Product overview 

The HAWK magnetic level gauge (MLG) is widely applied in the monitoring and process control 

of liquid level and interface for many industries; such as petroleum, chemical, power, paper, 

metallurgy, water treatment etc. 

The SPI and TBI are the standard and special magnetic level gauges of HAWK. The products 

are suitable for real time, precise, safe and reliable continuous measurement of process level. 

The design adopts a 360° magnetic ring which is hermetically sealed and incompressible. 

The indicator uses hermetical sealed glass tube technology to clearly indicate the level, which 

eliminates the common problems of glass gauges, such as vapour, condensation and liquid 

leakage etc. 

Why Choose HAWK? 

• Global support and service 

• 24 month application guarantee 

• Fast quotations and deliveries 

• Innovative solutions for oil & gas applications 

• Support of all major communication protocols 

• Commissioning services - Remotely and on-site 

Principle 

Indication by magnetic 

bargraph 

Based on the principle of magnetic coupling and 

buoyancy, the magnetic level gauge provides real-time 

measurement for level and interface. 

HAWK’s Magnetic Level Gauge (MLG) is connected to a 

process vessel. Within the chamber is a float containing a 

360° magnetic ring. Outside of the chamber is an indicator 

equipped with a vacuum glass tube, which contains a 

bicoloured two-face magnetic bargraph. In response to 

the level movement, the float moves accordingly, forcing 

the magnetic bargraph to turn and change color. True 

liquid level is indicated or “read” from the corresponding 

point on the measuring scale.
