What is the BAK-12 hydraulic pressure gauge used for?

The BAK-12 hydraulic pressure gauge is specifically used for hydrostatic testing. This type of gauge is designed to measure the pressure of a fluid in a system, typically in applications where the integrity and strength of pipes, tanks, and other pressure vessels are tested. During hydrostatic testing, a vessel is filled with water and pressurized to a predetermined level to check for leaks and structural weaknesses. The BAK-12 provides accurate pressure readings vital for ensuring that the tested system can safely withstand the operational pressures it will encounter.

The other options do not pertain to the primary function of the BAK-12. For example, pressure relief refers to devices that release pressure to prevent over-pressurization, which is a different application than what the BAK-12 is designed for. Fluid temperature monitoring involves sensors and gauges that measure temperature, not pressure. Lastly, flow rate measurement requires different equipment, such as flowmeters, which assess the volume of fluid passing through a system rather than the pressure within it. Therefore, hydrostatic testing aligns perfectly with the intended use of the BAK-12 hydraulic pressure gauge.
