Abstract: We need to make sure that water filters are safe and work properly. This is important for keeping our water clean and people healthy. If there are leaks or problems with the filters that we do not find they will not work well as they should and people could get sick.This project is, about making a machine to test water filters. The machine is called an automated Pressure Decay Test Bench. It uses a computer system to control everything. It is connected to a program called LabVIEW.The machine tests the water filter by filling it with air and then checking to see how fast the air leaks out over a certain amount of time. This helps us know if the water filter is working correctly. We use the water filter to make sure our water is clean and the machine helps us know if the filter is doing its job. The water filter is an important thing and the machine is helping us to keep it safe. When the pressure drops much we know there is a leak. This way we can find the smallest problems. We use an ABB PM556 PLC to automate things, which means people do not make mistakes. This also means we get the results every time and we can test things faster than if we did it by hand. We use LabVIEW to watch what is happening in time to get the data to see what it means and to store the results of the tests. The system has parts, like pressure transmitters, solenoid valves, manifolds and a compressor. These parts help us control the pressure precisely and measure it accurately. We use the ABB PM556 PLC and LabVIEW to make sure the pressure control and measurement system works correctly. Experimental results demonstrate that the developed test bench provides reliable, efficient, and repeatable leak detection, making it suitable for industrial quality control applications in water filter manufacturing.
