Optic liquid level meter FS-IR1902 can be used to replace mechanical type float switch with better level control accuracy and durability. This product is for liquid level sensing, convenient to get aware of liquid level and easy to adjust. Easy to install and easy to use. The photoelectric point level sensor FS-IR1902 uses the refraction and reflection of infrared light to distinguish the change of the liquid level. The structure is simple, the precision is high, and there is no mechanical part inside, so the reliability is high. The advantages are small volume, high sensitivity, low power consumption, no debugging, no calibration, no maintenance, corrosion resistance, high pressure resistance, high temperature resistance, etc.

Q: I'm trying to find a liquid level sensor for filling wine bottles. Is this small enough to fit inside the top of a wine bottle? Is it food safe? Thx

A: I don't think this will fit inside of a wine bottle. Also worth noting is that this item is no plug-and-play item. You will need to wire this water sensor up to other items for it to work.

Q: What is maximum and minimum working temperature range?

A: this is the temperature range -25℃-120℃

Q: Does the sensor work if it's placed on the side (horizontally) of the water level? e.g.On the external wall of a water bottle looking at the water.

A: The sensor only works in the vertical direction. Unless the seller thinks you can make a vertical wall of free standing water. This sensor is designed to measure water level in some kind of tank. The water rises until it touches the tip of the sensor and the sensor output changes. Primarily used in some aquarium auto top-off systems

Q:Can i use this for aquarium fish tank automatic water top off, if water level goes down this will activate a water pump to fill the water back level?

A: No you can't I tried, it more for a run dry sensor.
