摘要： A system for measuring the velocity of a fluid can comprise a temperature sensor, for measuring the ambient temperature of the fluid, an RTD placed in the flow path of a fluid, the RTD being included as part of a Wheatstone bridge circuit, a digital potentiometer, the digital potentiometer also being included as part of a Wheatstone bridge circuit, and a controller coupled to the temperature sensor, the RTD and the digital potentiometer. In the system, the controller adjusts the digital potentiometer in response to an ambient fluid temperature signal from the temperature sensor such that the temperature of the RTD remains at a constant differential temperature above the ambient fluid temperature.

摘要： The present invention is directed to monitoring/alert systems, devices, and methods useable with animal housing units. Embodiments include a primary component, such as a system controller device, for monitoring maintenance and operational events in a housing unit and a secondary component, such as a environmental monitoring device for analyzing environmental conditions. For example, the system controller device monitors unit functions (e.g., relating to power, pre-filter(s), filter(s), fan(s), air pressure, air temperature, electrical connections, etc.) and causes alert(s) to be sent (e.g., via email or text message) if there is a malfunction or abnormal operational data. The environmental monitoring device collects environmental data (e.g., time, temperature, humidity, light, sound, carbon dioxide levels, or ammonia levels) and causes alert(s) to be sent if an abnormal environmental condition is detected. The primary and secondary components may function in connection with one another, other devices, a network, or as stand-alone devices.
