As the fluid flows through the tube, the reflectors and ultrasonic sensors installed on both sides use time differences to detect the flow velocity.
The measured propagation time is accurately calibrated and displayed by the internal program designed by the Company.
Reflectors are also precisely machined to ensure non-interrupted transmission of ultrasonic waves without adsorbing any pollutant contained in the water.

Flow range: +/-0.03 ft/s ~ +/-40 ft/s (+/-0.01 m/s~ +/-12 m/s) Accuracy: +/-0.5% of measured value Repeatability: 0.15% Output: 4-20mA Internal lithium power supply: 10hours Pipe size range: 0.6â?³~240â?³(15mm~6000mm) Transducer: IP54, CP magnet portable transducer, 5m cable
[ 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.)

Acoustic pipe is the only specialized application in ultrasonic testing of reliable system in the market. Is the use of cold hard tube professional forming, use clamp pressure connection, spiral connection, flange connection means such as, in the concrete casting is reliable anti-seepage effect. The finished product usually include ultrasonic has standard length of steel tube and forming a method of connecting joint connection. Can reserve a channel make detection head can direct to the bottom of the pile foundation Double side double sealing clamp pressure acoustic pipe designed two convex chamfer on the female end, convex slot with the sealing ring, installations will this product of the pile into the socket mouth, then using special hydraulic clamp to both a convex slot extrusion and squeezed parts of the stress pipe after contraction deformation, two convex slot of deep into outer pipe between inner pipe material, thus effectively realized this product reliable connection: rubber sealing ring in the material also is extruded deformation stick take in two layer between the pipe played a good sealing function of insurance. Single head double clamp pressure acoustic pipe Single head double sealing clamp pressure acoustic sound at the end of the pipe joint welding in a molding of the pipe sound, another sound the tube into the groove of joints double entry, through the hydraulic pressure meet clamp force under pressure, make the pipe sound and joint firmly together. Pipe joint in the middle section has a double sealing ring, so can make the pipe sound more seal, use this warhead welding clamp pressure type of acoustic detecting tube fittings, only a clamp pressure can.
