Coltraco Ultrasonics has developed a range of patented solutions to speed up the cylinder-checking process without compromising on safety standards. The company manufactures two particular tools specifically for this purpose: the PortalevelÒ MAX Marine and the PortasteeleÒ Calculator application. Used in conjunction by a single person, Hunter claims, these two products can enable crew to identify a leaking cylinder (or one that has previously leaked agent) within as little as 30 seconds.
The first step is to place the Portalevel MAX Marine against the side of the cylinder. This 160mm (h) x 82mm (w) x 30mm (d) monitor pings an ultrasonic signal into the cylinder, which allows the user to “pinpoint the liquid level sensor of suppressant agent”, Hunter says. This data can be logged and saved for future transfer to a PC or similar device, and is time-stamped for authenticity, so that operators/owners and crew can prove that they have carried out adequate checks in compliance with existing safety regulations.
In this way, the liquid level height has been obtained. However, it is not a given that the user will know how to convert this figure to determine the weight and mass of the extinguishing agent – nor that they will have the time to sit down and manually calculate hundreds of such readings.
The second step, then, is to feed the data captured by the Portalevel MAX Marine into the Portasteele® Calculator app. Hunter elaborates: “The app can be installed on a 5” or 7” tablet. The user inputs information related to: the extinguishing agent type [ie, CO2, Novec 1230, etc]; the cylinder dimensions; the temperature of the agent; and the liquid level indicator. The Portasteele® app then instantly provides the agent’s weight.” This process can also be conducted vice versa, inputting the suppressant agent’s mass/weight to generate a reading for liquid level height.
