Meter units are oil proportioning devices for cyclic systems. Each outlet of a lubricating system is controlled by a meter unit. The lubricator in the system dispenses known amounts of oil to the distribution network and meter units deliver this oil in varying amounts to the bearing points.
Meter units type “F” must be used with all cyclic type lubricators (cannot be used with continuous lubricators). Meter units feed in one direction only. This is indicated by arrow stamped on body.
