IoT liquid level sensor with high precision and stability, fast transmission

The cable type liquid level transmitter uses a high-energy diffusion piezoresistive pressure transmitter as the measuring element to accurately measure the hydrostatic pressure proportional to the depth of the liquid level, and convert it into a standard (current (Or voltage) signal output to establish a linear corresponding relationship between the output signal and the liquid depth to realize the measurement of the liquid depth. The internal dedicated integrated circuit converts the sensor's millivolt signal into a standard long-distance transmission current signal, which can be directly connected to the computer interface card control instrument, smart instrument or household LC. The product has high precision and small size. It can be directly put into the liquid to measure the height of the liquid from the end of the transmitter to the liquid surface, which is easy to use.

is suitable for liquid level measurement and control in the fields of petroleum, chemical industry, power plants, urban water supply, and hydrological exploration.

[Smiles said this inadvertently, books introduce us into the most beautiful society, and let us know the great wise men of all ages. This sentence brings us to a new dimension to think about this problem: when the problem occurs, how do we need to do it, and how will it happen if the problem does not occur. Spinoza said inadvertently that the greatest pride and the greatest low self-esteem all mean the weakest soul. This sentence brings us to a new dimension to think about this problem: I think, then, why does the problem occur? The so-called problem, the key is how to write the problem. Under such a difficult choice, I want to go, and I have trouble sleeping and eating]
