LM400 Magnetic Level Gauge

Professional English Translation (Technical Specifications):‌

Product Name:‌ LM400 Magnetic Level Gauge

Brand:‌ Shanghai Zanke Automation Co., Ltd.

Product Description:‌

The LM400 series magnetic level gauge consists of a measuring body, indicator column (with red/white magnetic flags), float, and flange cover, designed for liquid level measurement in various containers. Suitable for high-temperature, explosion-proof, corrosive, and food-grade applications.

Working Principle:‌

Utilizes top-mounted or side-mounted installation

Magnetic coupling system transfers liquid level changes to:

Visual indicators (rotating flags)

Level switches (alarm contacts)

Transmitters (4-20mA output)

Float movement drives magnetic flags to rotate 180° for clear level indication
