*Please check the detection performance of Proximity Sensors with the deviceto be installed before use, as stable detection may not be possible in the following cases.
(1) Proximity Sensors, If the liquid has a low dielectric constantor conductivity, the device may not be able to detect the liquid level because it is a capacitance type.
(2) Proximity Sensors, If the liquid volume is small, or the pipesize is thin and thick, resulting in a small change in capacitance in response to a change in the liquid level.
(3) Proximity Sensors, If there is a high-viscosity liquid film or a large amount of bubbles remainingon the inner wall of the pipe, or if dirt has adhered or accumulated on the inner and outer walls of the pipe.
