Abstract
A remote control fluid dispensing system is disclosed comprising a fluid dispenser and electrical pump means for pumping fluid from the dispenser at a dispensing station. Pulse generating means are provided at the dispensing station for generating DC pulses in metered response to the dispensing of fluid. Electrical to light energy transducer means and light to electrical energy transducer means electrically insulated from but optically coupled with the electrical to energy transducer means are provided at a control station. Electrical circuit means are further provided for coupling the pulse generating means with the electrical to light energy transducer means and for coupling the electrical pump means with a source of current at the control station. Display means are further provided at the control station coupled with the light to electrical energy transducer means for displaying metered dispensing of fluid information generated by the pulse generating means.
