Discussion on Replacing the Float in Float Level Gauges

There is currently a float level gauge, which is intended to be used for measuring liquid levels; the following issues need to be determined: When using a liquid level float to measure levels, I believe that the original float is too light, so it is necessary to increase its weight after calculation (by how much exactly, and how to calculate it?) ), or replace the float (I personally think the gauge head can be reused); the main challenges lie in the offset distance for the upper and lower limits, as well as in how to calculate the weight accurately. Friends are welcome to discuss this. Medium gasoline: 0.70; Water: 1.0. Normal temperature and pressure – this refers to the level in the reflux tank used in oil refining. Flange spacing: 1000 mm
I think there’s no need to overthink it; just find a manufacturer and have a new float replaced.

Got it; the header is used to receive a parameter
Why is the density calculated as 0.85? Can we explore this in more depth?
Does this also need to be discussed in depth? It’s really strange. Have you graduated from high school?

The gauge of an immersive float level gauge is, in essence, a weight transmitter whose indication is inversely proportional to the measured value (inversely proportional; I repeat, it’s inversely proportional – important to say it three times). An input value of zero corresponds to an indication of 100%, while an input value at full scale results in an indication of 0%； Generally, the upper limit of the range at the time of manufacture is the weight of the float (the weight of the float when there is no liquid present) ； The lower range limit is the weight of the float when it is completely submerged (the weight of the float at full liquid level) ； Range is the difference between the weight of the buoy itself and its weight when it is completely submerged ； The adjustable range of measurement is the difference between the weight of the float when it is completely submerged at the lowest measurable density of the medium and its own weight, and the difference between that weight and the float’s own weight when it is completely submerged at the highest measurable density of the medium. As can be seen from the above analysis, increasing or decreasing the weight of the float merely applies an additional constant force to the weight transmitter throughout the entire measurement range; its effect is the same as that of \"shifting\" the instrument, and it has no impact on the measurements ； There is only one situation in which increasing the weight of the float makes sense: when the density of the medium being measured is greater than the density of the float, the float is no longer submerged but instead floats. In this case, the float: 1. can no longer remain vertically suspended ； 2. It no longer maintains a relationship between the level of immersion and weight. But at this point, even if the weight of the float is increased, the range of weight changes caused by fluctuations in liquid level will most likely exceed the adjustable range of the weight transmitter. So: changing the buoy weight is pointless.
Little bitch, he doesn’t know anything; what’s this nonsense about a density of 0.85? What’s the point of adding sand? If the buoy density is indeed set to 0.85, then the buoy will float on the water’s surface lying flat – there’s no need to measure the position of a hammer anymore! That little bitch – she doesn’t know anything; all she knows is how to tie two pigtails and act like a girl in order to sell herself sexually. Divider line--------------- A float level gauge consists of a thin rod or stick; to use it as a level indicator, it needs to be changed into a thicker, shorter rod, such that the length of the rod equals the range of the level measurement. Secondly, the total mass of the cylinder must not exceed the weight of the original cylinder; it should be in line with the principle of ≦, being as close as possible to the weight of the original cylinder. Third is the overall density of the cylinder, which must be greater than the density of the liquid in the sedimented layer; in this case, it needs to be higher than the density of water, which is 1, so a value of around 1.3 g/ml would be appropriate. Fourth is the calibration rule: when the float is submerged in fully light liquid, it corresponds to the zero level; when the float is submerged in fully heavy liquid, it corresponds to the full level. Friendly reminder: for calibrating level gauges, actual measurement of the incoming fluid is the key. Don’t make any random calculations at all. Don’t make any random calculations at all. Don’t make any random calculations at all
Go and weigh the original float’s weight; once I know how the size of the float needs to be changed, I’ll tell you.
Yes, the two illiterates should hurry up and have an in-depth discussion. It’s best to buy more of his watches; they are all high-tech, top-notch watches.
