For measuring bituminous materials, what flow meters do people choose?
Thread Content
The medium in question is a material similar to asphalt; it is solid at room temperature and turns liquid above 100 degrees. What is used to measure the flow rate of this material? Is it a target-type meter, or something else? Please recommend some reliable brands that have been used for this purpose, whether they are imported or domestic.
Mass flow meters with insulated jackets are widely used for asphalt; you can ask the supplier for their performance records
Mass flow meters are not effective for measuring asphalt-based media, as it is difficult to determine the density of such media; therefore, volumetric flow meters with jackets are used to prevent solidification.
Mass flow meters work quite well; some companies that produce carbon black as well as those in the road and bridge construction industry use them.
I have used it before; the asphalt needs to be thoroughly preheated and circulated before it enters the flow meter.
Jacketed mass flow meter, or wedge flow meter
A mass flow meter with a jacket should perform well; if there is no jacket, insulation can be added manually, with the insulation requirement being no less than 80°.
