Product description: Non-contact liquid level sensor - digital - DFRobot SEN0368
Manufactured by the companyDFRobotThe non-contact capacitive liquid level sensor is equipped with astatus indicator and the possibility of adjusting sensitivity. This product can be used to detect liquids in non-metallic containers or pipes(external diameter greater than 11 mm). Feedback on the status of the sensor takes place in real time. In addition, this sensor is equipped with a 4-pin adapter, which allows the direct collection of a digital signal, convenient for connection toArduinoor other microcontrollers. This product features a wide applicability in detecting liquid in a tank, water dispenser, etc. This non-contact liquid level sensor is developed with advanced signal processing technology using high-speed chip. The measurement is not affected by the thickness of the container walls, contamination and the presence of acids and alkalis.
Non-contact capacitive level sensor with small diameter.

Question: What is the load capacity of the contacts of the output of the sensor ? whether it is possible to include in the circuit, for example, a relay/contactor. About what supply voltage ?
Question: Hello Botland, a valve is to be controlled via Arduino when a certain liquid level is reached. The liquid is in a glass cylinder (D=30mm) could this work with the sensor? The liquids are organic solvents such as hexane or dichloromethane. What interferes with the capacitive measurement? vg Micha
Question: Hello, I wanted to ask how is the case of working of this sensor with metal tanks? I need such a device to detect the liquid level of condensed refrigerant in a metal tank.
