What type of flow meter is suitable for measuring and controlling the flow of liquids with low flow rates but high viscosity?
I’m just waiting for good news; I don’t know either!
As long as the medium is not very dirty, positive-displacement pumps are the most suitable for such applications.
I checked the information available to me and the answers are as follows: For low flow rates: rotameters, miniature gear flow meters, and orifice plate flow meters. High-viscosity liquids: gear flow meters, worm gear flow meters, scraper flow meters, target flow meters. It can be seen from this that the micro elliptical gear flow meter is a fairly good choice. Another consideration is the selection among high-viscosity liquids; pay close attention to the minimum measurement range of these four types of flowmeters to determine whether they meet your requirements.
