Abstract: A viscous fluid is dispensed precisely using a fluid pump, control valves configured to control both the air inlet and outlet of the fluid pump, an optional adjustable regulator further controlling the air outlet, and a control circuit that opens and closes the control valves. To further increase the precision, additional control valves can be used to control liquid inlet and outlet of the fluid pump.

Abstract: An analysis system may determine a discharge pressure or a suction pressure using a single measurement sensor coupled to a computing device. The measurement sensor may include a pressure sensor or a strain sensor. In some aspects, the pressure sensor may generate a pressure signal representing the total pressure in a chamber of the pressure pump. The computing device may apply an envelope filter to the pressure signal to determine the discharge or suction pressure in the chamber from the pressure signal. In other aspects, the strain sensor may generate a strain signal representing the strain in the chamber. The computing device may determine the discharge or suction portions of the strain signal and may correlate the portions with a predetermined internal pressure for the pressure pump to determine the discharge or suction pressure in the chamber.

Abstract: The invention relates in particular to measuring the delivery rate of a positive displacement pump comprising at least one piston (3) driven with reciprocating movement in a chamber (2), which chamber is connected to an inlet circuit (4) via an inlet valve (5) and to an outlet circuit (6) via a delivery valve (7). The number of cycles performed by the pump in unit time are counted, and simultaneously its volumetric efficiency is measured, thereby enabling its real delivery rate to be deduced. Its volumetric efficiency may be measured by means of position sensors (17, 18) detecting the closure and opening instants of the delivery valve, with another sensor determining the instants at which the piston (3) passes through its end positions.

Abstract: A method for a system having a plurality of primary fluid sources and a fluid output with a common pump includes halting pumping of a first fluid, isolating the common pump from the fluid output and the primary fluid sources, connecting an inlet of the common pump to a solvent source and an outlet of the common pump to a waste fluid dump, actuating the common pump first in a pumping mode, then in a recirculation mode, and then in a flush mode, connecting an inlet of the common pump to a second primary fluid source, and an outlet of the common pump to the output line, and starting pumping mode pumping of a second fluid from the second primary fluid source through the output line.
