Integrated waterproof ultrasonic liquid level sensor DYP-L02

Short Description:

The L02 ultrasonic liquid level measurement sensor series breakthrough the traditional opening can installation method and achieved the real-time non-contact liquid level monitoring in a closed container. The sensor need be attached to the bottom center of the container to detect its liquid level height. or attached to the side wall of the container to detect whether there is liquid in the container at the monitoring point.

Product Detail

Product Specifications

Part Numbers


The feature of L02 module include 1 Millimeter resolution, 2cm to 200cm measurement range, Various connection type output optional: UART Automatic out, UART Controlled output, Switch output, PNP/NPN output.

The L02 Series module is a strong ultrasonic sensor component, The sensor is built in a compact and rugged plastic ABS housing and internal circuit potting treatment. which meets the IP67 waterproof standards.

1. The sensor dead band and its maximum detecting distance is different according to the container made of various material such as steel, glass, iron, Ceramics, non-foamed plastics, etc. in room temperature.

2. The sensor dead band and its maximum detecting distance is different according to the different thickness in the same container under room temperature.

3. The detecting value output of the liquid level is unstable if the liquid height is over maximum measurement range of the sensor or when the liquid level of the measured liquid is sloshing or tilted.

4. In order to obtain the best performance, Please ensure that the shape of the container needs to be relatively regular and the surface is relatively flat.
