There are two ways to do this. The first way is to use a pressure gauge mounted at the end of the distribution system. By noting the pressure that the system maintains, a rise in pressure would indicate that one or more of the delivery lines are blocked, either the line itself or the control or meter unit. A decrease in pressure would indicate that there is a leak in the the delivery line at some point. The second way to verify delivery of the lubricant would be to install a sight valve, such as our ST series, into the delivery line between the control or meter unit and the lubrication point. This would allow visual indication of the lubricant being delivered to the lubrication point.
