详情描述
The side-mounted magnetostrictive liquid level gauge utilizes the Wiedemann effect principle of magnetostrictive liquid level gauges, adopting the installation method principle of the side flange connection of magnetic float level gauges. By employing modern advanced electronic technology, it precisely measures the time intervals between pulse waves to achieve the purpose of liquid level measurement. It particularly excels in ordinary environments such as small measurement ranges, normal temperatures, and pressures, making it unparalleled by other measurement methods.
The Magnetic Flipper Type Magnetic Permeameter Liquid Level Gauge is a high-tech intelligent liquid level gauge developed by our company based on the industrial field requirements and fully utilizing our technical accumulation in sensor signal processing, mathematical modeling, information computation, and intelligent communication. This liquid level gauge is a high-precision, long-range linear position measurement liquid level sensor manufactured using the magnetic permeameter principle. It can measure the liquid surface of storage tanks and, when paired with a magnetic flipper, can visually reflect the real-time liquid level inside the tank. It boasts high accuracy, strong environmental adaptability, high reliability, simple installation, and convenient maintenance. It is widely used in liquid level measurement fields such as petrochemicals, chemicals, food, and pharmaceuticals, and is gradually replacing other traditional liquid level instruments, becoming a better choice for liquid level measurement instruments.

Installation:
The standard magnetic expansion flip level gauge is fully configured and installed prior to shipment. In case of an existing installation, follow these steps to install after removing the original mounting structure:
1. Secure the display panel in the marked suitable position of the cavity and install the fixed hook on the clamp.
2. Install the level gauge at the hook position on one side of the cavity, adjust the zero point position of the level gauge and the display panel to align the two zero points precisely. (When installing, note that the measurement direction of the magnetostrictive level gauge should be consistent with the magnetic flip level gauge.)
3. Secure the hanger to firmly fix the level gauge.
4. If the distance from the gauge head to the end cover of the tank exceeds 300mm or the gauge head is made of stainless steel, a driver's throat bolt and hook are required to secure the gauge head, ensuring the on-site liquid level gauge does not loosen or fall off.
5. Clean off any deposits or stains from the surface during the level gauge installation process.
