A digital water flowmeter is a device used to measure the flow rate of water. It is typically used in water distribution, wastewater treatment, and irrigation systems. The digital water flowmeter uses a turbine wheel or paddle wheel to measure the rate of water flow. This wheel is connected to an electronic circuit, which converts the rotational speed of the wheel into a digital signal that is read and displayed on an LCD display. The digital display allows the user to accurately measure the rate of water flow in terms of gallons per minute (GPM) or liters per minute (LPM).
