How Air Stopper Works and What It Does
The AIR STOPPER takes long established principals of fluid dynamics and applies them in a new and financially rewarding application.
The Problems with Water There are a number of potential problems inherent in water delivery and usage that can impact your water consumption and water costs. The majority of these concerns revolve around water system pressure (PSI) and flow rate (GPM). Water fixtures in your building are typically designed for water pressure of no more than 65 PSI. The water delivered by your municipality (city) often has much higher pressure. This results in more water being pushed through your fixtures, leaking through seals & gaskets that are designed for 65 PSI and increased maintenance costs. Along with the volume of water passing through your water meter is a volume of air. The lower the water pressure the more volume the air will have. The problem is that 99% of water meters measure only volume, regardless if that volume is liquid or gas.
Water meters are designed to be accurate within a specific flow range (GPM). If the flow exceeds this range it can cause the meter to over-spin. City water pressure can fluctuate significantly causing surges and pressure drops. This will cause the meter to over-spin and damage water systems & equipment. Surges also occur anytime you go from no flow (static) to flow (dynamic),such as when you turn on and off a hose
How the AIR STOPPER Works Air Compression: The AIR STOPPER air compression benefit works on all single jet, multi jet, and turbine category positive displacement meters. These make up over 99% of all water meters in use. The science is based upon Boyle's Law regarding gas pressure and volume and Le Chatelier's Principal of volumetric dynamics. The AIR STOPPER is installed in your water line on your side of the meter as close to the meter as possible. The variable spring loaded plunger maintains a constant pressure on the oncoming water supply. This backpressure manifests itself into a high pressure point on the other side of the water meter. When air reaches this pressure point, the air becomes compressed and no longer maintains its volume. It passes by the water meter in this compressed state until after it passes through the AIR STOPPER and soon returns to its original uncompressed state. The AIR STOPPER does NOT remove the air, it just compresses it so the water meter can't measure it. A common example of entrained gasses is shaking up a soda bottle. The AIR STOPPER VALVE is like the bottle cap keeping the system pressurized. The gasses are in there but you can't see them until you remove the cap, and neither can your water meter. You won't notice any difference in the water coming into your facility, but you will notice that your water meter is now spinning less. SEE INSTALLATION VIDEO
