Specifications
The AFU-800 Series Ultrasonic Flowmeter/BTU meter operates with a power supply of 85 ~260V AC at 50/60Hz and consumes less than 2W. It measures flow rates from 0 to ±30m/s and temperatures from -30 to 160℃, depending on the transducer. It supports pipe sizes from DN15 to DN3000 and materials like PVC, PP, and stainless steel, excluding SS316. The device features a 16-key membrane keypad, various unit options for flow and heat, and an accuracy of ±1.0% for flow and ±2.0% for heat. It has a response time of less than 1 second and a backlit LCD display.

Features
