DAY2- PROCESS VARIABLES Flashcards
Density of air at STP
1.2929 g/L
A type of monitory device where a buoyant member is attached to a resistor or magnet that sends signal to the gauge
Float Actuated device
This monitoring device uses the concept of thermal expansion of liquids
Thermometer
EMF is produced if two wire ends are in different temperatures. The EMF is detected as signal then read digitally. What device is this?
Thermocouple
A non-contact instrument that uses the concept of electromagnetic radiation to measure temperature
Pyrometer
Pressure exerted by fluid at rest.
Static Pressure
Exerted by the fluid in motion.
Dynamic Pressure
This device measures fluid column height and converts it to pressure
Manometer
Consists of a vertical tube with a tapered bore in which a float changes postion with the flowrate through the tube
Rotameter
Examples of Chromatographic analyzers
Gas chromatography, high performance liquid Chromatography(HPLC)
Measures temperature through electrical resistance of a conductor
resistance thermometer
