[Weekly Topic] Issue 1, August 2017……Detection of phosphate flow rate
Thread Content
This post was last edited by A student adrift in the sea of knowledge on 2017-8-7 at 19:24. Regarding the measurement of phosphate flow rates at around 20% and 50%, I’ve checked but haven’t found a satisfactory method for measurement; hence I’m bringing this up again for discussion and help! Pressure of 10 kilograms, around 70 degrees. We welcome everyone to participate actively; outstanding replies will have the chance to win Haichuan coins and charm points, among other rewards
Electromagnetic flowmeter from Rosemount; linings of ETFE or PTFE are available. Platinum-iridium electrodes can be used, as well as titanium electrodes
If the phosphate concentration changes, the electrical conductivity should also change, right? . Starting from the basic principles, I guess an electromagnetic flowmeter can’t measure anything accurately at all~~~ :P
Measure the conductivity of phosphate solutions at various concentrations; if it exceeds 20 us/cm, electromagnetic methods should be given priority
In the past, electromagnetic methods were used; the problem was that this type of flow meter failed when scale formed in the medium. If scale forms every day, it’s impossible to clean it every day. In a word, I still think it’s not the best choice.
You could try a capacitive electromagnetic flowmeter; it should work well, such as Yokogawa’s CA model.
Good idea! It only affects traffic, not the measurements?
Good idea! It only affects traffic, not the measurements? This thing can only be imported; it’s probably a bit expensive. It would be even better if there were sales volume.
