Selection methods for small-diameter sleep measurement devices
Thread Content
Denitration is carried out in the workshop; the pipes for ammonia water and ammonia water mixtures are DN25 pipes, with a pressure below 1 PMa. Which flow meter is better? I plan to use vortex flow meters; if the diameter doesn’t meet the requirements, I’ll go with a tapered design. Is there a better way? Economically, try to keep it below the price of imported vortex flow meters
Generally speaking, ammonia solution has a low electrical conductivity, so using an electromagnetic flowmeter may not be the best option; a vortex flowmeter represents the most cost-effective solution, and personally, I find vortex flowmeters to be excellent.
There’s one more thing to consider: ammonia water will evaporate some ammonia gas as the temperature changes, which can cause certain corrosion to the flow meter. You can determine the appropriate material for the vortex flow meter based on the level of ammonia present in the environment; if corrosion is a significant issue, a vortex flow meter made of polytetrafluoroethylene can be used.
