(a) A digital mass flowmeter gives a measurement output between 0 and 20.00 kg/min. What are the range and the resolution of the flowmeter, respectively? [2 marks] (b) Explain in your own words the common sources of measurement uncertainty in relation to an instrument. Give an example to illustrate that measurement uncertainty can have a significant impact on our daily lives or industry. [5 marks] (c) A displacement sensor has an input range of 0 to 8 mm, which has been calibrated and the results are shown in Table 1.1 (assume that, apart from non-linearity error, all other errors are negligible). Displacement 0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 (mm) Output voltage 0.0 8.2 15.7 24.5 33.1 39.3 48.2 55.1 64.0 (mV) Table 1.1 (i) Calculate the sensitivity of the sensor. (ii) Estimate the non-linearity of the sensor. (iii) Outline the key issues to be considered if the sensor is calibrated at a local BCS (British Calibration Services) Centre. [8 marks]
