【Help】What type of flow meter should be used for the product water and concentrate water from the first-stage reverse osmosis system in boilers?
Thread Content
The impellers I used before didn’t work well. Do any experts have any good recommendations?
Reverse osmosis water is purified water, and vortex flow meters, rotors, orifice plates, and turbines can be used (without considering hygiene requirements). Concentrated water is water with a high salt content; it’s similar to tap water. In addition to the methods mentioned above, electromagnetic methods can also be considered.
The parameters can be specified in more detail, such as temperature and pressure, as well as the reasons why the impeller (turbine flow meter) does not perform well. For RO produced water that is non-conductive, vortex flow meters as well as differential pressure types can be used. An electromagnetic flowmeter is a good choice for concentrated water!
The temperature is at room temperature; the issue lies in the large deviation from the rotameter
Even if the impeller isn’t perfect, it still has a precision of around 4%, right? . . I believe its actual accuracy is far superior to that of vortex flow meters.
An electromagnetic flowmeter will do in all cases. Concentrated water is measured using a conventional electromagnetic flowmeter, while the produced water is measured using a capacitive electromagnetic flowmeter, that is, an inductive electromagnetic flowmeter. High precision, good reliability, and virtually no pressure loss.
The conductivity of water produced by reverse osmosis is relatively low; electromagnetic meters cannot be used, while vortex flow meters, orifice plates, and metal tube float meters can all be employed. For the concentrated water stream, an electromagnetic flow meter is used. In impeller flowmeters, the shaft tends to wear out over time, resulting in errors. What level of precision does LZ require?
On our end, the reverse osmosis system uses a rotor, and the electromagnetic device for the concentrated water side should still be fine
