ZRN-100 ultrasonic flowmeter

ZRN-100 ultrasonic flowmeter

Product description:

ZRN-100 ultrasonic flowmeter / calorimeter is the ultrasonic transit-time principle, the use of low-voltage, multi-pulse, digital signal processing and error correction technology, measuring a closed tube filled with liquid flow meter. His use of advanced double-balanced differential signal transmitter, receiver technology, make products more adapted to industrial environment, more convenient, more accurate measurement is widely used in petroleum, chemical, steel, metallurgy, electric power, water supply and drainage, and other fields flow metering water and various liquid media.

ZRN-100 ultrasonic flow / heat meter with high accuracy, repeatability, installation, easy maintenance and many other advantages, the sensor has a convenient clamp-on, available online installation, maintenance, plug-in, high-precision and ultra-precision tubes segment Standard π-tube stage, including host Handheld Ultrasonic Flowmeter. Portable ultrasonic flowmeter , Wall-mounted ultrasonic flowmeter, panel mounted and integrated ultrasonic flowmeter , While a variety of output forms of communication are available. At the same time on the circuit processing using a number of new technology creatively to solve the interference problem drive, and make the measurement accuracy of up to 1% R, the product through the relevant departments identification, reached the international advanced level. Non-full pipe ultrasonic flowmeter for dissatisfaction pipe liquid flow in closed conduits solve measurement problems, but to fill the gap.
