Let's talk about the flow meter
« on: April 05, 2013, 05:15:59 PM »

Does anyone really know what and how this thing works? There is a small component soldered into this very small circuit board, that is then inserted into a small bodied valve body that includes a wheel that spins and apparently gives feedback to the ccu via of the flow meter circuit board. Here is something I ran across. These appear to be the same except one has a mounting tab, and a significant price difference.check it out.

Must have a small generator in it that puts out a current while the water is flowing.

 LG flow meters use a magnetic pick up... Fwiw

*****

A small magnet is attached to the "wheel" inside the Flow Meter.

Each revolution of the "wheel" (Hall Effect Sensing) is a signal---which is sent to the Main Board.

In this manner---the Main Board can "count" the number of revolutions---for correct water fill.

If too little or too much water enters the appliance (within a specified/allowed time period) an error message is usually displayed---indicating that a problem/malfunction has occurred.
