ZRN-100 ultrasonic flowmeter

ZRN-100 ultrasonic flowmeter

Product description:

I. Product Overview
ZRN-100 Ultrasonic flowmeter Based on ultrasonic transit-time principle, the use of low-voltage, multi-pulse, digital signal processing and error correction technology, measuring tube filled with a closed liquid flow meter. His use of advanced dual-balanced differential signal transmitter and receiver technology, make products more adapted to industrial site 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 good, installation, easy maintenance and many other advantages, the sensor has a convenient clamp-on installation, no damage to the pipeline site, for easy line installation, no maintenance, do not stop, direct line to install the plug-in ultrasonic flowmeter, high precision and ultra-precision tubes segment standard π-tube stage. Beijing Sino-Swiss can Instrument Technology Co., Ltd. as a professional ultrasonic flowmeter manufacturing enterprise, specializing in the production of handheld ultrasonic flowmeter, portable ultrasonic flowmeter, clamp-on Ultrasonic flowmeter , Plug-in ultrasonic flowmeter. Panel mounted and integrated, while a variety of output forms of communication to choose from. In recent years, Sino-Swiss can and have developed a meter for measuring open channels, drains, ditches, sewage outlet ZRN2000 series ultrasonic flowmeter, flowmeter and weir tank with the use of measuring the flow of water inside the open channel is mainly used to measure the wastewater treatment plant, sewage outfall rate things were units, city sewer flow and irrigation channels, etc ..
