Shenyang Instrument Import and Export Co., Ltd. to provide E + H flow meter - ultrasonic flowmeter liquid, steam and gas measurement, is one of the most important areas on-site measurements. As a market leader in flow measurement, Endress + Hauser using a variety of measurement techniques tailored to customers the most appropriate solutions, including electromagnetic flowmeters, mass flowmeters, vortex flowmeters, ultrasonic flowmeter, thermal gas flowmeter and differential pressure flowmeters. Time ultrasonic flowmeter can measure the volume flow of conductive or non-conductive liquid. Bundled or line the flexibility to choose the two sensors, bundled as an externally mounted, non-contact measurement, easy to install, does not interfere with the process, for corrosive media, high pressure and health situations. Model: Prosonic Flow 91W Prosonic Flow 92F Prosonic Flow 93T Prosonic Flow 93C Prosonic Flow 93P Prosonic Flow 93W Prosonic Flow 91W Product description Proline Prosonic 91W bundled ultrasonic flowmeter, and bundled probe combination for measuring pipes of various calibres ( including small diameter pipe), is specifically designed for the measurement of water a safe and value of the product. Prosonic Flow 92F is the world's first loop-powered (two-wire) pipe ultrasonic flowmeter, this feature makes it easier to integrate with the system and provide more cost-effective. Precision cast stainless steel sensor can achieve ultra-high measurement accuracy, ± 0.3% of its volume flow measurement accuracy is the highest standard of such products. Applications are mainly used in water and wastewater measurements. Product performance and advantages of the process without interruption, no pressure loss reliable, safe, proven by the measurement techniques to facilitate change at any time to install pipeline DN50 to DN4000 pipeline installation tool has superior performance comes with guarantees precise through the practical application of the probe mounting location proven Proline transmitter (standard operating and electronic modules) intelligent design improves the efficiency of debugging and maintenance Prosonic Flow 91 (transmitter) two-line LCD display key operating power 85-260 VAC (50-60Hz) 20- 55VAC (50-60Hz), 16-62VDC Ambient temperature -20 ... 60 ℃ Protection class IP67 (NEMA 4X) Electrical isolation input, output and power supply circuit electrical isolation between the output current output of all (Hart, 0/4 ... 20mA) Pulse output status output Communication HART Accuracy ± 1 ... 2% or (Re> 10000) Zero: ± 7.5mm / s explosion-proof certification FM, CSA Prosonic flow W (sensor) diameter range DN50 ...
