Although both oil level gauges and liquid level gauges are measuring tools used to measure liquid height, they differ in terms of structure, application scenarios, usage, and price.

1. Functional difference: The main function of the oil level gauge is to ensure that the oil level in the tank is within a safe range and to prompt refueling in a timely manner; The main function of a liquid level gauge is to determine the tank capacity based on the liquid height and ensure the normal operation of industrial production.
 

2. Structural differences: Oil level gauges are usually designed specifically to measure the amount of oil in the tank, so most oil level gauges adopt leak proof, anti loosening and other structural designs, while liquid level gauges are specifically designed for monitoring general liquids such as storage tanks and containers, so the structure of liquid level gauges is diversified.
 

3. Differences in application scenarios: Oil level gauges are mainly suitable for mechanical equipment such as automobiles and some smaller containers, while liquid level gauges are suitable for various large containers such as storage tanks and water tanks in various industrial fields.
 

4. Economic differences: In terms of price, the oil level gauge is relatively cheap and can be purchased for only a few tens of yuan; And the price of the liquid level gauge is relatively expensive, requiring several hundred yuan or more.
