Most flow measurements occur under_______ flow conditions correct answer: Turbulent Full compensation of remote reading thermometer would typically be a provided by a: correct answer: Secondary capillary An increase in the viscosity of a liquid will result in a _______ Reynolds number correct answer: Lower In most process control systems the process measurement is derived by a: correct answer: Sensor When using a voltmeter without reference junction compensation to measure the output of a thermocouple it is necessary to: correct answer: Subtract the reference junction millivolts from the instruments voltage readings A type of level transmitter which may require that the vessel containing the liquid was open to the atmosphere would be a: correct answer: Bubbler A bubbler has the following instruments connected art of the control loop; FI1001, PCV1001, LIT1001, LIC1001. Which device when most commonly be used for the flow indicator? correct answer: Rotameter The most common unit of measurement for liquid pressure or level is: correct answer: Inches of water The temperature at which the moisture in the air will become saturated and begin to deposited as condensation is the correct answer: Dewpoint A type of open channel flow meter which is typically used to measure water flow is the: correct answer: Parshall Flume When checking the collaboration of a differential pressure transmitter you find that it renders readings at the 25% 50% and 75% test points which are substantially higher than anticipated. This would probably indicate that the instrument probably has: correct answer: Square root extraction TE 1002 The symbol shown would most likely represent a: correct answer: Thermocouple Loss of signal from the compensation lead of
