A flow meter sensor is connected to the microcontroller card to convert the signal and display it as a volume flow rate (L/min.) on the data show screen. Standard volume (graduated cylinder) with stopwatch were employed to calibrate the assemble system, and the calibration results were tabulated as following: Measuri L/min. 51 52 54.5 57 68 ng value Real L/min. 53 55 57 64 71 76 77 0 73 74 80 value Determine: 1- Absolute relative error (ARE). 2- Mean value, deviation (error) value and standard deviation (σ). 3- Draw the calibration curve.

The potentiometer was initially invented to measure linear displacement of moving objects. Decades later, engineers invented LVDT to do the same task. What is the main advantage of LVDT over conventional potentiometer? Paragraph V B I Lato (Recom... く 19px... KY

b) A linear variable displacement transducer (LVDT) senses displacement and indicates a voltage output, which is linear to the input. Figure 1 shows an LVDT setup used for static calibration. It uses a micrometre to apply the known displacement and a voltmeter for the output. i) Suggest the independent, dependent and extraneous variables in this calibration. ii) Indicate the basic functional elements of the device in Figure 1 in the form of block diagram. 10 Micrometer Fixed mounts Connector Excitation voltage in Figure 1 Primary coil xx_w_ LVDT E Output voltage 10.135 Voltmeter Secondary coil Core

Question 4 A first order instrument with a time constant of 2 seconds is to be used to measure a periodic input. If a dynamic error of ±2% can be tolerated, 1- determine the maximum frequency of periodic input that can be measured. 2- What is the associated time lag (in seconds) at that frequency?
