Jianheng 1188 series fixed ultrasonic flowmeter? Velocity range: 0 ~ ± 12 m / s (0 ~ ± 40 ft / s)? Can be used for a "- 8" pipe? Accuracy: measured value ± 0.5%, (0.5 ~ 5m / s or 1.5 ~ 40 ft / s)? diameter range: DN25 ~ DN5000? 2GSD card, maximum storage time of 512 days? with modbus protocol [introduction] Jianheng 1188 Series Ultrasonic flow meter is using the latest digital technology multifunction time difference ultrasonic liquid flow meter for full pipe liquid medium continuous measurement. The all-digital ultrasonic flowmeter has no moving parts, high reliability, small amount of routine maintenance. Meter's microprocessor provides a unique model of digital coding and related testing procedures, can provide long-term drift-free measurement, and the measured liquid dynamic configuration based on different operating software to adjust the parameters. 08 version has been integrated built-in high-capacity mass storage, recording every moment of the traffic data change (can record up to 512 days historical data), greatly improving the credibility of the data accumulation. Jianheng 1188 series through the appropriate configuration options can achieve data acquisition, GPRS wireless data transmission, lightning protection and UPS backup power, is a truly versatile instrument!
