What device can be used to calibrate a pump?

1. Spirometer

2. Calibrometer

3. Manometer

4. Rotameter

The correct answer is: Rotameter

The correct answer is a rotameter, which is an instrument used to measure the flow rate of liquids and gases. It operates on the principle of variable area flow measurement, where the flow rate is indicated by the position of a float within a tapered tube. In the context of calibrating a pump, a rotameter can provide a precise measurement of how much fluid the pump is moving, allowing for adjustments to ensure accurate flow rates. Using a rotameter for calibration is advantageous because it provides real-time feedback on the flow rate, enabling technicians to make necessary modifications to the pump's settings to achieve optimal performance. The visibility of the float's position makes it easy to monitor changes, which is crucial during the calibration process. This capability allows for accurate assessment and ensures that the pump operates within the desired parameters, promoting efficiency and reliability in applications that rely on specific flow rates. The other options, such as a spirometer, calibrometer, and manometer, serve different functions. A spirometer is primarily used to measure respiratory volumes, a calibrometer measures the accuracy of measuring instruments, and a manometer measures pressure rather than flow rate. Each of these instruments has a specific application, which makes them less suitable for calibrating a pump compared to
