Flow meter selection
Thread Content
The viscosity of the liquid is 50 times that of water, and its density is 1.3 times that of water; it contains no crystals or precipitates. Can a glass rotameter be used? If that doesn’t work, which type is more cost-effective?
Could you provide the pipe diameter, flow rate, and accuracy requirements?
According to the conditions you provided, there should be no theoretical problems……
I hope the original poster can provide information on the pipe diameter, flow rate, accuracy requirements, and electrical conductivity; only by considering all these factors can a suitable solution be proposed. Otherwise, it’s impossible to determine which type is more cost-effective based on the information you’ve given. Glass rotors are relatively inexpensive, but they also tend to have more problems. This is just my opinion – generally, the most economical option isn’t necessarily the most stable and suitable one.
0.5-1.0M3/h, pipe diameter 25
Pipe diameter DN25, flow rate 0.5–1.0 m3/h; the accuracy requirement is not high, 5% is acceptable.
It is used in many places; the pipe diameter is DN25, and the flow rate is 0.5–1.0 m3/h； Pipe diameter DN40, flow rate 10–15 m3/h ； It has good electrical conductivity. Since it’s not a crucial location, I don’t want to invest too much in it.
It is also used in many other places, with DN40, 50, and flow rates ranging from 10 to 20, and so on.

It depends on whether you need local display or remote control. With a precision level of 5, the rotor is sufficient for this purpose. For remote control, the rotor and orifice plate are not very different in terms of performance. Many manufacturers can produce standard orifice plates, which are inexpensive and offer guaranteed precision, satisfying both remote and local control requirements
