GAOTek-UFM-108

Description

Overview

GAOTek insertion type ultrasonic flowmeter is based on the original imported FPGA integrated circuit from America’s Intel corporation. Its algorithm belongs to a combination of threshold comparison gate circuit delay method and high-speed ADC correlation method. The main advantage is reflected in the 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 It is different from other 99% domestic clamp-on ultrasonic flow meters which are using the outdated capacitor charging algorithm or using algorithm of either comparison or correlation alone.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 products belong to a 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.

 

Features

  • It can be operated in ambient temperature -50°F to 122 °F (-10 ° C to 50 ° C).
  • It has a dot matrix character backlit LCD display.
  • Double-shielded transducer cable.
  • It belongs to a high-end transit-time ultrasonic flow meter.
