US Patent 7970558 Fluid flow monitor and control system

A method for monitoring a signal from a cycle switch mounted to a lubrication divider block system. The method comprises receiving a signal from a remotely located cycle switch that is mounted to a divider block, wherein the cycle switch is responsive to the motion of a piston in the divider block. The number of cycles of the cycle switch are counted based on the signal from the cycle switch. The number of cycles is stored in a computer readable medium and the amount of lubricant used is calculated based on the number of cycles. The amount of lubricant used is then stored in the computer readable storage medium.
