Q

Differential pressures can be measured with the use of a __________.

🔍 Key Concepts

• differential pressure vs. absolute or gauge pressure • How each device (diaphragm gage, pressure transducer, manometer) can compare two pressure sources • Typical instrumentation used to measure the difference between two pressures in piping or tanks

💭 Think About

• For each device listed, ask: can this be connected to two different pressure points so it directly indicates the difference? • Think about where you’ve seen differential pressure used on board (filters/strainers, flow measurements, tank levels) and which instrument is commonly installed there. • Consider whether any of these instruments are limited to measuring pressure at just one point referenced to atmosphere.

✅ Before You Answer

• Verify which instruments are specifically designed or can be configured to read P1 − P2 directly. • Check if a manometer can be arranged so that each leg is exposed to a different pressure source. • Confirm whether a diaphragm type gage or pressure transducer can be built or plumbed as a differential device, not just a single-pressure device.
