Portalevel® MAX
This is a video demonstrating the Portalevel® Max ultrasonic liquid level indicator operating on a 45KG CO2 cylinder. The Portalevel® Max is our UL listed flagship model within our Portalevel® line.
The user took readings from the top of the cylinder to the lower part of the cylinder in order to identify a differential in readings between the gas phase and liquid phase. Higher readings were found in the gas phase so he proceeded to calibrate above level forming a full bar graph. He then proceeded to move down in methodical steps to identify the exact liquid/gas interface, accurate to 1.5mm +/-.
