Transmitting 1.__-the difference between two related pressure measurements usually used in measurements of pressure, temperature, level, and flow. 2.__-continuous signal that changes to mirror the actual process variable. 3.__-powered by a gas. 4.__use of a logical technique to perform an analysis, in instrumentation, a measurement of a physical or chemical property. 5.__-the series of instruments that work together to monitor and control a single process variable. 6.__a position of height or depth along a vertical axis; in the process industries, level usually means the height of the surface of a material compared to a zero reference point. 7.__keeping a variable at a specific quantity. 8.__ a transmission method that employs discrete electrical signals as opposed to continuous signals or wows. 9.__powered by electricity. 10 .__the movement of fluids, p. 7. 11.__the specific amount of fluid moving past a given point per unit of time. 12.__-the showing of a current process variable condition via a readout(eg, digital or analog). 13.__related to instrumentation in close physical proximity to the process, generally found outside the control room 14.__communicating via electronic or pneumatic signal from one control loop component to another. 15.__-the amount of force a substance or object exerts over a specific area. 16.__measurements of the chemical or physical properties of a process stream, generally relating to operating parameters or product 17.__Tuning parameters utilized in a controller to ensure appropriate response to process variable changes in comparison to set point. 18.__the keeping of historical data by making a documented record. 19.__relating to instrumentation located away from the process (e.g., in a control room) and controlled by the distributed control system (DCS) or other panel board mounted controller. 20.__-the measure of the thermal energy of a substance. 21.__-the quantity of fluid moving past a given point per day (e.g., 4 GPM X 60 min hr X 24 hr 240 X 24 5760 gal/day), p.7.
