One aspect of the invention provides a lubricator device for dispensing a lubricant to a lubrication point of a machine. The device includes an electric dispensing mechanism including an electronic control circuit. The control circuit includes an RF receiver for receiving control signals, e.g. signals incorporating a lubrication schedule to be adopted by the control circuit, and an RF transmitter for transmitting operational signals incorporating an ID code of the device and at least one operational parameter of the device. Such at least one operational parameter may include one indicative of an amount of lubricant dispensed or one indicative of an error condition. Another aspect of the invention provides a lubrication system including a plurality of lubricator devices, as referred to, and a computer in communication with them for monitoring their operation via operational signals received from them and for controlling their operation via control signals transmitted to them.
