Correct use of ultrasonic flow meter
An ultrasonic flow meter is a meter that measures the flow by detecting the action of fluid flow on an ultrasonic beam (or ultrasonic pulse).
According to the principle of signal detection, ultrasonic flowmeter can be divided into propagation velocity difference method (direct time difference method, time difference method, phase difference method and frequency difference method), beam offset method, Doppler method, cross correlation method, spatial filtering method. And noise law, etc.
Ultrasonic flowmeter is the same as electromagnetic flowmeter. It is an unobstructed flowmeter because it does not have any obstruction parts. It is a kind of flowmeter suitable for solving difficult flow measurement problems, especially in large-diameter flow measurement. The advantage is that it is one of the fastest growing types of flow meters.
Ultrasonic flow meters use a clip-on sensor to measure liquid flow. The installation process is extremely simple and easy to operate.
1. Press the on button to turn on the flow meter and press the off button to turn off the flow meter.
2. When the flow meter is powered on, first run the self-diagnosis program to detect the hardware and software. If there is a fault, the corresponding error message is displayed.
Usually there will be no error message display, the flow meter will directly enter the commonly used window No. 01 (abbreviated as M01), showing the flow rate, instantaneous flow rate, positive cumulative flow value and signal strength, signal goodness, the flow meter will be broken The pipe parameters input before the electric power or the initial setting parameters are based on the work.
3, the flow meter measurement work program is always in the background of the use of the interface, that is to say, the flow measurement will not stop because the user wants to browse the window, only the user to make a new pipe measurement change parameters, the flow meter Will work according to the new parameters.
The flow meter adjusts the amplifier gain when new parameters are input or when the power is turned on.
Through this step, the flow meter will find a better state of collection. The user will see a process prompt with numbers 1, 2, and 3 in the lower right corner of the LCD display.
4. When the user adjusts the installed sensor, the flow meter will automatically adjust the signal.
5. All input parameters are recorded in NVRAM for 10 years until they are changed.
6. The ultrasonic flow meter continues to measure and accumulate flow regardless of which window is displayed.
Particularly suitable for flow balance testing and flow monitoring: drinking water, river water, sea water, cooling water, hot water, industrial sewage, lubricating oil, diesel, fuel chemical liquids, etc.
