In recent years, with the acceleration of heating energy-saving transformation process, the application of ultrasonic heat meter is more more extensive. Users need to measure the overall performance of ultrasonic heat meter when selecting. Let's take you through the advantages of ultrasonic heat meter.

　　Talking about the advantages of ultrasonic heat meter, we should first understand the structure composition of ultrasonic. Ultrasonic is used in the heat meter to measure the flow with "time difference method". The specific principle is: when the ultrasonic wave flows in the water together with the water, it will produce a time difference, compared with the normal speed, it will produce a time difference. Use the time difference to calculate the flow rate of the water, then multiply the flow rate by the pipe diameter to get the flow rate. So it is called "time difference method". This method requires strict time sequence control. Generally, the propagation speed of ultrasonic in water is 1500m / s. The time sequence control circuit should be calculated by the period of single-chip microcomputer, generally 10-12s. If the millisecond level is reached, a slight deviation will affect the measurement.

　　The transducer, which is the main part of ultrasonic flowmeter ultrasonic heat meter, is composed of piezoelectric material acoustic wedge, requires high strength, toughness aging resistance. At present, the price of a pair of imported transducers is about 200 yuan in the world. The price is too high, while the quality of domestic transducers with low price is guaranteed, there is no comparability with the quality of imported products.

　　advantage

　　1. afraid of blocking

　　The ultrasonic heat meter is afraid of blocking, which is beyond reproach, because it is close to the state of empty pipe, there are almost no flow blocking parts in the guide pipe.

　　2. Easy to install

　　If the external clamp type sensor plug-in type sensor is selected, it can be installed online with pressure, without damaging the pipeline, without stopping production construction, saving a lot of cost for the enterprise.

　　3. Convenient networking

　　All ultrasonic heat meters have 4-20mA output RS485 communication, which can be easily accessed to PLC other networks for configuration. Moreover, MBus wireless remote transmission ultrasonic heat meters are also available. The split type heat meter can also extend the wire, directly install the display meter in the control room for easy observation recording.
