To compensate for an event, equipment may require a power down sequence of a motor connected to a pump to prevent the pumping of servicing fluid at a high pressure, high pressure fluid may be required to be diverted to a reservoir or otherwise diverted from a wellhead, multiple pumping systems may require that pumping pressure be altered or adjusted or that flow rate be altered or adjust to manage or control the conditions to protect equipment or personnel at a site. Activating, adjusting or altering an operational characteristic of equipment by using a control system may automatically initiate the most efficient and effective mitigation steps for equipment at a site when condition is detected or predicted. Collecting and analyzing information from devices, components, sensors, control systems, other equipment or any combination thereof at a site by a master control system provides automated control of pressure sensitive conditions.

A method includes measuring a fluid pressure of fluid in a fluid supply line of an infusion pump. The fluid pressure includes a motor pressure and a patient pressure. The method also includes determining the patient pressure. The determining includes removing, by an adaptive filter, to remove the motor pressure from the measured fluid pressure. The removing includes generating a predicted motor pressure based on the current of the motor, generating an error signal based on a comparison between the predicted motor pressure and the measured fluid pressure, and removing the motor pressure from the measured fluid pressure when an error value indicative of the error signal is less than an error threshold. The method also includes adjusting, based on the patient pressure, a setting of the infusion pump. Related methods and articles of manufacture, including apparatuses and computer program products, are also disclosed.

A reciprocating pump includes: a housing with a suction port and a discharge port; a reciprocated member disposed in the housing to form a pump chamber and reciprocable such that fluid is sucked into the pump chamber through the suction port and then discharged from the pump chamber through the discharge port; an actuator configured to reciprocate the reciprocated member; and a pressure gauge with a pressure receiving portion, configured to detect pressure of the fluid in the pump chamber through the pressure receiving portion, and coupled to the reciprocated member to be reciprocated by the actuator integrally with the reciprocated member.

A reciprocating pump includes: a housing with a fluid channel that includes a pump chamber; a reciprocated member that is disposed in the housing to form the pump chamber, and reciprocable for suction and discharge of fluid; an actuator configured to reciprocate the reciprocated member; and a pressure gauge with a pressure receiving portion, configured to detect pressure of the fluid in the fluid channel via the pressure receiving portion. The housing includes an inner wall facing the fluid channel, and a flexible, membranous portion placed continuously next to the inner wall to face the fluid channel. The pressure gauge is attached to the housing such that the membranous portion is sandwiched between the pressure receiving portion and the fluid channel.

The present invention relates to a method of operating a pump generating a flow of a fluid with a pressure, the method comprising operating the pump with a pump speed S satisfying the equation S=S.sub.simple(1+COR(t)); wherein S is the pump speed, S.sub.simple is the pump speed disregarding any compression and/or expansion of the fluid, t is a time, and COR(t) is a time dependent correction function; wherein the time dependent correction function COR(t) is a product of a corrective amplitude A.sub.cor and a time-dependent function f(t), i.e., COR(t)=A.sub.cor.Math.f (t); and wherein the corrective amplitude A.sub.cor is set by means of a measure for the flow and a measure for the pressure. The present invention also relates to a corresponding use, a pump, a pump system and an HPLC system.
