Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.
The Pressure for Safety in Gas Stations
For safe fuel storage and delivery, frequent maintenance and monitoring of the equipment in gasoline stations is certainly advised and may be required by federal and/or local legislation. In addition to the hazards presented by leaks, they are also costly to the service station operation. In all instances, to prevent or detect problems, pressure measurements are essential.
For example, static pressure testing for fuel lines and gas stations requires a pressure gauge to ensure that everything is working properly and not leaking. Test equipment to verify this performance can range from sophisticated and expensive to straightforward and cheap.

Stage II Vapor Recovery Control
For many years, Stage II Vapor Recovery Control in gas stations (aka gasoline dispensing facilities or GDFs) was required by many regions in the U.S. To quantify the vapor tightness of vapor recovery systems installed at GDFs equipped with pressure/vacuum (P/V) valves, the designed pressure setting of the P/V valves has to be a minimum of 2.5 inches of water column (inches H2O) to verify the 2-inch water closet (WC) static pressure performance of the system.
However, since the early 2000s, many vehicles have been equipped with onboard refueling vapor recovery (ORVR) systems. These ORVR controls have essentially eliminated the need for Stage II vapor recovery systems in service stations.
