Magnetic level gauges and hydrostatic level gauges are two widely used instruments for industrial liquid level monitoring. Both technologies are mature and reliable, but they serve different purposes and are suitable for different process conditions.<\/p>\n

From an OEM manufacturer\u2019s perspective, understanding the differences between a magnetic level gauge and a hydrostatic level gauge is essential for selecting the right level measurement solution. This article compares the two types in terms of working principle, performance, installation, and application suitability.<\/p>\n

It consists of a float containing a permanent magnet that moves up and down inside a sealed chamber as the liquid level changes. External indicator flaps or a magnetic display track the float position to show the real-time level.<\/p>\n

Magnetic level gauges provide direct and intuitive level indication without requiring power supply or electronic signals.<\/p>\n

Hydrostatic level gauges<\/strong><\/a> measure liquid level based on pressure. The device senses the hydrostatic pressure generated by the height of the liquid column and converts it into a standard output signal such as 4\u201320 mA.<\/p>\n

This type of level gauge is an electronic measurement instrument and requires stable liquid density to ensure accurate readings.<\/p>\n
