Dear sea friends, are there any well-known brands at home and abroad that specialize in producing slide gauge flow meters?

Thread Content

Dear sea friends, I am looking for high-quality gauge flowmeters from both domestic and international manufacturers. There is a brand called Hefei Smith available, but the quality of its units is comparable to that of mass flowmeters; in such cases, it’s better to use mass flowmeters instead. In this operating condition, the medium is viscous, and insulation is required; once the temperature drops, crystallization occurs. If paddle flow meters and mass flow meters are not to be used, and if there are other recommendations, other types of flow meters can also be considered. Temperature: ℃ 90
Pressure: MPa(G) 0.4
Max Flow Rate: m3/h 1.2
Normal Flow Rate: m3/h 0.8
Min Flow Rate: m3/h
Viscosity at Operating Conditions: mPa.S
