Description

Magnetic Flap Level Gauge – Overview

A magnetic flap level gauge is a reliable and highly visible liquid level indicator that combines magnetic coupling with color-coded flaps to provide an easy-to-read, real-time display of fluid levels in tanks and vessels. This gauge is especially suitable for harsh industrial environments where direct visual access may be limited or safety concerns prevent open sight glass use.

Key Features and Design

Magnetic Coupling Mechanism
A float inside the tank contains a magnet that moves vertically with the liquid level, actuating a series of external, bi-color flaps through a magnetic field without direct contact with the process fluid.
Color-Coded Flaps
Typically red and white or red and green flaps alternate to clearly indicate liquid presence (red) versus empty space (white/green), providing intuitive level visualization even from a distance.
Robust Construction
- Gauge body made of carbon steel, stainless steel, or aluminum with corrosion-resistant coatings.
- Flaps constructed from durable plastic or metal with UV and chemical resistance.
Connection Types
Flanged, threaded, or welded connections for secure mounting per ANSI, DIN, or JIS standards.
Optional Features
- Integrated temperature or pressure sensors
- Remote level transmitters for digital monitoring
- Explosion-proof designs for hazardous areas

Typical Applications

Chemical and petrochemical plants for corrosive liquids
Oil & gas storage tanks and separators
Power generation boiler water level monitoring
Food and beverage hygienic process tanks
Water treatment reservoirs and process tanks

Advantages

Non-contact measurement ensures no fluid contamination
High visibility with clear, color-coded flaps
Durable and resistant to harsh environments
Modular design allows easy maintenance and customization
Capable of remote monitoring integration
