Differential pressure gauge ( Ashcroft ) In many applications fluids passing through a pipe require filtering this results in the need for continuous differential pressure monitoring. Differential pressure gauges, switches and transmitters help monitor your processes. Filters and strainers commonly are positioned to capture solids and particulates. The filter will obstruct the flow through the pipe lowering the pressure on the downstream side. These effects may vary depending on the filters construction. Filter media is the material that removes impurities. The smaller the pores, the larger the friction. Higher friction means greater pressure drop. Contaminants or particulates that build up in the filter will reduce media flow. As the filter becomes clogged, the downstream pressure drops. This results in an increased differential pressure, also referred to as the Delta-P. Saturated filters may also begin to shed captured particles. With the filter no longer functioning properly,

The pressure relief valve is used to control or limit the buildup of pressure in a piping system, tank or vessel. When process pressure is exceeded, a pressure relief valve becomes the “weak link” and the valve opens to divert a portion of the fluid to another path. The diverted liquid, gas or liquid is usually re-routed through a piping system to a process where it is safely contained or burned off via a flaring system. Once the liquid or gas is diverted, the pressure inside the vessel drops below the safety relief valves' re-seating pressure, and the valve closes. The video below provides an excellent understanding of how pressure relief valves operate and the difference between direct acting and pilot operated pressure relief valves.
