AN ELECTRIC CIRCUIT FOR REGULATING FLOW OF FLUID TO A BATCH WITH AN ADJUSTMENT OF THE FLOW A PREDETERMINED INTERVAL PRIOR TO COMPLETION OF THE BATCH ABSTRACT OF THE DISCLOSURE A STORAGE CIRCUIT RECEIVES SIGNALS REPRESENTATIVE OF VOLTAGE PULSE TRAINS. A GENERATOR OF VOLTAGE PULSE TRAINS FEEDS A PREDETERMINED NUMBER OF VOLTAGE PULSES INTO THE FIRST CIRCUIT FOR STORAGE THE FIRST CIRCUIT GENERATES A SIGNAL TO STOP THE GENERATION OF THE FIRST PULSE TRAIN. A SECOND TRAIN OF PULSES IS GENERATED BY THE FLOW OF FLUID TO MAKE UP A BATCH OF THE FLUID. THE FIRST CIRCUIT IS ARRANGED TO GENERATE A SIGNAL TO A CONTROL VALVE FOR THE FLUID SUPPLY WHEN THE CIRCUIT HAS RECEIVED A NUMBER OF PULSES IN A TRAIN WHICH EQUALS THE TOTAL REQUIRED FOR A BATCH MINUS THE PREDETERMINED NUMBER OF VOLTAGE PULSES MANUALLY ESTABLISHED IN STORAGE, THE CIRCUIT THEN ESTABLISHES A SECOND SIGNAL TO THE CONTROL VALVE WHEN THE SECOND TRAIN OF PULSES EQUALS THE TOTAL NUMBER OF PULSES FOR EACH BATCH.
