Intuitive power display: The mechanical oil level gauge directly indicates the oil level height with a pointer and float, allowing simple and clear observation without any power supply. It immediately reflects the actual fluid level inside the tank. reliability in harsh environments: With a simple, electronics structure, the gauge delivers stable performance where electronic components may fail. It is not affected by electromagnetic interference, supports a wide temperature range, and maintains a low failure rate. Wide compatibility across fluids and containers: Designed for multiple fluid media, including fuel, lubricating oil, and water, as well as other nonviscous liquids. It can operate effectively in different types of containers and environments. Quick installation and easy use: Manufactured from good materials, the gauge enables fast and hassle installation. Its userfriendly design allows straightforward operation, making it a practical and dependable choice. Key attributes: function is mechanical level indication using a pointer and float; compatible with fuel, lubricating oil, water, and other nonviscous liquids; suitable for various containers and environments; no power requirement; easy installation and reliable performance. Typical applications Automotive fuel tanks and engine oil reservoirs where a simple, power level readout is desirable. Industrial machinery lubrication systems and cooling water tanks requiring robust, EMI level indication. Water storage tanks or process vessels in manufacturing or construction sites, and other containers handling nonviscous liquids.
