Water gauges come in a variety of types, including mechanical, digital, and electronic models. Mechanical water gauges are the simplest and most traditional type, and they use a float to indicate the water level.

The installation of a water gauge will vary depending on the type of gauge that you choose. However, most water gauges are installed by connecting them to a pipe or tank with a threaded fitting.
