Flow meter
Abstract
Abstract THIS FLOW METER INCLUDES MEANS FOR DYNAMICALLY CONVERTING THE FLOW OF A FLUID PASSING THROUGH A PATH PROVIDED THEREIN TO THE REVOLUTION OF A GEARED ROTARY CRANK SHAFT OF A MEASURING SECTION, A PULSE GENERATOR HAVING AN INDUCTION COIL, MOVABLE MAGNET CORE AND RAPIDLY RECIPROCATING MEMBER ASSOCIATED WITH THE MAGNET CORE AND URGED BY THE RESILIENT ACTION OF A SPRING, MEANS FOR INTERMITTENTLY ENGAGING THE RECIPROCATING MEMBER WITH THE GEARED ROTARY CRANK SHAFT SO AS TO ACCUMULATE, WHILE THE RECIPROCATING MEMBER IS INTERLOCKED WITH THE GEARED CRANK SHAFT. KINETIC ENERGY IS PRODUCED RESULTING FROM THE ROTATION OF THE GEARED CRANK SHAFT IN THE RECIPROCATING MEMBER IN ACCORDANCE WITH THE INCREASING MAGNITUDE OF SAID SHAFT ROTATION AGAINST THE SPRING ACTION AND THE KINETIC ENERGY IS PRODUCED AT THE MOMENT SAID INTERLOCKING IS RELEASED, PRODUCING PULSES. A COUNTER MEASURES THE PULSES SUPPLIED BY THE GENERATOR.
