![]() The more readings (intervals) in the dip readings, the more accurate the final result. The PLC can then interpolate between the "above" and "below" readings using a look-up algorithm. Concentrate more readings where the height changes most rapidly versus height. This method is independent of the density of the product. produce a "dip-table" by filling through a certified flowmeter, recording the liquid height at predetermined intervals. Of course this is only applicable to contents that have a constant density (weight per volume).Ģ. The PLC simply has to determine volume dependent on the density of the contents. mount the vessel on load cells, and use the weight to determine the volume. It is possible to calculate the volume of a frustum in cone bottom tanks. You can select from a variety of nine tank shapes, including standard rectangular and cylindrical tanks, as well as capsule and elliptical tanks. If accuracy is important (critical in some industries), then there are 2 methods which can produce accurate results.ġ. Using this tank volume calculator, you can effortlessly approximate the volume of your container. Dividing by 231, which is the number of cubic inches in a gallon, will tell you exactly how many gallons your tank will hold when filled to capacity. Press the ÷ button, then enter 231 and hit a second time. In your case you haven't specified whether your tank is tilted, most are, and where the height transducer is located (which does make a difference if the tank is tilted). Divide the tanks volume in cubic inches by 231 to convert to gallons. Very rarely are tanks perfectly "cylindrical", very rarely are they the diameters specified on the design drawings, and things do get massively complicated with dished ends, tilted tanks, conical bottoms, and "inclusions" such as mixer paddles, heat-exchanger coils etc. Whilst the maths may require inverse trig functions, none of the formulae are that complicated for a simple cylinder with flat ends.īut I have to make the point that working from the stated (or even measured) tank dimensions is not going to give the best accuracy. "Cuboid.To be honest, given the lack of detail provided, your post looks like a homework assignment. Given the diagonal, length and width find the height, volume and surface area of a rectangular prismįor more information on cuboids see: Weisstein, Eric W. Given the volume, length and width find the height, surface area, and diagonal of a rectangular prismĤ. Given the surface area, length and width find the height, volume and diagonal of a rectangular prismģ. Given the length, width and height find the volume, surface area and diagonal of a rectangular prismĢ. So you can find the volume of a cube or surface area of a cube by setting these values equal to each other. ![]()
