Which gauge type yields a digital readout and is commonly used where data integration and automation are important?

• A. Analog gauge
• B. Mercury gauge
• C. Digital gauge
• D. Dial gauge

Answer: (C)

The gauge type that yields a digital readout is the one designed to display measurements numerically and to interface with electronic systems. A digital gauge directly shows the measured value as numbers and typically provides electronic outputs or communication capabilities, making it easy to send data to SCADA, PLCs, or data historians. This seamless data transfer supports automation, real-time monitoring, trending, and alerts, which are essential in modern water distribution operations. In contrast, gauges that rely on a dial or needle (analog, dial) require manual interpretation and don’t readily feed into automated systems. Mercury gauges are older, use hazardous liquid, and are not geared toward digital data integration. So the digital gauge is best when precise numeric readings and smooth integration with data and automation are needed.
