[ CHARACTERISTICS ] Wide Beam Transducer (Broadband ultrasonic measurement function) Determine the transmission frequency by finding the resonance frequency of the pipe according to the outer diameter, material, and thickness of the pipe â?¢ Little error occurs due to stable signal reception â?¢ Excellent measurement stability even when there are air bubbles slurry (30% or less), scale generation, changing temperature and density. How to install â?¶Pipe Configuration (automatic correction of disturbance factors) â?¢ In actual industrial sites, sufficient straight pipe without interference is required for accurate flow measurement â?¢ If no sufficient straight pipe is secured ; - Re estimation of correction factors for disturbance factors and distances from disturbance factors, self compensation. - It has the same accuracy as that in which a sufficient intuition is secured even at a short distance from the disturbance factor. â?¶Other Functions * Diagnostic Menu (Self diagnosis function) * Auto Zero (Automatic zero adjustment function) * MultiPulse Transmission (Multi pulse function) * Liquid Class Menu (Fluid selection function) [ SPECIFICATIONS ] * Ultrasonic firing method : Wide beam * Flow measurement range : 0.0003 m/s ~ 30 m/s (by diameter) * Accuracy : HUF 2000N: within 0.5 ~ 1% (Normal / Precision sensor) HUF 2000DN: Within 0.5% (Precision sensor) * Measurable pipe diameter : 6.4 mm ~ 6,000 mm * Measurable pipe material : Steel, ABS, Aluminum, Black Iron, Brass, Cast Iron, Copper, Ductile, Glass, Hastelloy, etc. * Measurable fluid : Water, Wastewater, Oil (Turbidity 30,000 mg / L or less, Bubble 30% or less) * Power : 110 ~ 220 V AC / 60 Hz * Operating temperature : General sensor (40 ~ 120 â??), High temperature sensor (40 ~ 230â??), Indicator (18 ~ 60â??) * Display : HUF 2000N: 100 x 55 / HUF 2000DN: 120 x 64 * Display contents: Instantaneous flow rate (4 digit), Accumulated flow rate (8 digit), Flow rate (3 digit), Pressure (4 digit), Ultrasonic velocity (Vs ), Air volume (Air), Signal strength, * Flow / Time display unit : m3 & L / Forward & Reverse (--) / Second (s), Minute (min), Hour (h) & Day * Input signal : HUF 2000N: 1 pressure signal / HUF 2000DN: 2 4 ~20 mA, 2 RTDs * Output signal : 4~20 mA, Integrated pulse, RS232 / RS 485 MODBUS * Protection grade : Sensor: IP 68 / Indicator: IP 65 * Sensor cable length : Max. 600m * Storage content and capacity : Date, time, instantaneous flow rate, integrated flow rate, pressure, signal intensity, ultrasonic velocity, etc. Memory storage at regular intervals (5 sec. ~ 24 hrs.)
