Ultrasonic flow meter is a modern development of the new flow measurement instrument, The fluid which can spread the voice ,if  can be measured by  ultrasonic flow meter measurement;
Ultra Sonic Flowmeter can measure high-viscosity liquids, non-conductive liquid or the flow of gas , its principle is: the ultrasonic propagation velocity of fluid in the fluid flow rate will be measured with the change.Ultrasonic flow meter is the biggest advantage for large diameter flow measurement (diameter more than 2 meters), the probe temperature range: Normal: -20 ~+80℃ special: ＞+80 ~ +160℃      Accuracy: 1%
Smith3015 advanced ultrasonic flow meter type "of the time difference," measuring principle, through the use of ultrasonic pulse in the direction of liquid two transmission speed difference, in the pursuit of tubular fluid flow.
Ultrasonic flow meter adopt non-contact measurement, and measurement process in the pipeline without any contact with the liquid, and therefore are not subject to pressure from the liquid, corrosion, pollution, and many other factors.
 Flow meter internal menu and the design of the software take full account of a simple and practical features and easy to use. Through the instrument panel covered the 16 touch-button programming, large-screen LCD display with continuous background light features, ease conditions in the light of circumstances not read data. In the state of measurement can be continuously display the flow rate and cumulative flow. At the same time can be measured on the screen to see the date、 time、the remaining battery power and signal strength remaining. Instrument self-diagnostic function, suggesting that the corresponding error message. Real-time test data on the LCD screen in order to display graphics and statement formats, in the main menu can be set up to view the statistical values of the parameters and data values.
Flow meter has a year、 month、 day flow accumulation function .It can be recorded this year and five years ago, the previous 12 months and this month, 31 days and the day before the cumulative flow. Could be sewage, water, recycling water, paper pulp, mud, crude oil and water, purified water, acid-base fluid, chemical raw materials, such as on-site water flow test; the scene of other flow meter calibration.
Smith3015 type ultrasonic flow meter Another feature is its built-in data memory can store up to 50,000 data, automatically recorded interval is five seconds to one hour, measuring real-time data via RS232 interface downloaded to a computer for analysis or stored in the machines in the subsequent downloads, the largest memory can be divided into 20 named storage block, data storage block, block all necessary data can also concentrate on how to deal with the initiation and termination of record time in the internal instrument settings.
 Smith3015 type ultrasonic flow meter has 0/4-20mA output support for external data recorders use. By the configuration of a sensor can be installed on the angle or reflection mode, the specific installation under way at the scene of the circumstances, high-speed velocity sensor can be of great use. Instrument powered by internal rechargeable battery.

<2>Product Categories
By the use of methods can be divided into Smith3015 type ultrasonic flow meter handheld, portable and fixed three categories.
 Smith3015 / S portable ultrasonic flow meter with automatic data storage, measurement accuracy 、 all Chinese、 flexible operating characteristics, cost can be called world-class. Non-access touch measurement, applicable to all industrial environments, advanced electronic design and manufacturing techniques, to facilitate carrying exchanges, the two DC power supply, battery can be operated 24 hours a flexible user interface, using simple. RS-232, RS-485, micro-printer output .It is convenient to user-friendly preservation, 24-hour battery.
