Abstract
A water pressure sensor assembly includes a water connection fitting attached to a housing, where the water connection fitting is configured to attach to a point of use in a plumbing system. A pressure sensor and an optional temperature sensor are disposed within the housing and configured to be in fluidic communication with the point of use in the plumbing system. Another temperature sensor measures the surrounding air temperature. An electronic microprocessor is disposed within the housing and in electrical communication with the pressure sensor and the temperature sensors. A power source is in electrical communication with the electronic microprocessor. A data transmission path is in electrical communication with the electronic microprocessor. A control device is in electrical communication with the electronic microprocessor through the data transmission path, the control device including a visual display and at least one user control configured to control the water pressure sensor assembly.
