Page 5: Product Liabilities And Quality Assurance
1.1 Product Liabilities and Quality Assurance The purchaser should judge by himself whether the flowmeter is applicable or not, and shall bear related responsibilities. The manufacturer would bear no responsibilities for any consequences arising from the purchaser’s misuse of the flowmeter. The purchaser may lose the rights for quality assurance if the flowmeter or the system is installed or operated in a wrong way.

1.2 Descriptions of the Flow Meter Caution! For your safety, please carefully read the following safety instructions before use. With this manual, you could set up correct operating conditions of this flowmeter to ensure safety and efficiency in use. Only certified personnel who have received related training are allowed to install, use, operate and maintain this flowmeter.
Page 7: Measuring Principle
2.2 Measuring Principle This series of ultrasonic flowmeter is an industrial time-difference type ultrasonic flowmeter. It applies the latest industrial-level PFGA, which extremely improves the signal sampling frequency and bubble tolerance rate; the self-developed TGA technology makes it be capable of dealing with more complex logic and calculation to provide more accurate and faster measurements, and ensures the flowmeter could endure non-continuous bubbles or impurities within 5 sec.

Chapter III Electrical Connections 3.1 Safety Prompts Warning! DO cut off the power before any electrical connections. Please pay attention to the power supply data on the nameplate. Caution! Please strictly comply with local professional health and safety regulations. Only trained personnel are allowed to operate the electrical equipment.
Page 9: Connecting Electrical Cables
Internal shield should be connected through the multi-stranded drain wire. It is recommended to use "RVVP" shield cables as electrical connection cables. The power cord should be connected from the hole on one side and the signal cable should come out from the hole on the other side.

4.3 Quick Start Basic settings We will take PVC pipe for example. Related parameters: Outer diameter 20mm, wall thickness 4mm, and material is PVC with no lining and the medium is room temperature water. Step1.Pipe Size setting M10 Pipe settings Input the outer diameter and wall thickness.
Page 13 Step 3. Measurement liquid setting M12 Medium Select liquid you measure on site and following liquid types are available in the menu: 0. Water 1. Other ((If you choose others, please input the liquid velocity) Step 4. Transducer type M13 Transducer No need to set here Step 5.
Page 14: Pipe Design And Selection
5.2 Pipe Design and Selection The following should be taken into account when selecting a pipe: 5.2.1 Installation Environment It’s better to install the flowmeter indoors; if you have to install it outdoors, you should take measures to avoid direct sunlight or rainwater. The flowmeter shall be installed away from high temperature, thermal radiation from equipment or corrosive gas.
Page 15 Caution! DO ensure that the flowmeter is filled. DO NOT make the liquid flow downwards vertically, or it may have bubbles. Caution! To ensure measurement accuracy of the flowmeter, try to satisfy the following requirements on the length of straight pipe sections installed nearby the flowmeter: upstream >20D, downstream>10D.

Install after valves Install on diameter-reduced pipe Install on diameter-expanded pipe 5.3 Transducer Installation 5.3.1 Transducer Installation Steps 1. Please set parameters of M10 and M12 according to the actual situation on site, and adjust the end distance of the sensor according to the installation distance of M14. As shown in the figure below.
Page 17 2. Fix the flow meter bottom part on the pipe on with the rubber strap supplied with the product. 3. Insert the four fixing brackets of flow meter top part into the corresponding holes.
Page 18 4. Lock screws to fix both top and bottom part of flow meter. 5. Insert the aviation plug of the upper cover into the corresponding position of the bottom cover and tighten it. Then the installation is complete.
Page 19 5.3.2 Confirmation on Installation Quality Enter M04 menu Status Status Signal Signal Sound Time Sound Time Status Sound Signal Time Signal strength (UP/DN indicates upstream/downstream transducer): Ultrasonic Flow Meter applies 00.0-99.0 to indicate corresponding signal strength, the bigger the value, the stronger the signal strength. In normal operation, the signal strength of the upstream/downstream transducer should be >85 as required.
Page 20 Sound velocity: Vel. value indicates the sound velocity and the actual sound velocity measured by the flowmeter. Under normal conditions, it should be close to the sound velocity shown in M12 menu. If the difference is too big, you should check the installation settings and whether it is properly installed or not.
Page 21: Chapter Vi Operation
Chapter VI Operation Note： The flowmeter would be calibrated and debugged before leaving factory, and its parameters would be set accurately. Please carefully read the instructions if necessary. Non-professionals are not allowed to operate the flowmeter. 6.1 Common Functions 6.1.1 How to Judge its Operating Status If it displays "*R", it indicates the flowmeter works normally.
Page 22 need to set zero point to improve the accuracy for small flow measurement. At the time, you need to cut zero point on site. Cut zero steps: M22 menu-Cut-1. Yes, it displays “success” if zero point is cut. and the flowmeter would return to M01 menu.
Page 23 the flow direction, you could set 1000 and 2000 as the minimum and maximum limit values respectively in M32 menu. However, when 0-4-20mA output is used while considering the flow direction, you should consider two different conditions; when the flow direction is reverse, the output current is 0~4mA;...

Page 31: Chapter Vii Common Faults And Troubleshooting
Chapter VII Common Faults and Troubleshooting Note: Each flowmeter would be strictly tested and checked before leaving factory. However, it would still fail to work because of incorrect operation, wrong settings or bad working conditions. The following shows the common faults happened in operation, and provides analysis and related solutions.
Page 32: Chapter Viii Communication Interface And Communication Protocol
Chapter VIII Communication Interface and Communication Protocol 8.1 General The flowmeter is provided with an UART protocol, and you also could operate by using RS- 485 Modbus. There are two basic structures you could choose for networking, i.e. only applying the analog current output method or directly applying the UART communication method of the flowmeter.
Page 33 8.3 Communication Protocol and its Use The flowmeter supports HL protocol and MODBUS protocol. 8.3.1. HL protocol The flowmeter applies HL communication protocol. The host device would request the flowmeter to respond after sending a “command”. Asynchronous communication baud rate (Main station: computer system;...
