tung độ kế
Definition
- Noun:
- Cathetometer: A scientific instrument used for precisely measuring vertical distances or differences in height between two points. It typically consists of a vertical scale and a horizontally mounted telescope that can be moved up and down.
Usage Examples
- Noun:
- Nhà khoa học sử dụng tung độ kế để đo chênh lệch mực chất lỏng. (The scientist used a cathetometer to measure the difference in liquid levels.)
- Tung độ kế là thiết bị quan trọng trong thí nghiệm vật lý. (The cathetometer is an important device in physics experiments.)
Advanced Usage
- Technical Context: In fields like metrology, physics, or engineering, a "tung độ kế" (cathetometer) is employed for high-precision vertical alignment or measuring the height of columns of liquid in manometers.
Variants and Related Words
- Máy đo độ cao chính xác: A descriptive phrase meaning "precision height measuring instrument," often used to explain the function of a "tung độ kế."
Synonyms
- Vertical height measurer: A descriptive synonym for the instrument's function.
- Precision altimeter: In specific technical contexts, though an altimeter typically measures altitude relative to a fixed datum.
Related Terms
- Thước đo độ cao: (Height gauge) A more general term for tools measuring height, which may lack the telescopic precision of a cathetometer.
- Phao đo: (Gauge float) A related component sometimes used in conjunction with liquid level measurement.
