Got a call today about a liquid level alarm on the receiver, and when I arrived it was really low sitting at about .5%. Checked the graph on the LL and it was fluctuating between .5% and 1% since last Sunday 6/19. This seemed odd to me since usually it would bottom out at 0% with any kind of leak, and it held .5-1 for the entire week?
This was on a supermarket rack system, and what really made me scratch the old noggin was before this it was running 39% and dropped sharply and held .5-1% for a few hours, and then jumped back up to 39%. When it bottomed out at .5-1% the second time it stayed that way for an entire week. This is my first foray into the supermarket side of things, and it seemed odd.
