Magnetic level gauge is a robust and reliable solution for continuous liquid level measurement in safety-critical and process control applications. Designed for harsh industrial environments, it provides clear visual indication and stable signal output without being affected by the physical or chemical properties of the medium, such as conductivity, dielectric constant, foam, or vapor.
Based on a proven magnetic coupling principle, the magnetic level gauge ensures accurate level monitoring for corrosive, toxic, flammable, or high-temperature liquids. It supports both single-phase level measurement and interface measurement of two liquids with different densities, making it suitable for complex industrial processes.
As a long-term partner in industrial measurement and control, Instrava supplies magnetic level gauges as part of complete level measurement solutions. By combining reliable products, flexible OEM / ODM capabilities, and close technical collaboration, we help customers improve process safety, operational efficiency, and system reliability. Instrava works closely with customers and OEM partners to deliver long-lasting magnetic level solutions tailored to real operating conditions.

Level Magnetic-Applications
Magnetic level gauges are widely used across diverse industrial settings, providing accurate and reliable liquid level monitoring:
Steam and hot water boilers, ensuring safe and precise water level control.
Wastewater treatment systems, offering corrosion-resistant and maintenance-free monitoring.
Filling and unloading containers in chemical, pharmaceutical, and food industries.
Chemical and petrochemical storage tanks, capable of handling corrosive and hazardous liquids.
Petroleum and petroleum product tanks, maintaining safe and accurate level measurement.
Oil-fired boilers and diesel fuel tanks, supporting energy and power generation facilities.
Generator sets and auxiliary fuel storage, ensuring reliable operation in remote or industrial sites.
Marine and aerospace fuel tanks, including submarines, helicopters, and ships, where space-efficient and safe level measurement is critical.
Magnetic Level Gauge-Measuring Principle
The magnetic level gauge consists of a measuring body, dual-colored display cylinder, scale, top and bottom flanges, magnetic float, and optional 4–20 mA transmitter. Based on the buoyancy principle, the magnetic float rises or falls with the liquid level, causing the dual-colored display cylinder to rotate and visually indicate the liquid level.
Each display cylinder features a two-color, axisymmetric design with a 10 mm distance between cylinders: the red side represents liquid, while the white side represents air. In addition to standard liquid level measurement, the magnetic level gauge can also accurately measure the interface between two liquids of different densities, making it ideal for chemical, petrochemical, and industrial applications.
Magnetic Levels-Product Structure
The magnetic level gauge features a modular and durable structure designed for reliable liquid level measurement in industrial environments. Its main components include:
Measuring Body: Houses the magnetic float and provides the chamber for the liquid, built from corrosion-resistant materials such as stainless steel or carbon steel with optional PTFE lining.
Magnetic Float: Moves with the liquid level based on buoyancy, transmitting the position to the external indicator via magnetic coupling.
Dual-Colored Display Cylinder: Shows liquid (red) and air (white) levels with a clear, axisymmetric design, enabling intuitive visual reading.
Scale/Ruler: Provides precise reference for manual level reading.
Top and Bottom Flanges: Allow secure mounting to tanks or vessels, ensuring leak-free operation.
Optional Transmitter (4–20 mA): Converts liquid level changes into electrical signals for remote monitoring and integration with control systems.
This structure ensures that the pengukur level magnetik operates reliably in harsh conditions, supports interface measurement between different liquids, and provides maintenance-free, long-term level monitoring.
