What solution should be chosen for the ammonia water flow meter in the denitration process?
Thread Content
Flow rate: 20–30 kg/h, diameter: 10–15; the required accuracy is an error of 0.5 kg/h. It is said that electromagnetic types are used more frequently
An electromagnetic flowmeter is highly suitable for measuring ammonia solution; given the small pipe diameter, using other types of flowmeters would result in significant pressure losses due to throttling inside the pipes. Electromagnetic flowmeters have a wide range of applications, a broad flow measurement range, and no pressure loss, making them an excellent choice.
Electromagnetic flowmeters are a suitable choice; when installed in accordance with the requirements, the measurement error is less than the value you specified. A high-precision mass flow meter is also an option... but electromagnetic flow meters are preferred. The recommended selection is as follows: range of 0–40 Kg/h; electrode material (for low concentrations): stainless steel, titanium, Hastelloy ； Electrode material (high concentration): titanium, Hastelloy ； Lining: PTFE
Laminar mass flow meters can be used; they offer high precision for low flow rates, good repeatability, and a long service life
