Abstract: A discrete valve flow rate converter is provided to obtain a system flow through a valve in a dynamic hydronic pumping system, e.g., based on signaling containing information about the valve's differential pressure and the valve's hydronic characteristics calibration data. The discrete valve flow rate converter resolves the valve system flow rate directly and accurately with the valve's open position and the corresponding valve differential pressure signals associated therewith. The discrete valve flow rate converter may be applied to all kinds of valves as long as their open position and differential pressure associated with is available, e.g., including implementations for control valve applications, e.g., where the valve open position is controlled automatically and accurately, as well as implementations either for pumping system pressure controls with the flow rate known, such as adaptive hydronic system pressure controls, or as an alternative to sensorless pump monitoring and control.

Abstract: A condition monitoring device for monitoring machinery includes a combination of on-board sensors and a condition monitoring module. The on-board sensors include modules for non-contact temperature, magnetic flux and 3-axis vibration sensing of the machinery. The condition monitoring module provides a condition monitoring signal containing information about an operating condition of the machinery, based upon a data synthesis condition monitoring technique that synthesizes non-contact temperature, magnetic flux and 3-axis vibration sensed data received from the combination of on-board sensors, determines a current operating condition of the machinery, and compares the current operating condition and the baseline operating condition of the machinery.
