Pressure Readings: Why Location Matters

We’ve always known that pressure readings are important – they are our best way to gauge if chemicals are mixing properly (at the same viscosity). If A and B side pressure measurements are equal, you’ll get a better mix and therefore a higher yield. Balanced pressures are also a reliable way to gauge ratio if your proportioner is not equipped with flow meters.




What happens in any proportioner is simple, the machine heats chemical to a setpoint, and builds pressure to a setpoint. When you pull the trigger on the gun, the pressure in the hose drops and the machine works to build the pressure back up. Measuring pressure at the machine is very important, but it doesn’t tell the whole story. There are several very important reasons to also take pressure measurements down the hose near the gun.


Troubleshooting


When you take pressure measurements at the proportioner and near the gun, you can get a clear picture of what is happening as chemical flows through your machine, down the hose, and all the way to the gun. This allows you to pinpoint gun blockages, leaks, and other technical issues, allowing you to quickly identify and fix equipment problems.


Better Chemical Atomization


Great chemical atomization typically results in better physical properties and typically better yields. Chemical atomization is determined by tip size, impingement point, and pressure. Pressure at the proportioner can be very different than pressure 200’+ down the hose. The best way to know that the chemical mix is at the maximum potential is to measure at the gun.


Uniform Pressure


Since pressure near the gun reacts to a trigger-pull well before pressure at the machine, an Akurate Dynamics proportioner intuitively starts building up pressure the moment of trigger-pull. This makes the Delta CPS much more reactive to pressure changes, resulting in fewer pressure drops and spikes, and no pulsations in pressure.


Safety


It's important to measure pressure not only at the proportioner, but also at the gun to avoid the risk of chemical exposure and injury. A pressure reading only at the proportioner, can fail to capture dangerous levels of pressure build up elsewhere in the system. Pressure readings at multiple points within the system reduces these risks and allows you to see the whole picture when assessing your equipment.
