Next, you install the included flow valve (adjustable from drip irrigation to stream) and timer for your garden hose, and your raised bed is ready for watering.
The machine takes the input of "velocity" in inches or millimeters per second, or cubic inches or millimeters per second, and converts it to some type of electronic signal to control a flow valve or drive motor to push the screw at a velocity.
The underflow may be avoided by adding a pressure-independent flow-regulating valve (i.e., the auto flow valve) in each parallel loop, but this will increase the cost of the piping system.
This new approach exploits the inherent advantages of the axial flow valve trim configuration to deliver superior durability and higher erosion wear performance.
