devices require accurate pressure and temperature measurement in order to calculate the output of the instrument. Flow rate is express in Volume units (m³/s) and Mass units (kg/sec). The fluid can be corrosive, clean or dirty, single phase or multiple phase, laminar or turbulent. Hence, there are two types of devices, primary device (quantity meters) and secondary devices (rate meters). In this experiment, we will learn different types of flow meters devices to measure liquid (water) volume flow rate. The flow meters used on the apparatus are venturi
Theory and Design for Mechanical Measurements
Measurement is a term that refers to analyzing a manufactured component regarding the degree of accuracy for dimensions, tolerances, geometric profile, roundness, flatness, smoothness, etc. Measurement always involves comparing the manufactured component or the prototype with a standard specimen whose dimensions and other parameters are assumed to be perfect and do not undergo changes with respect to time.Precisely in mechanical engineering the branch that deals with the application of scientific principles for measurements is known as metrology. The domain of metrology in general deals with various measurements like mechanical, chemical, thermodynamic, physical, and biological measurements. In mechanical engineering, the measurements are limited to mechanical specific such as length, mass, surface profile, flatness, roundness, viscosity, heat transfer, etc.
Basic principles of engineering metrology
Metrology is described as the science of measurement, precision, and accuracy. In other words, it is a method of measurement based on units and predefined standards.
