The chart reveals the non linearity in height to volume and thus why level in the tank accelerates as the tank gets closer to capacity. Creating a copy of the sheet to your own Google account will allow you to explore the calculations in the sheet without interference. This means if someone else happens to be tinkering the same time you are, well, results may vary. Using the RESTful web service actually populates a single instance of the Google Sheet within my Google account. Volume of 10,000, a radius of 10 and a level of 20 (totally full):.Volume of 200, a radius of 50 and a level of 75:.Volume of 200, a radius of 50 and a level of 50:.

Here are a few examples (the links will open a new browser window or tab): This produces the complete service query URL: For example, this link will return the result of a tank with a volume capacity of 100, a radius of 50 and a level of 25.

The above sheet's calculation is published as a type of RESTful web service. You can also access the calculator directly from your browser's address bar. You need to copy it to your Google account before you can use it as a spreadsheet. Thus, when the tank is beyond 50% level the solution presented here works, even though a negative triangle area has no physical meaning.įor reference and tinkering here is a Google Spreadsheet which includes formula derivation, calculator, data table, and a chart of level vs. Since it is subtracted from the sector's area in Equation R a negative value makes it additive. R - h becomes negative and thus, the calculated area of the triangle is negative (the second term in Equation P and Q). Yes, it does work, though a bit counter-intuitively. What happens when the liquid height exceeds the radius? In other words, does this work if level is greater than 50%? Replace h with the level transmitter's output, not forgetting to account for units, and the output will be the liquid volume. For a horizontal tank, the geometry does vary with height.Įquation T Equation T is the formula to be used in code. The vertical solution works because the tank's geometry does not vary with liquid height: it is always a circle of the same radius. That solution does not apply to a horizontal tank. The liquid volume calculation of a vertically configured cylindrical tank is relatively simple: calculate the percentage of tank height that is occupied by liquid, then take that percentage and multiply it by tank volume capacity. A link to a spreadsheet and web service is provided that performs the calculation with your inputs. By the end of this post, we will arrive at a simplified formula to be used in PLC code which converts liquid height to liquid volume. Since the level transmitter was existing and accurately reporting liquid height this challenge was solved by code alone. The liquid level was measured by a sonic level transmitter. The presentation of tank contents to the operators as liquid height was a poor choice indeed. This meant, for a given waste inflow rate, the tank would appear to fill slowly at mid point and then, as level increased, the fill rate would apparently accelerate. The manual time estimation proved to be difficult for Operations since the tank filled over the course of weeks and the heightof the liquid in the tank was monitored, not the volume. When this occurred, a mess had to be cleaned up and the agony of regulatory oversight paperwork infuriated management. If the truck was called too late, the tank would overflow into a secondary containment. If the truck was called too soon, money was wasted since the waste company charged a flat haul rate in addition to a per gallon charge. The operation needed an accurate "time to full" value since the waste had to be hauled off by tanker truck. Not all technical challenges need hardware.Įarly in my automation career I was tasked with automating the estimationof time until a horizontally mounted, cylindrical solvent waste collection tank reached capacity.
