What is the primary function of the vacuum gauge in a metering pump installation?

The primary function of a vacuum gauge in a metering pump installation is to indicate vacuum levels. This is crucial because metering pumps often operate in conditions where maintaining a specific vacuum is essential for optimal performance. The vacuum gauge measures the negative pressure within the system, providing important feedback about the operation of the pump and related components.

This information helps ensure that the pump is functioning correctly and that the system is sealed properly to prevent any air leaks, which can affect flow rates and the accuracy of fluid delivery. Being aware of the vacuum levels allows operators to adjust the system as necessary to maintain efficiency and prevent issues such as cavitation or pump malfunction.

In contrast, measuring fluid flow rate, gauging pressure difference, and monitoring temperature are roles typically fulfilled by different instruments specifically designed for those purposes, rather than by a vacuum gauge.
