Panel meters are an indispensable piece of equipment appearing in many automated systems. These meters are specially designed to measure, monitor, and display the parameters associated with a specific system. Panel meters can be used as both stand-alone devices or components that are electronically connected to a larger digital instrument panel. Depending on the application, different types of meters have different functions and operating principles.

While the display and installation module of each panel meter may differ, their core operating principles remain the same. Generally speaking, most panel meters use a sensing element to convert an electrical input signal into a visible output. This conversion can take place on a variety of scales, such as voltage, current, impedance, frequency, temperature, power, or load. The measuring instrument then displays a numerical value or an indicator light to show the reading.

Panel meters are available in a variety of sizes, depending on their application. Some popular types of meters include counter meters, hour meters, and frequency meters. Counter meters are used to measure and record total elapsed time or number of counts. They can be used in a variety of applications, including writing down time in the form of seconds, hours, or days. Hour meters are used for measuring the total running time of a system or machine. As its name suggests, hour meters are designed to measure the total running time in hours.

Frequency meters are devices which are used to measure, monitor, and control the frequency of an alternating current. Frequency meters display information regarding frequency in hertz (Hz). They are commonly used in AC power control systems, industrial manufacturing, and maintenance systems, as well as in medical devices.

In conclusion, panel meters are an essential tool for monitoring various parameters associated with a system. These meters use a sensing element to convert an electrical input signal into a visible measurement in voltage, current, impedance, frequency, temperature, power, or load. Depending on the application, different types of meters are available, including counter meters, hour meters, and frequency meters. By using panel meters, engineers can easily monitor various system metrics with a single device.
