Small Pipe Ultrasonic Flowmeter for Copper / Steel / PVC
I INTRODUCTION
ML-F8 is very unique in its structural design. It uses a circular magnetic steel to achieve automatic connection during installation.It takes only 2-3 minutes to complete the whole process from installation to measurement. It also adopts the current popular OLED display, which makes it easy to read in low light conditions.
ML-F8 is widely used in the production process for flow measurement and monitoring. The application of the product continuously and effectively controls the flow of the fluid, so as to improve the yield of the product and even save the input of the personnel, bringing benefits to the production enterprise.
II. FEATURES
III. Working Principle
Ultrasonic flow meters use sound waves at a frequency beyond the range of hearing (typically 0.5, 1, or 4 MHz). This ultrasound signal is sent into a stream of flowing liquid by using wetted (insertion) transducers that make direct contact with the liquid or external (clamp-on) transducers that send the ultrasound through the pipe wall. Clamp-on ultrasonic flow meters allow users to measure the volumetric flow rate of a fluid in a pipe without having to penetrate the pipe which decreases installation and maintenance costs.
A typical transit-time ultrasonic liquid flow meter utilizes two ultrasonic transducers that function as both ultrasonic transmitter and receiver. The ultrasonic flow meter operates by alternately transmitting and receiving a burst of ultrasound between the two transducers by measuring the transit time that it takes for sound to travel between the two transducers in both directions. The difference in the transit time (∆ time) measured is directly proportional to the velocity of the liquid in the pipe.
