FHS300 Wall Fixed High Accuracy Ultrasonic Flowmeter/Heat Meter

FHS300 is based on the original imported FPGA integrated circuit from America’s Intel corporation. Its algorithm belongs to combination of threshold comparison gate circuit delay method and high-speed ADC correlation method. The main advantage is reflected in clamp-on ultrasonic flow meter. It is different from other 99% domestic clamp-on ultrasonic flow meters which are using the outdated capacitor charging algorithm or using algorithm of either comparison or correlation alone. So, our FHS300 belongs to high-end transit-time ultrasonic flow meter. Its measuring frequency can be more than 300 times per second (domestic other 99% clamp-on ultrasonic flow meters are less than 50 times per second, or even just once per second). Its accuracy is strictly controlled to be better than 1.0%. Moreover, its tolerance rate to bubbles in the measured pipe has been greatly improved, and the maximum tolerance time for continuous bubbles or impurities is 5 seconds.
