Combining several capillary tubes in one depth gauge, which measure the depth in different ranges, will allow obtaining a measuring scale close to linear and eliminate the main disadvantage of a capillary depth gauge.

A frozen food product dispensing machine includes a housing, a freezer barrel disposed within the housing, a plurality of drawers, and a manifold comprising a plurality of inlets and one outlet. The plurality of drawers are disposed within and slidably coupled to the housing and configured to each support a liquid food product mix reservoir. The inlets are each fluidly coupled to one of the liquid food product mix reservoirs, and the outlet is fluidly coupled to the freezer barrel to supply liquid food product mix from all of the liquid food product mix reservoirs to the freezer barrel.

A pneumatic probe includes a port adaptor and a pneumatic core. The port adaptor includes an insertion head that includes a hook, and a backstop alongside the insertion head behind, and in spaced opposition with, the hook. The insertion head is reconfigurable between an expanded configuration and a contracted configuration. The backstop is movable, along the insertion head, between an extended position and a retracted position, in which the backstop is respectively advanced toward the hook and backed away from the hook. The pneumatic core includes a downtube extending through the insertion head, and a blocker on the downtube interfaced with the insertion head. The downtube is movable, through the insertion head, between a blocking position and an unblocking position with respect to the insertion head.

A method for determining the phase interface level of a multiphase system, includes a tank intended to receive a multiphase system including at least two fluids having distinct phases, and a tube vertically immersed inside the tank. The tube is intended to be filled with a fluid at equal pressure with the fluid contained in the tank at the level of a headspace of the tank. The tube has a plurality of differential pressure sensors per membrane which are spaced apart vertically from each other along the tube to measure the pressure difference between the fluids contained and stratified in height in the tank and the fluid contained in the tube.

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 sensor assembly comprises a housing, a pressure interface, a piezoelectric sensor, a mechanical interface, and an electrical interface. The pressure interface is disposed on the housing and communicates with a pressure transmission tube. The piezoelectric sensor is disposed in the housing and senses a pressure input at the pressure interface. The mechanical interface is disposed at a first side of the housing and detachably engages a mounting mechanism. The electrical interface is disposed at a second side of the housing opposite to the first side.

Apparatuses for measuring a fluid, each apparatus including a (e.g., butterfly) valve in communication with the fluid and a (e.g., pressure) transducer that measures (e.g., volume of) the fluid, where the transducer is mounted on the valve. A valve for controlling a fluid, the valve having a transducer mounted on the valve. An apparatus for storing and measuring liquid, for instance, milk, the apparatus including a tank that holds the liquid or milk, a valve connected to the tank that controls flow from the tank, and a pressure transducer mounted on the valve, where the pressure transducer measures pressure of the liquid or milk in the tank; and the pressure in the tank is used to calculate quantity of the liquid or milk in the tank. The transducer may be mounted at, or parallel or concentric to, the axis of rotation of the valve, and the axis may be vertical. The transducer may be mounted on the bottom of the valve.
