IP54 Clamp On Ultrasonic Flow Meter With OLED Display

IP54 Class Clamp On Ultrasonic Flow Meter with OLED Display

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.

• Clamp on type, no need to cut the pipe or do any other changes.
• No professional product knowledge required, installation and measurement can be done based on the guide.
• No moving parts or pressure changes involved, installation can be done without stop provide.

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.

Why choose ultrasonic?

Ease-of-Installation: The largest benefit of any “clamp-on” transit-time flow meter is the ease-of-installation. While still requiring sections of straight pipe upstream of the measurement location, the process does not require shutting the system down to install, making maintenance and upkeep of transit-time meters much more attractive.

Low maintenance: There are no blades to wear out or bearings to replace as in turbine meters, nor are there electrodes that can foul over time as in magnetic flow meters.
