<<<<< General Description >>>>> * MULF100 series is an advanced wall mount type ultrasonic liquid flow meter by the * technology of time transit signal transmission and receiving using the clamp-on onto * outer pipe while not cutting the pipe. It measures flow velocity of 0 to 10 meter per * second of liquids.
* The module of ultrasonic flow meter is full-digitally designed to measure flow and * heat/energy long-term on the line. <<<<< Measuring Principle >>>>>
* While the ultrasonic is transmitted into the pipe the fluid being flown, ultrasonic, which * is rapidly transmitted by flow of fluid (tab Up-stream¡æDown-stream), is proportional * as sound speed plus amount of fluid velocity.
* On the other hand the ultrasonic, which is transmitted reversely (tba Down-stream¡æ * Up-stream), is slowly transmitted by the difference of sonic and speed and fluid * velocity, therefore there is a time difference ¥Ät (tab-tba) generated. As delta time (¥Ät) * generated here is a relative coefficient of fluid velocity, while considering this as a * basic, estimating of averaged velocity (V), cross-sectional area of pipe (d), and then * the processing to make flow rate (Q) again. Here ultrasonic has a sonic's property, * and then pass through inside pipe depending on fluid's inherent velocity.
