INTRODUCTION
| MEWOI-UDS200H-DN15-100 or DN50-700 or DN300-6000(-30~90°c) Clip Type Ultrasonic Flow Meter transit time flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other.The transducers can be mounted in V-method where the soundtransverses the pipe twice, or W-method where the sound transverses the pipe four times, or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once.This selection of the mounting method depends on pipe and liquid characteristics.The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the liquid in the pip |
