FLS1 High Pressure Flow Stand

The AA EDM FLS1 is a free standing, manual load, high pressure oil flow stand used to test the flow rates of diesel fuel injectors, fuel metering components and other parts requiring precise flows.

It is based upon our years of experience designing high production Microhole EDM machines with integrated flow test and adaptive control. With this design we have raised the bar for high pressure oil flow testing. It is designed for ease of use with intuitive touch screen controls along with simple fixture change over to handle many different parts. You create a simple program that selects the flow rate and pressure you need, or if you desire a pre test back flush, and the measurement flow direction. Then simply press the palm buttons and the test is executed.

The flow results are saved to a data log that can be sent to a USB thumb drive, a network or just saved locally. A 2-D bar code reader is available if you wish to scan the part and automatically select the flow program.
