Liquid Petroleum Gas Density Testing Device (Pressure Hydrometer Method)

DESCRIPTION / TECHNICAL SPECIFICATIONS

Introducing a specialized laboratory instrument, the Liquefied Petroleum Gas (LPG) Density Tester, which operates using the Pressure Hydrometer Method. This device is a crucial solution designed for the high-accuracy determination of density or relative density of liquefied petroleum gas and other light hydrocarbons. With full compliance to fundamental international industry standards such as ASTM D1657, ISO 3993, and SH/T0221, this instrument is an indispensable tool for refineries, storage terminals, and quality inspection laboratories to ensure product specifications are met, for custody transfer purposes, and to guarantee safety.

Safety and robustness are the cornerstones of this instrument's design, which is purpose-built to handle volatile, pressurized samples. All valves are crafted from high-grade stainless steel (1Cr18Ni9Ti) capable of withstanding pressures up to 4MPa. The main test cylinder is made of sturdy, transparent organic glass, allowing the operator to safely observe the testing process visually, and is securely sealed at both ends with metal end plates and neoprene gaskets. This instrument is designed for safe operation with samples having a vapor pressure of up to 1.4MPa.

Accuracy in density measurement is highly dependent on precise temperature control, and this instrument excels in that aspect. The unit is equipped with an integrated heater bath system that includes an electric heater, a high-efficiency agitator, and an automatic temperature adjustment system. The sensitive and responsive digital temperature controller ensures the test temperature can be stably maintained at either 15°C or 20°C with a strict accuracy of ±0.2°C. Furthermore, the system is also equipped with a compressor refrigeration method for effective cooling, making it a complete and reliable thermal system.

Designed for efficient and reliable operation, every component is selected for optimal performance. The 1250 r/min agitator ensures temperature uniformity throughout the bath with low noise levels. The clear digital display provides real-time temperature information, allowing for easy monitoring. Overall, this LPG Density Tester provides a complete, safe, and highly accurate solution for routine quality control testing and specification compliance in the demanding environment of the petroleum and gas industry.
