CHAPTER 1INTRODUCTION TO FLOW METERS
COOLING WATER

As mentioned above, "cooling water" is one of the most frequently used applications of water in Factory Automation. Additionally, due to its role in the prevention of overheating during processing, "cutting water", often referred to as coolant, can be broadly classified as "cooling water" as well. Opposite to cooling, water may also be used as "insulating water".

Tap water is not generally used because "cooling water" is not for human consumption. Instead, industrial water is pumped from groundwater or directly from rivers. Because all water is viewed as a limited and vital resource, it is generally circulated repeatedly prior to being cleaned and discharged.

Cooling tower: The upstream section cools and then pumps the water to Factory Automation equipment. The downstream section serves as the return to the cooling tower after flowing through the equipment. Naturally, the water temperature in the downstream section will be warmer than the water in the upstream section. Also, chillers, heaters or thermolators are frequently used in the upstream section.
