LF500 Series Thermal Gas Mass Flow Meter

The LF500 series gas mass flow meter is specifically designed for small-diameter, low-flow gas measurement and process control. It adopts highly reliable flow sensors and features a compact size, making it ideal for installation in tight spaces.

This meter is suitable for measuring non-corrosive dry gases. Key advantages include:

• Near-zero pressure loss
• Low cost
• Easy installation (no temperature/pressure compensation required)
• Capable of displaying standard flow and mass flow
• Can replace flow meters based on differential pressure, positive displacement, or area principles.

Key Features of LF500 Series Gas Mass Flow Meter

• High sensitivity (detects extremely low initial flow rates)
• Equipped with an LCD display and setting buttons: simple operation, direct reading, and display content can be rotated according to installation orientation for easy viewing
• Stable zero-point flow
• High stability across the full measurement range
• High precision and excellent repeatability over the full range
• Low power consumption and minimal sensor wear
• Fast flow response
• Flexible installation (no restrictions on pipeline orientation)

Application Fields of LF500 Series Gas Mass Flow Meter

With its high precision, wide turndown ratio, and ability to directly measure gas mass flow, this compact thermal gas mass flow meter is widely used in multiple industries:

Industrial Process Control

• Petrochemical: Used for flare gas emission monitoring and measurement of hydrogen, nitrogen, oxygen, etc. The sensor is not prone to clogging and supports online plug-in cleaning.
• Power & Metallurgy: Measures primary/secondary air flow in power plant boilers, and gas flow in blast furnace coal injection/coke ovens. Plug-in installation is convenient (no straight pipe requirements).
• Food & Pharmaceutical: Monitors fresh air supply in food processing and hot air flow in bottle sterilizers (designed to sanitary standards).

Precision Measurement & Research

• Laboratory-grown diamonds: Precisely controls gas flow during chemical vapor deposition (CVD) or high-pressure high-temperature (HPHT) processes to ensure diamond growth quality and efficiency.
• High-purity gas measurement: Used for high-purity gas measurement in the electronics industry and laboratories (sensors are highly polished, no need for temperature/pressure compensation).

Environmental Protection & Energy Monitoring

• Water Treatment & Environmental Protection: Measures air flow in sewage treatment aeration tanks, and monitors flue gas and emissions (resistant to dirt/dust, truly zero pressure drop).
• Energy Accounting: Improves flow measurement accuracy in environmental protection and energy accounting scenarios, providing reliable data support.

Other Fields

• HVAC Systems: Monitors the operation of ventilation and air conditioning systems to improve efficiency and support fault diagnosis.
• Semiconductor Manufacturing: Plays a key role in gas flow measurement for semiconductor processes.
