Claim 1
Independent Claim
182 words
A SYSTEM FOR CALIBRATING A METER OF THE TYPE FOR MEASURING THE TOTAL AMOUNT OF FLUID FLOW BY PRODUCING OUTPUT PULSES AT A RATE CORRESPONDING TO THE RATE OF FLUID FLOW COMPRISING MEANS TO INDICATE THE START OF A TEST INTERVAL AND INDICATE THE END OF SAID TEST INTERVAL WHEN A PREDETERMINED AMOUNT OF FLUID HAS PASSED THROUGH THE METER TO BE CALIBRATED AFTER THE START OF SAID TEST INTERVAL, MEANS TO COUNT THE METER PULSES PRODUCED BY SAID METER TO BE TESTED OCCURRING DURING SAID TEST INTERVAL, AND MEANS TO MEASURE THE LENGTH OF THE INTERVAL BETWEEN THE START OF SAID TEST INTERVAL AND THE NEXT OCCURRING METER PULSE AFTER THE START OF SAID TEST INTERVAL, THE LENGTH OF THE INTERVAL BETWEEN THE FIRST TWO METER PULSES OCCURRING AFTER THE START OF SAID TEST INTERVAL, THE LENGTH OF THE INTERVAL OCCURRING BETWEEN THE END OF SIAD TEST INTERVAL AND THE NEXT OCCURRING METER PULSE AFTER THE END OF SAID TEST INTERVAL, AND THE LENGTH OF THE INTERVAL BETWEEN THE FIRST TWO METER PULSES OCCURRING AFTER THE END OF SAID TEST INTERVAL.
