The product consists of a high-performance pressure sensor as the measuring element, by the pressure sensor, and the level of the hydrostatic pressure proportional to the depth of accurately measured, and through the dedicated signal conditioning circuit is converted into a standard (current or voltage) signal output, establish output signal with a linear correspondence between the liquid depth, accurate measurement of the liquid depth. Products of high precision, small size, easy to use, directly into the liquid, you can measure the transmitter end to the surface of the liquid level. For petroleum, chemical, power plants, urban water supply, the water level in the field of hydrology exploration or level measurement and control.
