AUF770 Series

AUF770 sanitary type ultrasonic flowmeter adoptsmaterials and new processes that meet the sanitray requirements of food industry. It uses stainless steel housing and clamp connection, which is easy to disassembly and cleaning. And it can effectively prevent pollution during using and the residues in the measuring tube. AUF770 can be widely used in food production process such as mineral water, soy sauce, jam, beer, juice, rice wine and milk, as well as in the fields of sanitation and chemical industry.
