https://www.vetnurse.co.uk/f/nonclinical-discussions/16369/oxygen-tanks---help hi! i was just looking for some help here... i was working at one practice for 2 years and never really dealt with oxygen tanks but i have moved practices and i just don&#39;t know how to tell if they are full or empty sounds really bad and i&#39;m quiteen-USTelligent Community 10https://www.vetnurse.co.uk/thread/125989?ContentTypeID=1Mon, 23 Jan 2012 23:33:17 GMT1a0763ec-3885-442c-853e-6cef656dfec5:154c68c2-51e9-4358-a859-8403671fc33dGillian Mostyn<p>If they are all open and connected to the same regulator, won&#39;t they all empty at exactly the same time??? If you only have one open at one time, wouldn&#39;t you know when it is empty anyway?</p> <p>At our practice it is simple - new ones still have the plastic cap on, old ones don&#39;t!&nbsp; If a tank is empty and you change to a new one, we also have labels to hang on the empty tanks. Simples! <img src="http://www.vetnurse.co.uk/emoticons/new/Very_happy_smiley.png" alt="Big Smile" /></p> <p>The easiest way to tell the difference between an empty and a full cylinder is by its weight!&nbsp; If you can&#39;t budge it, it is full!</p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/125987?ContentTypeID=1Mon, 23 Jan 2012 22:33:00 GMT1a0763ec-3885-442c-853e-6cef656dfec5:fc813df3-394e-4ef5-9cf2-6e09e0c1c177kitty fox<p>yes it is piped, but 3 cylinders each are attached to the gauge. like 3 on one side and 3 on the other, when one bank is empty it get switched to the other side (if that makes sense). i can tell when all of the tanks(from reading the gauge)&nbsp;are empty but not singular tanks</p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/125982?ContentTypeID=1Mon, 23 Jan 2012 22:12:52 GMT1a0763ec-3885-442c-853e-6cef656dfec5:1832f4e6-b27a-4f75-8298-258c105b38b8Nick Shackleton <p>the only way to tell is to connect them to a regulator. is this a piped gas system? There should be one above where it connects to the system and there should be a gauge with a needle in it showing how full the cylinder is&nbsp;</p><div style="clear:both;"></div>
