Flow Control Methods (Meter In, Meter Out, Bypass)

This lecture presents flow control methods for fluid power systems. We will learn to recognize meter in, meter out, and bypass/bleed off flow control methods used to control both the extension and retraction speed of a cylinder. Additionally, we will recognize advantages, disadvantages, and appropriate circumstances for the application of each flow control method.

Ankush, yes, I'm using MS OneNote for the lectures. I use Camtasia screen capture software. Glad you're making use of these videos. Stay in touch because I'll be slowly updating the hydraulics and electrical control of hydraulic systems playlist. My plan is to improve the audio and editing of the old ones I have at the cgcclive channel and include a bunch more advanced applications and illustrated example problems.

Awesome. Do you have videos for meter in meter out flow control on variable piston pump systems?

[timrudloff]

17:23 I dont understand why the pressure is rising on the upstream valve. Can someone help me here?

[kozstandsya]

Doesn't a restricted orifice also reduce pressure? Would meter in flow restrictions be giving the cylinder a weaker "push" than a meter our?

Jim, Most hydraulic excavators have the lift cylinder mounted to the body of the machine and the rod attached up on the boom arm. I have noticed on some very large machines, the manufacturer has mounted them upside down with the rod attached to the body and the cylinder attached to the boom. What would be the reason for doing this, there are many factors involved other than just basic hydraulics such as possible damage to rod chrome, or oil leaks in sensitive areas. Thanks for your time and effort in your series.

Can you tell me which software application you're using to draw diagrams? OneNote?

Great video Jim! Just wanted to say that choose different thumbnails for your videos. That would really help people find out what your video actually contains. I myself neglected your videos before landing on this video! So.. Just suggesting

Hi Sir, I would like to ask if it is ideal to install dual FCV in opposite direction in one line? to do both meter in and out function. Thank you
