Mass flow measuring system

Claim 1

APPARATUS FOR MEASURING THE MASS RATE OF FLOW OF A FLUID, COMPRISING: A CONDUIT FOR TRANSMITTING FLUID FROM A SUPPLY ZONE TO A RECEIVING ZONE; A PORTION OF SAID CONDUIT BEING MOUNTED FOR TRANSLATIONAL MOVEMENT IN A DIRECTION LATERALLY OF ITS LONGITUDINAL AXIS; FORCE APPLYING MEANS TO APPLY A TRANSLATIONAL FORCE IMPULSE IN SAID LATERAL DIRECTION TO SAID CONDUIT PORTION AND TO THE FLUID MOMENTARILY CONTAINED THEREIN, SAID FORCE APPLYING MEANS INCLUDING A POWER SOURCE AND DRIVE LINKAGE CONNECTED BETWEEN SAID POWER SOURCE AND SAID CONDUIT PORTION; A FORCE TRANSDUCER IN SAID DRIVE LINKAGE ADAPTED TO SENSE THE FORCE APPLIED TO SAID FLUID AND TO TRANSMIT A SIGNAL PROPORTIONAL TO THE DENSITY OF THE FLUID; MEANS CONNECTED TO SAID CONDUIT PORTION AND COMMUNICATING WITH THE FLUID FLOWING THERETHROUGH TO SENSE A PARAMETER OF THE STEADY STATE FLOW AND TRANSMIT A SIGNAL PROPORTIONAL TO THE PRODUCT OF THE DENSITY AND THE SQUARE OF THE VOLUMETRIC FLOW RATE OF SAID FLUID; A MULTIPLIER UNIT FOR MULTIPLYING SAID SIGNALS; AND A SQUARE ROOT UNIT FOR DERIVING THE SQUARE ROOT OF THE PRODUCT OF SAID MULTIPLIER UNIT; SAID SQUARE ROOT CONSTITUTING THE MASS RATE OF FLOW OF SAID FLUID.
