# **Dataset Description**
This dataset was created to support Article X and is available on [Roboflow](https://universe.roboflow.com/visiongauge/utm_dataset-ooorv) and [Hugging Face](https://huggingface.co/datasets/claytonsds/UTM_Dataset).
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.
