A method of sensing parameters in a fluid distribution system includes the steps of receiving, at a monitoring device, fluid parameter information from a sensor in a fluid distribution system; collecting, by the monitoring device, sampling data of the fluid parameter information from the sensor based on predetermined criteria; receiving, by the monitoring device, a request to collect transient data from the sensor; collecting, by the monitoring device, transient data of the fluid parameter information from the sensor based on predetermined criteria; and communicating the sampling data and the transient data to another device. An apparatus includes a monitoring device including a power source, an antenna, and a parameter sensing portion configured to monitor a parameter of a fluid distribution system; and a sensor array connected to the monitoring device

Apparatus for providing variable speed pump control in a hydronic pump system having a system flow and pressure requirement, featuring a signal processor or processing module configured to: receive signaling containing information about a system characteristic curve, a system flow and pressure requirement for the hydronic pump system, and real time changes by a pump operator to at least one control parameter to adjust the performance of the hydronic pump system; and determine corresponding signaling containing information about a design/redesign of at least one pump, system or control curve to adjust the performance of the hydronic pump system to correspond with the system flow and pressure requirement of the hydronic system, based upon the signaling received.

A computer-implemented method includes controlling water separation in a hydrocarbon stream flowing through a separator train including one or more separator vessels located upstream of a dehydrator by manipulating a demulsifier flowrate added to the separator train by: receiving data from a real-time process test of the separation train, estimating model fit parameters to the data to generate a water separation profile (WSP) correlating water draw-off and demulsifier flowrate for the separation train, determining a maximum and a minimum demulsifier flowrate from the WSP, receiving, from an operator, a separation performance for a target water separation value entering the dehydrator downstream from the separator train, and adjusting the demulsifier flowrate according to the WSP to achieve the target water separation entering the dehydrator.

Systems and methods for monitoring system health of a well cementing operation are disclosed. A well cementing system includes several fluid pathways and holding/mixing containers. A series of sensors monitors the status of the fluid pathways and the holding/mixing containers. There are redundancies in the fluid pathways, and a preferred order in which the fluid pathways are used. Under normal conditions the fluid for the cementing operation is moved from place to place via the most desired pathway. If the sensors detect a fault, the next-most desired fluid pathway is used. If there are no available fluid pathways, an alarm is issued.

A dehumidification system includes a compressor, a primary evaporator, a primary condenser, a secondary evaporator, and a secondary condenser. The secondary evaporator receives an inlet airflow and outputs a first airflow to the primary evaporator. The primary evaporator receives the first airflow and outputs a second airflow to the secondary condenser. The secondary condenser receives the second airflow and outputs a third airflow to the primary condenser. The primary condenser receives the third airflow and outputs a dehumidified airflow. The compressor receives a flow of refrigerant from the primary evaporator and provides the flow of refrigerant to the primary condenser.

A control system for an operable system such as a flow control system or temperature control system. The system operates in a control loop to regularly update a model with respect at least one optimizable input variable based on the detected variables. The model provides prediction of use of the input variables in all possible operation points or paths of the system variables which achieve an output setpoint. In some example embodiments, the control loop is performed during initial setup and subsequent operation of the one or more operable elements in the operable system. The control system is self-learning in that at least some of the initial and subsequent parameters of the system are determined automatically during runtime.

A water management method for controlling at least one operational parameter of at least one water control device, wherein the operational parameter is associated with water used by the water control device, the method comprising: sending, from an electronic controller of the water control device, operational data associated with the operational parameter to an embedded electronic device; receiving, at the embedded electronic device, the operational data, and developing control data based on the received operational data and sending the control data to the electronic controller; and receiving, at the electronic controller, the control data and controlling the operational parameter of the water control device based on the received control data.

A sanitaryware system may include sensors to determine a status or condition of one or more sanitaryware fixtures in the sanitaryware system and perform a particular function, such as, for example performing a flush, closing the flush valve and/or angle stop, sending an alert, initiating a service ticket. The sanitaryware system may automatically perform the function. The sanitaryware system may communicate the status or condition to an internet connected device and/or user, the device may perform the function or may instruct the sanitaryware to perform the function. The sensed information, sanitaryware system status or condition, and/or initiated response may be logged and monitored to improve the overall efficiency and operation of the sanitaryware system and the sanitaryware fixtures within the system.
