Pulse Purge Type Level Gauge LAX
LAX is the world’s only liquid level gauge to adopt the pulse purge method to intermittently discharge compressed air. Together with digital signal processing and an automatic zero point correction function, LAX achieves high accuracy on par with the magnetic float type level gauge Level Master. At the same time, the ease of outfitting and versatile application in a variety of tanks, allows for application on a wide range of ship types. LAX also reduces air consumption and running costs.
From the tanks in the engine room to ballast tanks and ingress alarms, LAX can cover the entire ship from one L-Core, containing SV Units, power supply and transmitter box, and air supply unit.
Digital × AI technology solves the hysteresis problem
In measuring liquid levels in which a change in pressure is received at a diaphragm and electrically converted by a strain gauge, hysteresis (historical phenomenon) occurs in the detected electrical potential as the pressure rises or falls. Large margins of error in measurements lead to poor accuracy.
LAX solves the hysteresis problem by combining zero point correction of the pressure sensor in the L-Core, digital processing, and AI technologies. This enables a very high accuracy of ±10 mm.
In addition, an air pocket is created between the receiving surface of the diaphragm and the liquid, thus eliminating problems with electrolytic corrosion or calcium buildup.
