+# U-Tube Manometer Dataset (2025–2026)
+
+This dataset contains images of **U-tube manometers** and is designed for **computer vision regression and classification tasks**, focusing on reading and interpreting liquid column levels.
+
+---
+
+## Dataset Summary
+
+The **U-Tube Manometer Dataset** consists of 20,000 images of U-tube manometers with visible water columns. The dataset is suitable for:
+
+* **Image Regression**: estimating the numerical value of the water column height
+* **Image Classification**: classifying images based on discrete column values or ranges
+
+Images are organized in a folder structure where the **label is encoded in the directory name**, representing the measured water column value.
+
+---
+
+## Supported Tasks
+
+* Image Regression
+* Image Classification
+
+---
+
+## Data Structure
+
+The dataset follows a standard split structure:
+
+```
+dataset/
+├── train/
+│   ├── 10.2/
+│   │   ├── image23.png
+│   │   └── ...
+│   ├── 10.4/
+│   └── ...
+├── validation/
+│   ├── 9.8/
+│   └── ...
+└── test/
+    ├── 10.0/
+    └── ...
+```
+
+* Each subfolder name corresponds to the **label value** (e.g., water column height).
+* Images inside the folder share the same label.
+
+---
+
+## Labels
+
+* **Type**: Numerical (float)
+* **Description**: Water column height (e.g., in centimeters or equivalent unit)
+* **Source**: Encoded directly in the directory name
+
+For classification tasks, labels can be treated as discrete classes.
+
+---
+
+## Dataset Size
+
+* **Total images**: 20,000
+
+---
+
+## Image Characteristics
+
+* RGB images
+* Varying lighting conditions
+* Varying working fluids (water, oil, water–ink mixtures)
+* Single U-tube manometer per image
+* Visible liquid columns and scale markings
+
+---
+
+## Intended Use
+
+This dataset is intended for:
+
+* Training and evaluating regression models for visual measurement
+* Benchmarking image-based gauge reading systems
+* Research in applied computer vision for instrumentation
+
+---
+
+## Limitations
+
+* Performance may vary under extreme lighting or occlusion conditions
