What instrument is suitable for testing salt content?

As the title suggests, it refers to an evaporation and salt separation system in which the salt content in the fluid, obtained through a forced-circulation heat exchanger, is brought to a certain level before being sent to a centrifuge. Currently, manual sampling is rather cumbersome and prone to clogging the sampling port. It’s difficult to determine the optimal discharge point; if too little salt is precipitated by the system, there will be a large amount of water coming out of the centrifuge, while if too much salt precipitates, it will block the pipes. Are there any suitable instruments that can detect the concentration of suspended salt particles in a solution? Accuracy isn’t necessary; stability is enough. Installation at pipe ends or equipment outlets; operating temperature: 70°C–80°C, pressure: 0.3 Mpa.
What about salt, concentration, impurities...
The wastewater contains sodium chloride as a salt; the equipment is made of titanium grade 2. There are few other impurities, and it’s hard to say what they are. When it is precipitated out, it becomes a saturated solution. It is mainly to determine how much salt has precipitated? The temperature of the turbidimeter must not exceed 50 degrees, so I was wondering if anyone has any good suggestions.
You idiot, your speech is so messy.:P —— I watched it several times but still couldn’t understand: Are you trying to measure the salt content in the solution? Is it still necessary to measure the solid salt that has been precipitated, that is, the salt content in the saltwater mixture? .
Specialized salt-resistant turbidity or suspended solids concentration probes can be used. But this requires choosing the right installation conditions and location. The details can be discussed.
Bro, I think it’s clear enough, right? In this evaporation crystallization process, once the salt has crystallized to a certain extent, it needs to be placed in a centrifuge for separation. If this is done too early, the centrifuge will be filled with water; if it’s done too late, the salt will block the pipes. The measured salt content. Now, manual sampling is used; the sampling ports get clogged frequently, which is also labor-intensive. So please recommend suitable testing instruments that can measure the amount of salts precipitated online.
I asked a few companies these past two days, and all said they couldn’t do it.
1. Oh, my good brother, this time I finally understand! 2. By “the salt content determined through analysis,” I understand it to refer to measuring the average density of the saturated saltwater suspension. 3. If the density of the suspension is too low, not enough precipitate is formed, and the centrifuge operates uselessly. If the density is too high, too much precipitate forms, which can cause blockages in the pipes and lead to shutdowns for cleaning – again, this is inefficient. To ensure efficiency, it’s necessary to accurately control the density value, right? 4. Whatever task that foreign dogs can’t handle or determine accurately, I’m highly interested in tackling it~~~ Therefore, if you want to determine density with accuracy, you’ll probably need to turn to me :P I’ve been producing online density meters for 15 years, using them in power plant desulfurization processes, in drilling muds for oil and gas exploration, as well as in concrete and cement mortars used in mining. . . Bro, I also received a deposit of 13,600 yuan for the densitometer yesterday. :P 5: Please tell me about the situation with your evaporation container – share it with everyone; if you have meat at home, let others come and grab some to eat. :lol What is the range of fluctuations in vapor pressure? What is the temperature fluctuation range of the material solution? Is there stirring? —— If so, describe in detail the intensity of the swirling or tumbling of the liquid, the maximum liquid level height, the height of the tank, the diameter of the tank, or length×width. Is it permissible to mount the instrument on top? , or side-mounted? , or casually? .
I plan to install it at the outlet of the forced circulation pump, beneath the forced circulation heat exchanger; however, the heat exchanger cannot be installed there as the equipment is already in place there, and it contains tube bundles. Currently, samples are taken at the pump outlet manually, and there is a heavy workload at several locations ； Since it involves dealing with wastewater, which has a strong odor and can harm the health of operators, salt often clogs the sampling ports; therefore, the use of online monitoring instruments can eliminate the need for such personnel. This helps to reduce occupational diseases as well as save costs. As long as it runs stably, the price is negotiable.

Additionally, there is a transfer tank in front of the centrifuge after the heat exchanger, equipped with a stirrer. The height is 4 meters, with the liquid level not exceeding 3.5 meters. The agitator blades are located below the tank, and the instruments can be installed inside the equipment; it is preferable to install them on the outlet pipe.
