Fluid flow rate = V​; sound wave velocity during transmission through the fluid = c​; interior pipe diameter = D,​ interior pipe cross section = A​. When ultrasonic waves are transmitted through water between probes A​ and B​, the forward and reverse flow directions produce a time differential that is proportional to the flow rate.

Flow rate is Q = v * A. If the interior pipe cross section is a circle, then Q= v＊(d² π/ 4). Therefore, the size of the pipe diameter and the flow accuracy have a great relationship.

● High-precision picosecond time difference measurement improves measuring accuracy

● Patented multi-stage trigger technology enhances anti-interference performance

● Automatic signal conditioning circuit adapts to a variety of applications

● Analogy 4-20 milliampere communications technology

● Can be extended to use Modbus, OPC Server, and other industry control protocols

● Simple interface

● In addition, metal/plastic probe bracket can be purchased to significantly improve the ease of installation and reliability of the probe, and to overcome the disadvantages of the straps being dislodged due to temperature and vibration loosening and shifting. At the same time, it improves the accuracy of traffic detection and stabilizes the detection result.

● This product uses the principle of time differentials in ultrasonic transmission through fluids to determine flow rate.

● Correctness of installation is the most important factor in determining the accuracy and stability of the ultrasonic flowmeter. Incorrect or unstable installation or configurations may cause measurement errors or even loss of measuring capability. Be sure to install and operate the flowmeter correctly.

● Please pay attention to the status of the power supply. This product uses 9 ~ 30 volts DC; it is recommended that the supply current be greater than 1 amp. Avoid sharing power supply with devices that may cause interference (inverters, motors, etc.) as much as possible to avoid measuring errors caused by the interference of ultrasonic receiving signals.

● Before using, all the values ​​of the initial setup in the input interface must be correctly set to operate. During normal operation, the light on the instrument panel will display green. If an error occurs, the light will display red. This signal can be used to determine whether the installation and settings are correct.

● The input parameters will not automatically save when they are set. If power is lost, the data will be lost. Be sure to execute the Save function to save data.

● After set-up is completed, before starting measurement, if possible, please perform zero calibration (Set Zero), due to differences in the physical characteristics of the probe, the electronic components of the error ... and many other reasons, will cause the upstream and downstream alternating signals slightly different, resulting in a time difference, it is necessary to execute a zero point correction routine to eliminate this time difference when the fluid is at rest.

The screen displays one of two interfaces: the output interface (to display measured values) or the input interface(to set system parameters). Use the leftmost button to switch between the two interfaces.

The panel on the meter includes an LCD screen, four buttons, and two LED indicators.

There are four buttons at the bottom of the screen; their corresponding functions are shown on the lower edge of the screen:

From left to right order of view: Button one:

● Switch the interface.

● Back to the previous level (the multi-level interface).

Button two:

● When < ​is displayed: Returns to the previous option or interface; moves between choices after entering the interface.

● When +​ is displayed: Edit the number.

Button three:

● Select the next menu or interface.

● When editing numbers, jump to the next digit.

Button four:

● When ENT​ is displayed: Press Enter to enter the selected menu.

● When SET​ is displayed: Press to set the content entered.

● When PAUSE​ is displayed: Press to pause measurement, Red light will flash.

● When START​ is displayed: Press to continue measurement and release PAUSE​ status.

Panel LED lights: STATUS​ indicates the working status of the instrument. Under normal operation, a bright green light will be displayed. If an error occurs, then a red light will be displayed.
