Monitoring backpressure in pressure relief systems is essential primarily to ensure safety and the proper operation of the relief device. Backpressure refers to the pressure upstream of the relief device, which can significantly influence how and when the device activates. If backpressure is too high, it might prevent the relief valve from opening when needed, thereby failing to release excess pressure and potentially leading to catastrophic system failures, explosions, or other dangerous situations.

Moreover, the correct operation of the relief device is vital for maintaining the integrity of the system and ensuring that it can perform its intended safety functions under various operating conditions. Regular monitoring helps to identify any abnormalities or changes in pressure that could compromise safety measures, enabling maintenance or adjustments to be made proactively. This practice is a critical component of risk management in systems that involve pressurized fluids or gases.
