1. A method for monitoring a property of a fluid in a fluidic system using a flexural resonator sensor, the method comprising porting a subassembly of a sensor to a first fluidic system, the fluidic system comprising an installed flexural resonator, the ported sensor subassembly comprising a data retrieval circuit or a signal processing circuit, interfacing the ported sensor subassembly with the first fluidic system at a first location to form an interfaced sensor, the interfaced sensor comprising the installed flexural resonator having a sensing surface positioned for contacting the fluid, the signal processing circuit in electrical communication with the flexural resonator, and the data retrieval circuit in electrical communication with the signal processing circuit, sensing the fluid using the interfaced sensor during a first sensing period to generate data associated with one or more properties of the fluid, storing, displaying or transmitting the data using the data retrieval circuit, disinterfacing the ported sensor subassembly from the first location of the first fluidic system after the first sensing period, porting the sensor subassembly away from the first location of the first fluidic system, and subsequently thereafter, porting the sensor subassembly to one or more of (i) a second fluidic system, (ii) a second location of the first fluidic system, or (iii) the first location of the first fluidic system, in each case for interfacing therewith to monitor a property of a fluid during a second sensing period.
