Industrial processes are procedures involving chemical, physical, electrical or mechanical steps to aid in the manufacturing of an item or items, usually carried out on a very large scale. Industrial processes are the key components of heavy industry.Industrial process solution involves monitoring and controlling machinery, systems, and processes across a large number of industries: chemicals, pharmaceutics, biotechnology, energy, water/wastewater, oil, gas, plastic, paper, food, and beverages. Nowadays, industrial preparation, processing, and manufacturing systems are highly automated in order to ensure that raw materials and energy are consumed in a conservative and efficient manner. In this context, the ability to measure pressures, levels, and flow rates reliably and precisely in harsh, humid, and dusty environments and to measure aggressive, corrosive, explosive, and other liquids and gases is essential.
