Working principle

The pressure sensor probe is placed in the measured liquid and subjected to a certain static pressure of the medium (P). This pressure is proportional to the liquid being measured

The height (h, m) is proportional to P=ρ gh (Pa), where ρ is the specific gravity of the medium (g/cm ³) and g is the local gravity plus

Speed (m/s ²), for the measured medium and location, ρ and g are constants. The electronic components of the transmitter measure the liquid level pressure measured by the pressure sensor

The force signal is transmitted to the display instrument, and the liquid level signal of the medium is displayed through circuit conversion.
