Resistance Temperature RTD: A sensor whose resistance changes proportionally to
Detector detector temperature changes.
Span An adjustment that establishes at what flow rate the
flow transmitter's output is full scale.
(Also, the difference between the upper and lower flow rate values.
Thermal flowmeter An instrument that uses thermal technology to measure fluid flow rate.
Thermowell The flow element part that protects the heater and RTDs from the process fluid.
Turn down The ratio of the upper to lower flow rate values.
Zero An adjustment that establishes at what flow rate the flow transmitter's
output is zero.
