Demand flow regulators are used with gas detection instruments and analyzers that utilize a pump to draw the gas. The regulator controls the exact amount of gas that flows through the instrument pump which can be set as required. It is used mainly for docking stations that have their own sample draw system.
SGI's demand flow regulators are the easiest solution for calibration gas requirements as they eliminate the need for flow meters and simplify gas detection calibration training. They also help save expensive calibration gases due to their capability to control the flow of gases as required.
SGI's demand flow regulators, as per their design and precision manufacturing, are only set to open under a vacuum of a 3-inch water column which gives the desired flow rate of 0-3 L/Mn.
The regulators can be used for a range of corrosive and non-corrosive gases and can be manufactured in stainless steel or nickel-plated brass as per the requirement. These are available in both standard C10 connection and high-pressure NPT connection.
