An LPG (Liquefied Petroleum Gas) dispenser is a specialized piece of equipment used in LPG filling stations for filling liquefied petroleum gas into the cylinders of gas vehicles. Here are some key points about LPG dispensers:
Main Features
Dual Display: Many LPG dispensers feature a double-sided LCD display that shows information such as the volume of gas being dispensed, the unit price, and other relevant data.
Accurate Measurement: They are designed to measure the amount of LPG dispensed accurately, with a measurement accuracy of around ±0.25% to ±1.0%.
Gas and Liquid Phase Separation: The dispensers are capable of separating gas and liquid phases during the dispensing process.
High Efficiency Filter: Equipped with high-efficiency filters to ensure the cleanliness of the dispensed gas.
Preset Function: Allows operators to preset the desired amount of gas to be dispensed.
Power-on Self-test: Performs a self-test upon power-on to ensure reliable operation.
Safety Features: Includes features such as automatic valve closure when pressure or flow exceeds set values, no-flow shutdown to protect owner interests, and explosion-proof ratings (e.g., Exdib II AT4) to ensure safe operation in potentially hazardous environments.
Data Storage and Monitoring: Capable of storing and querying gas data, monitoring filling process temperatures, flow rates, and other parameters.
Technical Parameters
Flow Range: Typically between 5 L/min to 70 L/min or 10 L/min to 60 L/min, depending on the model.
Maximum Working Pressure: Ranges from 1.8 MPa to 2.5 MPa.
Working Environment Temperature: Usually between -20℃~50℃, -30℃~55℃, or -40℃~55℃, accommodating various climate conditions.
Power Supply: Typically AC220V±10% or AC220V±15% 50/60Hz.
Weight and Dimensions: Vary depending on the model and whether it is a single-gun or double-gun dispenser.
Applications
LPG dispensers are primarily used in LPG filling stations where they are essential for the safe and efficient filling of liquefied petroleum gas into the cylinders of vehicles such as buses, trucks, and other industrial or commercial vehicles that use LPG as a fuel source.
In summary, an LPG dispenser is a crucial piece of equipment in LPG filling stations that ensures the accurate, safe, and efficient filling of liquefied petroleum gas into vehicle cylinders.
