This book presents a rational procedure for flowmeter selection that is based on factual information and will help the professional evaluate the appropriate criteria to arrive at proper flowmeter selection. Introduction The amount of a substance (liquid or gas), passing per unit time through a cross-section is called a flow rate. At the same time, the optical method uses theodolite or total station. Excessive stock variations is often linked to product theft and sabotage, though this may be true in some instances, but at times, this variations may be as a result of inaccuracies in tank calibration. In further research, a prototype can be developed that can accelerate the calibration process using the strapping method (for example, a vertical track measuring robot) or a low-cost prototype theodolite. �� C�� q" �� All rights reserved.
