Wireless network system for dispensing lubricating liquid

A system for delivering a preset volume of fluid, such as oil, includes a master control station (1) and one or more metering devices (8) communicatively linked through a wireless communications network. The master control station (1) provides command signals to enable dispensing of a fluid from the metering device (8) and provides a preset amount of fluid to be dispensed. The metering device (8) is manually activated by a manually-operated lever (14), and is thereafter latched in an open position to dispense lubricant. The amount of lubricant dispensed is metered until the predetermined amount of lubricant is dispensed. After the preset amount is dispensed, the metering device (8) is latched in a closed position, preventing further dispensing until the metering device (8) is again enabled by the master control station (1).
