Dataset Description

This dataset was created to support Article X and is available on Roboflow and Hugging Face.

It consists of images of U-tube manometers constructed using a transparent PVC water level hose (5/16" × 1 mm) and flexible measuring tape with a length of 150 cm (60 inches). The manometric fluids represented in the dataset include water, oil, and dyed water. The dataset is intended for testing ML models for reading liquid column levels.

The dataset includes 904 unique original images. All annotations were performed using the RoboFlow Annotate Tool, with label precision within ± 0.1 cm.

Dataset Split

• Test set: 904 images

Data Structure

The dataset follows a standard split structure:

dataset/
├── test/
│    ├── 10.0/
│    └── ...
└── dataset_mapping.csv

• Each subfolder name corresponds to the label value (e.g., water column height in centimeters).
• Images inside the folder share the same height value.
