Product Description

Description  

Ultrasonic flow meter is designed to measure the velocity of liquid within a closed conduit. It uses the
well-known transit-time measurement principle, plus our proprietary signal processing and ultrasonic transceiving
technologies.
As shown in Figure 1, a pair of ultrasonic transducers which are mounted on the pipe upstream and down
stream respectively. Each transducer serves as both ultrasonic transmitter and receiver. The main unit operates
by alternately transmitting and receiving a coded burst of sound energy between the two transducers. The
transit-times in the upstream direction as well as in the downstream direction are measured. The difference of the
two transit times is directly and exactly related to the velocity and the liquid in the pipe.

Features
1. Non contact measuring instruments, compact packing and easy to carry;
2. Suitable for various sizes of pipes and the medium which is sound conductive;
3. Built-in Ni-MH battery, continually working up for more than 20 hours;
4. Flexible user interface and easy to use;
5. Print output: built-in thermal printer, achieve to print online or at a scheduled time;
6. Aluminum alloy protective case, can be used in harsh environment;
