Aalborg Glass Air Flow Tube Meter 0-150 / 200 psig / # P11S2-VA0A / water direct This unit comes from a working environment. I do not know much about these. I cannot assure that it will work exactly as it should, but if you are not satisfied you can return it (w/in 30 days). They appear nice on the inside and outside (as seen in pictures). Sorry, no cords come on this. Will ship international. Aalborg Glass Air Flow Tube Meter 0-150 / 200 psig / # P11S2-VA0A / water direct This unit comes from a working environment.
