The more readings (intervals) in the dip readings, the more accurate the final result. Calculator displays the total volume, as well as occupied and free volumes depending on the liquid level. Calculator also has a built in volume convertor, if you need to convert like m3, liter, U.S Gallon. The PLC can then interpolate between the "above" and "below" readings using a look-up algorithm. The application works in two systems of measures: metric or imperial (US). 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.

If accuracy is important (critical in some industries), then there are 2 methods which can produce accurate results.ġ. Tank Calc Volume Calculator is a free tools app developed by RegalTanks that has 50,000+ downloads. 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). 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. To be honest, given the lack of detail provided, your post looks like a homework assignment.
