Seeking expert advice on double-flange differential pressure density meters

1. Double-flange pancake face – it can’t measure density accurately; well deserved. :P. . . You mean this gypsum-lime slurry, which is used to coat the diaphragm – it contaminates the flange; the flange becomes dirty. Of course, if it’s dirty, the measurements won’t be accurate. {:2_30:} 2. How to calibrate it? First, disassemble the gauge to inspect the diaphragm; then determine which gauge it belongs to, consult its manual, follow the on-site calibration procedures, take samples for testing, perform calculations, and input values. 3. I guess that cleaning and descaling the double-flange diaphragm will become a tough task for you in the future – the gypsum forms a hard crust, and it’s not easy to remove it. 4. Do you want to be freed? If you’re interested, take a look first at the desulfurization lime slurry density meter produced by our factory – its sensor diaphragm does not come into contact with the liquid! —— The diaphragm does not scale, the probe requires no maintenance, and it can operate continuously without failures for a very long time. Then you give a suggestion to your supervisor. :lol. Used ones – all great, all repeat customers. I’m lying to you; I’m a dog. .

I’ve encountered cases where pressure was taken at an obliquely upward position for density measurement, and it seems that most of these cases had problems; taking pressure at an obliquely upward position makes it easier for air to accumulate, resulting in inaccurate measurements.

I’m just worried about bubbles forming; the manufacturing process emphasizes that this is not allowed~~~~~~

Fresh environmental designs seem to be like this; those I’ve encountered were all from them, and they basically all had problems.

The anus acts as a barrier at the end of the rectum, and it’s impossible to hold back the gas, so little puffs of gas escape, right, guys? {:2_32:} The monkey sneered and said, \"A broken flange, a rotten gasket – can you really hold your breath?\" Is it worth worrying about bubbles? Stop daydreaming; bubbles do not affect the equal transmission of pressure. Bubbles are not so easy to seal either; someone with the right skills can use a transparent tube to create a testing setup and observe how the bubbles manage to escape from the flange gasket. .

Measuring density is very different from measuring liquid level. When measuring liquid level, the pressure differential gauge deals with changes in liquid level over the entire range, that is, pressure changes of several dozen to hundreds of kPa; accuracy is considered in this context. When measuring density, however, the pressure change resulting from changes in density is a very small value, usually around 1 kPa or 2 kPa. When discussing the accuracy of using a pressure differential gauge for density measurement, it is relative to this tiny value. Even a slight drift in the pressure differential gauge can result in significant errors in the density reading. 2. Is that double-flange, large-face, rough-skin rubbing plate instrument capable of measuring density accurately? Calibration concerns time stability; one can’t keep adjusting the clock from time to time just to meet the requirements for calibrating the instrument. There are so many people; he can’t figure out this relationship either, and he can’t assess the stability and accuracy of the double flanges. 3. When a flushing ring is used to clean the diaphragm of dirt, since the pressure is not applied evenly across the entire surface of the diaphragm, the flushing process results in residual stress on the diaphragm. This stress can cause two problems in terms of density measurement: first, it leads to deviations in the measured values, and second, the release of this stress induces additional time drift errors. What does my brother mean by saying these things? My brother said that every time it’s rinsed, the gauge needs to be calibrated, so frequent calibration is inevitable.

There’s some truth to it. So, to measure the slurry density, try to increase the distance between the double flanges and install a flushing ring; if that doesn’t work, use a fork-type density meter.

Tuning forks are also afraid of having debris attached to them. It will be more sensitive than a differential pressure gauge. A flushing ring is also required. . . It is said that once gypsum forms scale, the shell becomes very hard? I don’t know either if it’s easy to wash away.
