Other flow meters
Liquidometer mainly measures the liquid level based on a variety of physical principles. Common ones include the buoyancy principle, such as the float-type liquidometer. The float floats up and down with the rise and fall of the liquid level, and the position of the float is converted into a signal of the liquid level through a mechanical structure or sensor. There are also liquidometers based on the static pressure principle. According to the relationship that the static pressure at the bottom of the liquid is proportional to the liquid level, the static pressure is measured by a pressure sensor to obtain the liquid level. In addition, there are liquidometers based on ultrasonic and radar principles. They emit wave signals, and the waves are reflected back after encountering the liquid surface. The liquid level is calculated based on the propagation time of the waves.
