LPG sampling

Mechatest delivers operator safety and friendly LPG sampling systems that allows for sampling in a safe and controlled environment. To take under high pressure LPG samples the conventional way is not only inefficient, but in the case of this dangerous media, humans and the environment are subjected to high safety risks, the Mechatest LPG samplers are the safe and efficient solution for LPG sampling under high process pipeline pressure and temperature. The Mechatest LPG sampling systems are based on gas cylinder sampling principle, a perfect solution for LPG sampling from tanks, containers, pipeline and reactors, to take representative samples of LPG gas in high pressure applications. 

The problem with LPG sampling is that it wants to change state if the pressure varies. This requires a sample system and a sample cylinder with a safe outage tube. 


Propane is bought and stored in a liquid form (LPG), and thus fuel energy can be stored in a relatively small space. Compressed natural gas (CNG), largely methane, is another gas used as fuel, but it cannot be liquefied by compression at normal temperatures, as these are well above its critical temperature. Propane is a by-product of natural gas processing and petroleum refining, it is commonly used as a fuel. Propane is one of a group of liquefied petroleum gases (LP gases). The others include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof.

Propane is a three-carbon alkane with the molecular formula C3H8. It is a gas at standard temperature and pressure, but compressible to a transportable liquid.

Risk-free LPG sampling with Mechatest equipment

Protecting both the operator and the equipment is the most important consideration when developing LPG sampling systems. First of all, increasing safety is a matter of simplicity. The easier the system is to operate, the smaller the chance of accidents gets. At Mechatest, we make sure that our systems are easy to operate by using single levers, easy-to-read pressure gauges, and a simplified system for replacing the needles or nozzles. While taking the sample, excess emissions are redirected back into the system, thus preventing the built up of pressure.
