Service water is treated water that is used for specific industrial purposes. In the power generation industry, service water is utilized for general plant services. These include pump and instrument seal water, fire water, demineralization, cooling and make-up water supply.
This treated water is stored in tanks around the facility. In the event the supply of water is interrupted, storage tanks with a capacity to support three days to one week of operation allow continued plant operations. Water level in these tanks must be monitored to ensure there is always an adequate supply.
Magnetrol® has produced an applications brochure for the power and utilities industry, detailing measurement challenges and solutions for each step of the power generation process. This blog post is part of an occasional series exploring each application in detail.
Level Measurement Challenges and Considerations
Level measurement and flow detection devices are crucial for effective water source management. Since the treated water is often used for essential services such as cooling and fire prevention, low water level could lead to accidents or explosions. Collectors and storage tanks are typically fixed roof, vertical cylindrical steel tanks, and typical measurement ranges are from 24 to 50 feet. The instruments selected must provide accurate readings in these tank conditions.
