Seeing is Knowing
A glance is all it takes to know if the correct amount of liquid is flowing to your spray nozzles or planter openers.

When the liquid is flowing equally the balls hover at the same level. A ball that is lower than the others indicates the flow is too low due to a restriction or blockage; a ball that is higher than the others indicates the flow is too high due to a leaking fitting or hose.

Individual columns clip together so you can gang as many or as few columns as you need.

Exclusive O-ring seal and joint clip system is easy to assemble and service.
You can monitor up to three spray tips per column.
Metering orifices can be inserted to control flows ranging from 0.004 - 8.0 USGPM.
