An instrumented coupling for pipe joints is described herein. The instrumented coupling includes a first threaded end configured to thread to a first pipe joint and a second threaded end configured to thread to a second pipe joint. The instrumented coupling also includes a sensor configured to obtain a measurement of a parameter of a well and a communications device configured to communicate to a receiving device outside of the well. The instrumented coupling further includes a processor configured to execute instructions in a data store. The instructions direct the processor to read the measurement from the sensor, compare the measurement from the sensor to a preset limit, and generate a signal within the communications device based, at least in part, on the measurement.

Systems and methods for material composition detection includes a vessel containing a quantity of a fluid composition therein which has at least a first and second fluids. At least one acoustic transducer is positioned on an exterior sidewall of the vessel. A computerized device has a processor and is in communication with the acoustic transducer.
