Measuring principle
The submersible level transmitter operates based on the principle that the static pressure of a liquid is proportional to its height.
Using the piezoresistive effect of a diffused silicon pressure sensor, the hydrostatic pressure generated by the liquid column is converted into an electrical signal. After temperature compensation and linear correction, the signal is transformed into standard 4–20 mA, voltage, or RS485 output, enabling accurate and stable liquid level measurement.
