One example may be before and after a valve in a pipe. If the valve is fully open, the pressure on both sides should be the same. If there's a difference in the pressure, it could be the valve isn't fully open or there's a blockage. Differential Pressure Sensor

I’m so impressed with these chunky earrings. It’s hard for me to find earrings that aren’t too big or too small for my face shape. These are just perfect. A little more expensive than I usually spend for earrings- but these replace about 10 other cheap pairs… Lesson: buy what you really love!
