How to keep contaminants out of your gas pressure calibration system

Combating Contaminants That Threaten Pressure Calibration System

Liquid Contaminants – Fluid Trap

A Fluid Trap is the best way to control liquid contamination in your gas calibration system. This design uses a siphon to force the liquid out of the gas and collects it in a chamber for easy removal after the system is depressurized.

A Fluid Trap that is rated to 3000 psi (210 bar) helps to seperate out moisture as well as providing a volume that will collect any unwanted liquids. A Fluid Trap that has a quick-connect lid that can be easily emptied so the user will never have to worry about getting liquids in their pressure calibration device again.

Gas Contaminants – Block and Bleed Valve

Natural gas high in sulfur, often called “sour” gas, can be a challenge. If you have problems with sour gas and want to keep it out of your calibration system use a Block and Bleed Valve.

This valve will allow you to vent off the contaminated gas prior to it reaching the pressure calibration equipment.

By installing the Block and Bleed Valve at the point where the hose connects to the device under test, you keep the sour gas or other contaminants out of your hoses and avoid damage from high sulfur content gas.

Ralston Instruments can provide all the products that you need to keep your calibration system free of the contaminants. By proactively using fluid traps andblock and bleed valves you can extend the life of your equipment and reduce your maintenance costs.
