Magnetic Float Level Gauge
The magnetic float level gauge is an essential instrument for industrial liquid level measurement. It operates by using a magnetic float that moves along the guide tube, transferring liquid level changes to an indicator or signal output device.
Ideal for chemical, oil, water, and corrosive liquid applications, it provides reliable and continuous monitoring of tank levels. The device is designed with robust materials, ensuring excellent durability even under high pressure or harsh environments.
With both direct visual readings and remote electrical outputs, this level gauge supports integration into modern automation systems, helping industries achieve efficient process control.

What types of liquids can the Float Level Gauge measure?
The Float Level Gauge can measure water, oils, acids, alkalis, corrosive chemicals, and viscous fluids. It is suitable for a wide range of industrial applications, including chemical, petrochemical, and food processing environments.
How accurate is the Magnetic Float Level Meter?
Using precision float and guide rod design, this meter provides ±10 mm measurement accuracy. It ensures reliable and long-term stable performance for industrial liquid level measurement applications.
Can the Float Level Gauge connect to automated control systems?
Yes, models with 4–20 mA signal output can integrate with PLC and DCS systems for real-time monitoring, supporting automated control and data logging in industrial processes.
How often should the Float Level Gauge be inspected or maintained?
Routine maintenance includes checking the float and seals every 6–12 months. For aggressive or viscous media, more frequent inspections may be required to maintain measurement accuracy.
What installation considerations are necessary for optimal performance?
Install the gauge vertically and ensure the float moves freely. Avoid contact with tank walls or turbulence in the liquid to maintain accurate and stable level readings.
Is the Float Level Gauge suitable for corrosive or viscous liquids?
Yes, with appropriate material selection such as stainless steel or corrosion-resistant alloys, the gauge can reliably measure aggressive, corrosive, or viscous fluids in industrial tanks.
