What type of flow meter is suitable for measuring hot water?
Thread Content
Happy National Day to everyone. I have a question: what type of flow meter is suitable for measuring hot water? Medium: hot water; Temperature: less than 100 degrees; Pressure: less than 0.5 MPa. Considering long-term use, scaling will definitely form inside the flow meter. Are there any recommended flow meters?
Personally, I think electromagnetic flowmeters are okay, but the issue of scaling isn’t quite clear yet.
If you have the money, it is recommended to use an external ultrasonic flow meter.
What is the caliber? For large diameters, external-attachment ultrasonic flowmeters are generally used; orifice type flowmeters can also be chosen. For smaller diameters, electromagnetic flowmeters are typically used. If measurement is not required, orifice plate throttling devices can be utilized
For small apertures, use electromagnets; for larger apertures, use orifice plates – standard throttling elements that are cost-effective.
It is recommended to use electromagnetic type with PTFE lining, and the components must be separate. Experience it firsthand: integrated thermal protection that works consistently.
If the water is not particularly dirty, electromagnetic flowmeters definitely cannot be used; if it’s similar to tap water, it is recommended to use vortex flowmeters, or else differential pressure flowmeters
With a metal rotameter, scaling at the joints is no problem.
Electromagnetic flowmeters are the preferred choice; they have a 4F lining, are of a split-type design, and those with severe scaling are equipped with scraper electrodes
