtually no pressure drop across the pipeline, optimizing energy efficiency in high-volume air and gas distribution networks.
-
Rugged All-Metal Construction: Built with durable materials including 304 stainless steel, 316L, or Hastelloy options to withstand corrosive environments and ensure long-term stability.
Flexible Configuration & Integration: The MFR-C series offers versatile power supply choices (24V DC or 220V AC) and supports both integrated and remote transmitter configurations. This flexibility allows operators to monitor ventilation and process gas values centrally while easily adapting to high-temperature or confined installation spaces.
