This product is a type of liquid level sensor that detects the attenuation of ultrasonic vibration applied to the tip of the sensor. The body is all stainless steel (SUS316L) and the movable part and rubber dampers unique to vibration sensors are not used at all, so it can be used inside a pressure vessel. It is possible to detect liquids such as beer and detergent that are prone to bubbles.
