The present invention is about a volume-measuring device installed inside a box that used to store a liquid. The measuring device is placed at the bottom of the box dispensing the liquid, and displays via a measuring tower a measure of the volume of the liquid still in the box. The device is comprised of a receptacle or sealed pouch connected to a measuring tower. As the pressure from the weight of the liquid changes, the receptacle reacts by moving the measuring marker to reflect such change, thus measuring the current liquid volume in the dispensing box.

The invention concerns a device (1) for measuring a fill level of a flexible medicine reservoir (6). The device (1) comprises a support (2) for supporting the flexible medicine reservoir (6) and a leaf spring member (3). A first section (31) of the leaf spring member (3) is mounted to a fixed bearing. A second section (32) of the leaf spring member (3) is guided by a floating bearing. The leaf spring member (3) is designed for contacting the flexible medicine reservoir (6) and for providing that changes in the fill level of the flexible medicine reservoir (6) effect changes of the form of the leaf spring member (3). A detector (5) is arranged for detecting the effected changes of the form of the leaf spring member (3) and for enabling measuring of the fill level of the flexible medicine reservoir (6).

A system and method for continuous measurement of multiple fluids in multiple tanks and computation of physical properties for each of the multiple fluids continuously, which uses a plurality of probes, at least one client device, a master control processor, and a master control data storage. The system and method can use computer instructions for receiving data from the plurality of probes, receiving data from other detection devices associated with the fluid in each tank, mapping received data to a relational database, and comparing mapped data to stored values associated with prioritized alarm functions. The system and method can also use computer instructions for generating alarms to both a display connected with the master control processor and to at least one client device using a network, generating reports associated with each generated alarm, generating an alarm log, and generating a history of actions taken by a user.

A mica water level gauge glass includes a steam tee fitting, a balance pipe, a water tee fitting, a steam connecting pipe, a water connecting pipe, a condensation tank, a longitudinal vertical gauge body, and a mica assembly. The gauge body includes a thermal compensation cavity, a steam-water cavity, an auxiliary heat confluence device, and a horizontal steam cavity. The exit points of the thermal compensation cavity arranged in the gauge body is lower than the point of the steam-water cavity exiting from the gauge body.

A wireless pressure sensor for sensing pressure of a liquid in a tank includes a hermetically sealed housing, at least one sensor, at least one photocell array, at least one communication device, and at least one energy storage device. At least a portion of the hermetically sealed housing has a diaphragm. The at least one sensor within the hermetically sealed housing is configured to sense the pressure of the liquid. The at least one photocell array is configured to receive light and generate power from the light. The at least one communication device is configured to transmit data corresponding to the sensed pressure using wireless radio frequency signals. The at least one energy storage device is configured to store power generated by the at least one photocell array and provide power to the at least one sensor and the at least one communication device.

A system includes an optical pressure sensor. A controller is operatively connected to receive input from the optical pressure sensor. An output connection is operatively connected to communicate output data from the controller. The controller includes machine readable instructions configured to cause the controller to receive data from an optical pressure sensor, detect an accumulation of contaminant on the optical pressure sensor, and initiate a corrective action through the output connection in response to detecting the accumulation of contaminant.
