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.

Controlling heating and cooling in a conditioned space utilizes a fluid circulating in a thermally conductive structure in fluid connection with a hydronic-to-air heat exchanger and a ground heat exchanger. Air is moved past the hydronic-to-air heat exchanger, the air having fresh air supply and stale air exhaust. Sensors located throughout the conditioned space send data to a controller. User input to the controller sets the desired set point temperature and humidity. Based upon the set point temperature and humidity and sensor data, the controller sends signals to various devices to manipulate the flow of the fluid and the air in order to achieve the desired set point temperature and humidity in the conditioned space. The temperature of the fluid is kept less than the dew point at the hydronic-to-air heat exchanger and the temperature of the fluid is kept greater than the dew point at the thermally conductive structure.

A valve positioner for use on a process control valve or valve assembly. The process control valve may include a pneumatic actuator and a valve having a closure member coupled with the pneumatic actuator and moveable relative to a seat. The valve positioner may couple to the pneumatic actuator to provide a pneumatic signal to set a position of the closure member relative to the seat. An accelerometer may couple with the valve positioner. The accelerometer may generate data in response to orientation of the valve positioner. In one implementation, the configurations can use this data to ensure proper visualization of data on a display. The data also permits the device to properly manage operating modes, like tight shut-off or fully-opened mode, that may prevail due to orientation issues that cause defects in a measured position for a closure member that regulates flow of material through the valve assembly.

The invention also relates to a process plant having a modular construction for the production of a chemical and/or pharmaceutical product having such a metering module (10) and to a method for controlling the temperature of a metering device (24) for metering liquids.

A heating, ventilation, or air conditioning (HVAC) system for a building includes HVAC equipment configured to provide heating or cooling to one or more building spaces and one or more controllers. The one or more controllers include one or more processing circuits configured to generate energy targets for the one or more building spaces using a thermal capacitance of the one or more building spaces to which the heating or cooling is provided by the HVAC equipment, generate setpoints for the HVAC equipment using the energy targets for the one or more building spaces to which the heating or cooling is provided by the HVAC equipment, and operate the HVAC equipment using the setpoints to provide the heating or cooling to the one or more building spaces.

A cleaning device includes a main body housing, a cleaning liquid tank, a pressure sensor and a flow controller. By arranging one or more pressure sensor on a gripping portion of the main body housing and movably fitting flow limiters of the flow controller with liquid outlets of the cleaning liquid tank, a control component of the flow controller drives the flow limiter according to a pressure signal transmitted by the pressure sensor, such that the flow limiting area of the flow limiter fitted with the liquid outlet is changed. As such, when gripping the cleaning device, a user can control the outflow of cleaning liquid by the pressure applied to the pressure sensor by hands during gripping, such that the liquid outflow meets the use requirement for each single squeeze. Accordingly, repeated squeezing and pouring can be avoided, and user convenience can be improved.

A system, apparatus and method of cleaning tubes of a heat exchanger or a tube bundle that includes disengaging the heat exchanger or bundle from a use-position in a process or a plant; moving the heat exchanger or bundle to a cleaning station remote from the use-position; positioning the heat exchanger or tube bundle in front of a cleaning apparatus; providing water jet cleaning equipment on the cleaning apparatus; responding to programming in a computing device and controlling the water jet cleaning equipment and a cleaning operation; providing a pattern of tube openings defined in an end plate of the heat exchanger or bundle to the computing device; actuating the water jet cleaning equipment with the computing device; and manually or automatically performing a cleaning operation with the water jet cleaning equipment under control of the programming of the computing device and by following the provided pattern of tube openings.
