Abstract: Ultra-high accuracy elevation and pressure telemetry devices are used to develop an autonomous, self-calibrating hydraulic piping network computer simulation model. Virtual pressure reducing valve (PRV) model elements force a local downstream calibration of the model using the pressure telemetry data, overcoming the potential ill conditioned state when simulating wide ranging, real world operational conditions. This technique also creates a smaller solution set for calibration optimization algorithms such as machine learning. Additional benefits of this technique include the ability to ignore complex facilities such as pump stations, water storage tanks, and control valves enabling a more rapid development of the real-time water piping network computer simulation model.

Abstract: A remote hydraulic and water quality monitoring and telemetry device for being connected to a fire hydrant. The device connects to a hydrant nozzle via a swivel connection and includes a control valve mounted inside the nozzle to conserve space and release a determined volume of water from the hydrant lateral pipe to provide a sample from the main line pipe. The device includes a multi-parameter water quality sonde or sensors, data acquisition, and telemetry hardware. The door of the enclosure may include a solar panel. The device may rest on a plate mounted to the hydrant riser flange after the hydrant and upper hydrant valve stem are removed. The device may rest on the ground and be connected to a hydrant nozzle by a rotating pipe assembly which can be adjusted to be positioned at locations around the hydrant and at varying elevations relative to the hydrant nozzle.
