Abstract
A tool sensor calibration system and tool calibration method are disclosed herein. A tool sensor calibration system (200) comprises a flow pipe (206), an isolation cell (214) in fluid communication with the flow pipe, a sensor (210) positioned proximate to the isolation cell, a fluid chamber (213) containing a reference fluid (212) with a known property value, and a first valve (222a) coupled to the fluid chamber that provides selective fluid communication between the fluid chamber and the flow pipe. A tool calibration method comprises introducing a first fluid (208) into a flow pipe, introducing a reference fluid into the flow pipe from a fluid chamber in fluid communication with the flow pipe through a valve, wherein the first fluid and the reference fluid mix to form a composite fluid, and detecting a property of the composite fluid at an isolation cell in fluid communication with the flow pipe.
