<p>The invention relates to a device and a method to determine the delivery rate or mass flow rate of material conveyed by a high density liquid piston pump (10) through a delivery line (24). The exact determination of the above mentioned variables is achieved by mounting the delivery cylinder (12) in a housing (30) with radial and axial slack and suspending it on at least one weighing cell (36) forming one piece with the housing.</p> |
