Can a metal rotameter with an LCD display still have a pointer?

The working principle of the liquid crystal display metal rotor flowmeter is to use electrical signals and mechanical systems to measure the flow of fluids. Its main components include sensors and displays. The sensor is responsible for receiving the signal from the fluid and converting it into an electrical signal, while the display is responsible for converting the electrical signal into numbers or other forms of information on the LCD screen so that the user can intuitively understand the flow of the fluid.

With the development of science and technology, the display mode of instruments has also changed to liquid crystal display, further replacing the traditional mechanical pointer.

As far as the question of whether the metal rotor flowmeter with liquid crystal display can be equipped with a pointer, in fact, this kind of flowmeter can be equipped with a pointer. The pointer is a mechanical device that can present flow information to the user in a more intuitive form. It is not complicated to add a pointer to the metal rotameter with LCD display. You only need to add a pointer indicator on the display. This pointer indicator can be linked to the digital information on the LCD screen, allowing users to obtain both digital and pointer flow information at the same time.

The main advantage of the metal rotameter with liquid crystal display and pointer is that it can provide more intuitive and three-dimensional flow information. For some users who are accustomed to reading pointer meters, liquid crystal display metal rotor flowmeters equipped with pointers will make them feel more familiar and convenient. In addition, the liquid crystal display metal rotameter equipped with a pointer can also provide additional information in some special circumstances. For example, when the LCD screen fails, the user can still roughly judge the flow rate of the fluid by observing the pointer. Traditional metal rotameter flowmeters are equipped with mechanical pointer indicators, so many metal rotameter flowmeters with liquid crystal displays still retain mechanical pointers on the interface.
