AUF620 Series

AUF620 Series The AUF620 Series is a portable transit-time ultrasonic flowmeter with clamp-on sensors for non-invasive liquid measurement. Based on microprocessor and programmable flow measurement techniques, the process flow can be accurately measured without interrupting the flow and with low installation costs. FEATURES 2 lines LCD display with flowrate, totalizer… Stores up 720 Hours / 365 Days / 36 Months / 10 Years of Totalizer value Wide range, velocities of 0.01 ~ +/-32 m/s Sensors for pipe size from 25-4000 mm Lithium Battery lasts for over 8 hours of continuous operation Maximum temperature 160 °C With RS485 communication and print function With self-calibration function, real-time measurement calibration Accurate and stable measurement Response time less than 1 second SPECIFICATION Measuring Principle : Transit time difference Pipe Size : NN Type: 25-4000 mm (1"-160") : HT Type: 25-4000 mm (1"-160") Pipe Material : Cast Iron, Stainless Steel, Ductile Iron Copper, PVC, Aluminum, Fiberglass, etc. Liner Material : Tar Epoxy, Rubber, Mortar, Polypropylene, Polystyrol, Polyethylene, Teflon, etc. Sensor Housing : S.S. 304 Temperatue : Sensor NN: -40~70 °C : Sensor HT: -40~160 °C Display : 2 Lines LCD with illumination Flowrate : 7 Digits with decimal point Totalizer : 8 Digits, Forward, Reverse & Net values Engineering Unit : m3, L, USgal, USbbl, ft3 Time Unit : sec, min, hour, day Other : Velocity, Date, Time, Signal condition Accuracy : +/-1% ~ +/-1.5% of reading (0.5-30 m/s) : +/-0.5% of reading (Online calibration) Repeatability : +/-0.2% of reading Protection Class Converter : IP52 Converter Housing : IP67 Sensor : IP68 (Submersible) Keypad : 17 Keys with tactile action Response Time : Less than 1 second Flow Velocity : 0.01~+/-32 m/s Resolution : 0.001 m/s Ambient Temperature : -20~50 °C Ambient Humidity : 90% RH or less Built-in Battery : 10.8 V Lithium Battery Operation Time : >8 Hours Charger : 90-260 VAC 50/60 Hz, 8-12 hours charging Data Storage : Operation parameters and totalizer figures are stored by EEPROM for more than 10 years Communication : RS485 (MODBUS) Print : Impact printer Print Content : Date, Time, Network ID, Flowrate, Totalizer Printer Paper : Needle printer professional paper 44 * 30 mm Cable Entry : Push-Pull self-latching connectors (coaxial 3 contacts) Power Consumption : Less than 3W Dimensions : 330 * 280 * 135 mm Weight : 2.5 kg (Converter) : 4.5 kg (Converter, Sensor…)
