Транзит-время ультразвуковой расходомер

GENERAL ANJUN AFV series is a fixed mounted, transit-time ultrasonic Flowmeter, with clamp-on transducers for non-invasive liquid measurement. Our microprocessor based, user friendly, field programmable flow measurement technique allows no interruption of the process flow and has low installation costs. FEATURES -2 line LCD display with flowrate, totalizer & signal condition -Stores up 64 Day/Month/Year Totalizer daily value -Batch control function -Wide range velocities of 0.01 ± 32 m/s -Transducers for pipe size from 15 to 6000 mm -High accuracy of ±1.0% of reading -Transducers include magnet devise, for installation on metal pipe without -Data logger function, include date, totalizer, signal condition... etc -Response time less than 1 second SPECIFICATION Measuring Principle: Transit time difference Pipe Size: S Type : 15 mm 100 mm (1/2" 4") : M Type : 50 mm 700 mm (2" 28") : L Type : 300 mm 6000 mm (12" 240") : HS Type : 15 mm 100 mm (½" 4") : HM Type: 50 mm 1000 mm (2" 40") Pipe Material : Cast Iron, Stainless Steel, Ductile Iron Copper, PVC, Aluminum, Fiberglass... etc. Liner Material : Tar Epoxy, Rubber, Mortar, Polypropylene, Polystyrol, Polyethylene, Teflon... etc Display : 4 Line LCD with illumination.
