AUF772 Series
The AUF772 Series sanitary-type ultrasonic flowmeter adopts materials and new processes that meet the sanitary requirements of food industry. It uses stainless steel housing and clamp connection, which is easy to disassemble and clean. And it can effectively prevent pollution during using and the residues in the measuring tube.
AUF772 can be widely used in food production processes such as mineral water, soy sauce, jam, beer, juice, rice wine and milk, as well as in the fields of sanitation and chemical industry.
