Class - Model PLI Plus -Portable Liquid Level Gauge

The PLI PLUS™ Portable Liquid Level gauge is designed to offer a simple, accurate, rapid and reliable method of determining the liquid level of high or low pressure in different gasses.

This includes CO2, Halon, FM200, Propane and any liquefied gas under pressure, without the need to move or weigh the cylinders.

The PLI PLUS™ can be used on cylinders, pipework, and any single skinned holding vessel with up to 25mm thick walls. The unit will also indicate the level of oil or water in a container or tank. The PLI PLUS™ gives accurate results by generating an ultrasonic sound wave that travels through the container and into the fluid or liquified gas.

The pulse responds differently to the presence or absence of liquid. This indicates the level of the liquid.

There is no reduction in health and safety levels, and the risk of gas leaks during servicing is eliminated as cylinders remain active and in situ.

• Accuracy ±1mm
• Power boost facility for cylinders in poor condition and cylinder wall thickness selector for thick (>4mm) or thin (

• Operational weight – 680g
