What type of instrumentation displays information provided by sensors?

Secondary instruments are designed to display or indicate information that has been measured or sensed by primary sensors. In a water distribution system, sensors can gather data such as flow rate, pressure, or temperature. The secondary instruments take this raw data and present it in a readable format, which could be digital readouts, dials, or graphs. This allows operators and technicians to understand system performance and make informed decisions based on the displayed information.

Understanding this distinction is important in water distribution systems, as effective monitoring and reading of sensor data is crucial for ensuring the infrastructure operates efficiently and safely. The other types of instruments mentioned have different roles: primary instruments are responsible for the actual measurement, diagnostic instruments focus on analyzing system health and performance, and control instruments are used to manipulate system operations based on the data received.
