In the second half of the 19th century, mechanical engineering became an independent discipline. In the 20th century, with the development of mechanical engineering technology and the growth of total knowledge, mechanical engineering began to decompose, and specialized branch disciplines appeared one after another. The decomposition trend reached its peak in the mid-20th century (before and after the end of the Second World War). Since the total amount of knowledge in mechanical engineering has been extended to far beyond the mastery of a single person, certain specialization is essential. However, excessive specialization leads to excessive division of knowledge and narrow vision. It is impossible to supervise and coordinate the overall picture and overall situation of a relatively large-scale project, and to narrow the scope of technical exchanges, hinder the emergence of new technologies and the overall progress of technology, and change external conditions ( Such as the emergence of new technologies, new materials and new products, supply of materials and semi-finished products and price changes, etc., the ability to adapt is very poor. Experts in closed professional disciplines have too narrow knowledge to consider problems, and they have difficulties in coordinating coordination when working together, which is not conducive to continuing self-study. Therefore, from the middle and late 20th century, mechanical engineering has shown a comprehensive trend. People pay more attention to basic theories, broaden their professional fields, and merge their specialized professions.
The steel ruler water level meter is the most accurate way to measure the water level. A metric or imperial scaled steel ruler attached to a probe that is mounted on a metal or plastic steel. It is usually used to measure the water level in wells, boreholes and water level pipes. It is especially suitable for the observation of groundwater level in hydropower projects or the manual inspection of dam body immersion lines of earth and rock dams. The devices are characterized by a simple, fast and reliable measurement acquisition.
