Non-invasive Describes system or procedure that does not involve the entry into or – penetration of the subject studied for the collection of data. PVC (Polyvinyl Chloride) A type of plastic pipework which is used for the – conveyance of drinking water, waste water, chemicals, heating fluid and cooling fluids, foodstuffs, ultra-pure liquids, slurries, gases, compressed air and vacuum system applications. PZT (Pb[Zr(x)Ti(1-x)]O3) Lead Zirconate Titanate; a ceramic perovskite material – that shows a marked piezoelectric effect, which find practical applications in the area of electroceramics. Reynolds Number In fluid mechanics, the Reynolds number (Re) is a dimensionless – number that gives a measure of the ratio of inertial forces (which characterize how much a particular fluid resists any change in motion, not to be confused with inertial forces defined in the classical way) to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditions. RTDs (Resistance Temperature Detectors) These are sensors used to measure – temperature by correlating the resistance of the RTD element with temperature. Teflon® name of Polytetrafluoroethylene (PTFE) by DuPont Co. PTFE is – a solid, as it is a high- compound consisting wholly of and . PTFE is : neither water nor water-containing substances wet it. PTFE has one of the lowest coefficients of against any solid. (FEP and PFA are also commonly referred to as “Teflon”. Totalizer A device or meter that continuously measures and calculates (adds) total – accumulated flow. Transducer A device that converts variations in a physical quantity, such as pressure – or brightness, into an electrical signal, or vice versa. Transit Time (Time of flight) Length of time elapsed between departure and arrival – of an ultrasonic signal from one transducer to the other. Transmitter A set of electronic equipment used to transmit messages or signals. – Ultem® Brand name of Polyetherimide (PEI) by SABIC. PEI is an amorphous – thermoplastic with properties of heat resistance, solvent resistance and flame resistance.
