Abstract
A flow metering apparatus comprising a temperature sensing system for use to measure temperature of fluid includes temperature measurement components and temperature sensing components in close proximity to one another and to the flow of fluid. The components can include a temperature measurement member close-coupled to a processor member, each disposed on a circuitized substrate. This configuration exposes a temperature sensor element to the same dynamic temperature conditions as the processor member, thus reducing measurement error that might manifest in response to different temperature gradients proximate the respective components. A storage memory may be used to permit the temperature sensing system to store and/or retain data that relates to calibration as a dynamic system over the entire operating range of the sensor element. The calibration data may then be accessed from the storage memory to improve accuracy and operation of the flow metering apparatus.
