Circulating water metering
Thread Content
For a circulating water system with a flow rate of 1000 m3/h, what type of meter should be used? DN500 – can a water meter be used for this purpose?
Vortex flow meters can be used, but they seem a bit expensive
Ultrasonic flowmeters using the time difference method do not require any holes to be made; a clamp-on type is sufficient, and it is important to choose a reputable brand.
Large-diameter dry-type water meters can be used.
A DN300 mechanical water meter was used to measure circulating water; the quality of this water was not very good, which affected the service life of the meter.
Insertion-type electromagnetic flowmeter! The plug-in type electromagnet is what we use for our 1400 circulating water pipes! The results are still very satisfactory!
For the loop water flow rate of the poster, plug-in electromagnets are a good choice as they offer excellent cost-performance. 7th floor is correct!
For measuring the flow rate of industrial circulating water, differential pressure flow meters should be avoided as much as possible, since the high pressure loss leads to an increased load on the circulating water pumps. The best choices are electromagnetic flowmeters and clamp-on ultrasonic flowmeters; these two types of flowmeters have no internal resistance elements inside the measurement tube, so the pressure loss is negligible. They also offer adequate measurement accuracy along with a wide range of measurement capacities.
