LPG (Liquefied Petroleum Gas) Flow meters LPG, CNG, LNG

LPG (Liquefied Petroleum Gas) flow meters are specialized instruments used to measure the quantity of LPG moving through a pipe, whether in its liquid or gaseous state. Choosing the right meter depends on your specific application, such as residential billing, industrial process control, or high-precision "custody transfer" during truck unloading. 

Common Types of LPG Flow Meters

• Coriolis Mass Flow Meters: Often considered the "gold standard" for accuracy (up to ±0.1%), these measure the actual mass of the LPG directly. They are ideal for high-pressure applications and scenarios where the LPG may be in a mixed state (both gas and liquid).
• Thermal Mass Flow Meters: These use heat transfer to measure mass flow without needing pressure or temperature compensation. They are highly accurate at low flow rates and commonly used for monitoring fuel consumption in industrial burners.
• Positive Displacement (PD) Meters: These mechanical meters use rotating components (like pistons or rotors) to capture and measure discrete volumes of fluid. They are rugged and often used in mobile applications like 
• Turbine Flow Meters: Use a rotating turbine to determine flow speed. They are cost-effective and compact but generally require a minimum flow rate to stay accurate and may need more maintenance due to moving parts.
• Diaphragm Gas Meters: Most common for residential and light commercial use, these measure the volume of gaseous LPG. High-pressure versions can handle up to 2 bar. 

Key Selection Factors

When selecting an LPG meter, industrial suppliers like Silver Automation Instruments or Burak Metering recommend evaluating: 

• Phase: Is the LPG liquid (e.g., filling a tank) or gaseous (e.g., feeding a furnace)?
• Accuracy: Do you need high precision for billing (0.1–0.5%) or just general monitoring (1.5–3%)?
• Pressure & Temperature: LPG density changes significantly with these factors, requiring meters that either measure mass directly or offer automatic compensation.
• Safety Certifications: Meters must meet standards like ATEX or CE for use in hazardous, flammable environments.
