This Proportion-Air leak test device was designed to fill and maintain pressure in a PUT (Part Under Test). Here we are performing a fuel tank leak test with flow measurement. In this drawing a 16 gallon automotive fuel tank is leak tested at 5.00 psig.
The device uses a high flow digital valve and proportional valve to rapidly fill the large volume. The remote sense line measures the pressure and device shuts off the high flow valve when set point is achieved. Proportional valve maintains set pressure. If leak is present, the flow meter detects the flow rate and PLC records it.
Although this leak test device is not a standard product, it is one example of the many custom solutions we can help you build to fit your unique needs. Please reach out to us for more information.
