Claim Text:
1. A probe with no moving parts for use in a tank, the tank having a floor and at least one wall, the probe configured for continuous measurement of a fluid while immersed in the fluid, wherein the probe comprises: a) a processor housing; b) a plurality of pressure transducers, each pressure transducer having a diaphragm, each pressure transducer configured for continuous pressure measurement through direct contact with the fluid in the tank; c) a plurality of temperature sensors, each temperature sensor contained in either one of the pressure transducers or in a sensor housing, each temperature sensor configured for continuous temperature measurement of the fluid in the tank; d) a computer processor in the processor housing, the computer processor electrically connected to the plurality of pressure transducers and to the plurality of temperature sensors; and e) a probe data storage in the processor housing, the probe data storage in communication with the computer processor, the probe data storage being a non-transitory computer readable medium containing computer instructions stored thereon for causing the computer processor to control the plurality of temperature sensors and the plurality of pressure transducers to produce bidirectional signals to the plurality of temperature sensors and the plurality of pressure transducers to a network, the probe data storage containing: wherein the computer processor comprises a temperature sensor simulation circuit with a temperature reference value in the probe data storage and a pressure transducer simulation circuit in the computer processor with a pressure reference value in the probe data storage, the temperature sensor simulation circuit and the pressure transducer simulation circuit for calibrating the computer processor for measuring temperature or pressure.
