How to make a u tube manometer

A water manometer is a handy gadget that can be used to test the pressure on propane and natural gas appliances, among other things. If you have a weak flame on your propane barbecue grill, but the tank is full and the valve is on all the way, your next step is to track down the mysterious lack of gas pressure. Are you thinking of a pitot tube Pitot tube - Wikipedia . A U-tube manometer measures pressure. In a pitot tube, the velocity is related to the pressure differential by a formula. Apr 25, 2017 · The manometer's inclined angle provides many advantages. A small or low amount of pressure against the inclined manometer will produce a large liquid movement relative to the tube's graduations. As a result, the graduation scale can be very precise--down to a hundredth of an inch accuracy. How to make a Manometer Pipe Major Brett Tidswell Forget the old water-meter, with a hose running up a board and the water level bouncing away while you try to work out what your instrument is doing. Let’s go high tech! First, let’s look at what this is and what it does. A manometer, which seems to be the most A manometer consisting of a U-shaped glass tube partly filled with a liquid of known specific gravity; when the legs of the manometer are connected to separate sources of pressure, the liquid rises in one leg and drops in the other; the difference between the levels is proportional to the difference in pressures and inversely proportional to the liquid's specific gravity. A manometer is a device that measures air pressure using a container with a "U"-shaped tube open at one or both ends. In a closed manometer, a sample of gas is introduced into one end, which is then capped. Then, a fluid of known density is poured into the other end.
