What is the role of the high flow alarm in a meter based timing system?

The high flow alarm in a meter-based timing system serves a critical safety function by diverting the flow when the rate exceeds a preset level. This is particularly important in pasteurization processes, where maintaining a consistent flow rate is vital for ensuring that the product is adequately heated to eliminate harmful pathogens. If the flow rate surpasses the designated threshold, it could indicate a malfunction or an unsafe condition that could compromise the quality and safety of the product.

By diverting the flow in such instances, the system protects both the equipment and the product, ensuring that the pasteurization process remains within its operational parameters. This proactive measure helps prevent potential hazards and maintains compliance with safety standards, thereby safeguarding public health. The other options do not accurately describe the function of the high flow alarm in the context of a meter-based timing system.
