Safe and Precise Light Hydrocarbon & LPG Density Measurement Testing Equipment Under Pressure

DESCRIPTION / TECHNICAL SPECIFICATIONS

This specialized testing apparatus provides a reliable and safe method for determining the relative density of volatile light hydrocarbons, including Liquefied Petroleum Gases (LPG). Accurate density measurement is critical for quality control, commercial transactions (custody transfer), and compliance with product specifications. The instrument is precisely engineered to allow hydrometer testing on samples that would otherwise evaporate at normal atmospheric temperature and pressure, providing crucial data for professionals in the oil and gas industry.

The core of the system is a pressure hydrometer cylinder designed in accordance with the ASTM D1657 standard. This cylinder is constructed from a robust, transparent acrylic resin, which allows the operator to clearly and safely view the thermohydrometer reading inside while the sample is held under pressure. With a specific density measurement range and an integrated thermometer, this tool ensures the data collected is comprehensive and accurate, reflecting the true conditions of the fluid being tested.

Safety is a top priority in this instrument's design. The cylinder is hydraulically tested to 1.8 bar and is equipped with a stainless steel mesh safety guard for added protection. The rugged structure is reinforced by metallic headers coupled with six stainless steel tie rods, ensuring the vessel's integrity even when handling pressurized samples. A pressure gauge with a 0 to 24 bar scale is also included for continuous monitoring of the internal pressure.

This device serves as a complete solution for gas processing laboratories, refineries, and storage facilities. Every component, from the neoprene gaskets to the precision pin cocks, is selected to guarantee a leak-free and reliable performance. By utilizing this instrument, laboratories can consistently produce accurate and defensible density data, which is essential for volume calculations, calorific value determination, and ensuring safety in the handling and transportation of light hydrocarbons.
