A pressure monitoring system for a wet barrel hydrant includes an outer housing defining a sidewall shell and a cap coupled to the sidewall shell; a sensor housing defining a connector, a housing cavity, and an opening formed through the sensor housing and allowing access to the housing cavity, the connector configured to couple the pressure monitoring system to a wet barrel hydrant; and a base assembly coupled to the sidewall shell and defining a central support and a cylindrical wall, the cylindrical wall extending from the central support towards the cap, the sensor housing coupled to the central support opposite the cylindrical wall.

A manifold assembly configured to measure differential pressure of fluid. The manifold assembly may have a monolithic body with an internally drilled fluid pathway. The body supports a differential pressure transducer that communicates, on either end, with the internally drilled fluid pathway. This configuration can generate data that defines pressure drop across impellers or other mechanisms on metrology hardware (or “gas meters”). Utilities can use this data to diagnose health or other conditions on the gas meter in the field.

Example aspects of a pressure monitoring system for a wet barrel hydrant, a pressure monitoring and leak detection system for a wet barrel hydrant, and a method for using a pressure monitoring and leak detection system are disclosed. The pressure monitoring system for a wet barrel hydrant can comprise a pressure sensor assembly comprising a pressure sensor and a connector, the pressure sensor configured to measure the pressure of a fluid received in the wet barrel hydrant, the connector configured to attach the pressure monitoring system to the wet barrel hydrant; a mounting flange coupled to the pressure sensor assembly; a main PCB configured to process pressure data measured by the pressure sensor; an antenna configured to send a signal representative of the pressure data; and a housing coupled to the mounting flange, the housing enclosing the processor and the antenna.

A sensor attachment structure of an oil pressure sensor suitable for use as a control valve of an automobile transmission includes a sensor case inserted into an accommodation space 4 of a valve upper-body portion such that a body portion of the sensor case is capable of rotating about a vertical central axis. A stopper projects in a horizontal direction from the upper body, the stopper being movable vertically in a guide groove of the sensor case, and a rotatable relative to a restricting portion of the central case to restrict a vertical movement of the stopper to prevent the oil pressure sensor from falling off the upper body.

The invention relates to an arrangement composed of a measuring device and a container, wherein the measuring device (1) is suited for insertion into the container, which contains the medium to be measured, and wherein the container for receiving the measuring device (1) has a connector piece (20) having a passage opening extending in an axial direction and a seal land (22) projecting into the passage opening, wherein the measuring device (1) comprises a rotationally symmetric housing part (10), which is flush with the connector piece (20) and has an external cone portion (11), which forms with an internal cone portion (21) provided on the connector piece (20) a beveled sealing surface pair.
