Ultrasonic Clamp On Flow Meter for Liquids

I. INTRODUCTION
The energy consumed by the user is calculated by measuring the temperature and flow rate of the chilled water (or hot water) flowing through the pipe.Install an energy meter ML-E8 on the user's inlet pipe and install a temperature sensor on each of the inlet and outlet pipes. The energy is calculated by metering the amount of chilled water (or hot water) flowing through the pipe (ie, the flow rate and pipe size), and the temperature difference between the incoming and return water.

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.
