Liquid Level


If you need to know the level of a liquid in a tank or cylinder but you can’t measure it directly because it is under pressure or hazardous then there is a way of using an ultrasonic radar to “look” through the side of walls of the container. The level of the liquid can be found by measuring the difference between the signal above and below the liquid level. We have pioneered this technology since 1996 and now the accuracy is good and works on a large range of liquids. There are many uses for this technology the most common use is for measuring the liquid levels in fire suppression systems. The extinguishant or agent is stored in cylinders coupled together and activated remotely. Knowing the level of the extinguishant in each cylinder is vital. There are only two ways of finding this level by weighing or using an ultrasonic radar. The most common and cheapest extinguishant is carbon dioxide, CO2 other agents are FM200™, NOVEC 1230™, old Halon Agents, FE-13™, FE-25™, NAF S III™ and all core Clean Agent Systems.

We have two models that will do this, the analogue PLI Plus and the digital PLI Digital.

The PLI Plus uses manual controls to operate the gauge and the PLI Digital is automatic and has ABS Type Approval.
