Ultrasonic flow transmitter is composed of three parts: ultrasonic transducer, electronic circuit and flow display and accumulation system. Ultrasonic transmitting transducer converts electrical energy into ultrasonic energy and transmits it into the measured fluid, the receiver receives the ultrasonic signal, amplified by the electronic circuit and converted into an electrical signal representing the flow rate to supply the display and accumulation instrument for display and accumulation. In this way, the detection and display of flow is realized.


The ultrasonic flow transmitter adopts the window software design to consolidate or subdivide all of the parameters entered, the instrument setup and measurement result displays into more than 100 independent windows. The operator can input parameters, modify settings or display measurement results by "visiting" a specific window. These windows are arranged by 2-digit serial numbers (including "+" sign) from 00~99, then to +0, +1, etc. Each window serial number, or so-called window ID code, has a defined meaning. For example, Window M11 indicates the parameter input for pipe outside diameter, while Window M25 indicates the mounting spacing between the transducers, etc..

The flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers.  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 pipe.



Ultrasonic flowmeter is a non-contact instrument, it can measure the flow of large diameter media can also be used for the measurement of media that are not easy to contact and observe. Its measurement accuracy is very high, almost independent of the interference of various parameters of the measured medium, especially can solve the measurement problem that other instruments can not solve, such as strong corrosive, non-conductive, radioactive and flammable and explosive media flow measurement problems.



•Substance limitations: Ultrasonic flowmeters cannot be used for heavily contaminated liquids or slurry.

• Higher upfront cost: Ultrasonic flowmeters are significantly more expensive than many of the other inline flowmeter options available today.
