BlueBot Max Series Flow Sensor
1 Overview
FS LoRa Series flow sensor is made with LoRa wireless communication technology and supports LoRaWAN communication protocol. It has low power consumption, long transmission distance and strong penetration ability. This equipment uses the measurement principle of the transit time method and combines Gentos’ ultrasonic flow algorithm technology to measure the fluid flow in the pipeline.
The product is designed with an integrated clamp-on structure. Users only needs to clamp the flow sensor on the pipe section tested, and then use nylon cable tie to lock it automatically and the installation is completed quickly, which breaks through the cumbersome installation and use of the flow sensor in one fell swoop and reduces the trouble of on-site installation and various constraints.

5.2 Installation Instructions
1. Carefully read “Section 10. Measurement Site Selection”. After the designated location is selected, the area of the pipe installation point must be cleaned, and the dense part of the pipe material must be selected for installation.
2. Gentos’ special coupling pads are attached to the central part of the 2 sensors. During installation, peel off the release film. The sensor will squeeze the coupling pads to ensure that the sensor and the pipe wall are tightly fitted without air bubbles.
5.3 Meter Wiring
1. The instrument is equipped with a built-in battery and can be powered, charged, and used for serial communication through the Type-C port.
2. Users access the MP LoRaWAN Series flow sensor through a cloud server.

10 Measurement Site Selection
This product is the easiest and quickest in flow meter installation of all small pipe diameter. Just choose a suitable measurement point, clamp the sensor surface of the product on the pipe, and fasten the two ends with cable ties for measurement.
When selecting the measurement point, it is required to select the pipe section with uniform distribution of the fluid and flow field to ensure the measurement accuracy. When installing, the following principles should be followed:
l Choose the pipe section filled with fluid, such as a vertical section of pipe section (the fluid preferably flows upwards) or horizontal pipe section filled with fluid.
l The measurement point should choose a uniform straight pipe section that is within 10 diameters (10D) upstream and 5 diameters (5D) downstream. There are no valves, elbows, variable diameters and other devices that interfere with the flow field within this range. The length of the straight pipe section is recommended to adopt the values shown in the table below.
l To ensure that the temperature at the measuring point is within the operating range. l Fully consider the scaling condition on the inner wall of the pipe, try to select the pipe section without
scaling for measurement, and select the pipe section with uniform and dense pipe material, which is easy to transmit ultrasonic waves. l During installation, there should be no air bubbles or particles between the sensor and the pipe wall. For horizontal pipes, the sensor should be installed at the 3 o’clock and 9 o’clock positions, avoiding the part where the top of the pipe may have air bubbles.

11 Communication Protocol
The flow meter adopts the response communication method, the upper computer to send “command” way, ask the lower position flow meter to response. The asynchronous communication baud rate (main workstation, computer system, ultrasonic flow meter) is generally 9600bps. Single byte data format (10 bits): 1 start bit, 1 stop bit and 8 data bits. Check bit: NONE.
11.1 FUJI Protocol
The basic commands are represented by data strings and the end of the command is indicated by a carriage return line break .They are characterized by arbitrary data length. The commands commonly used are shown in the following table:

4. If there are multiple traffic tables in the data network at the same time, the basic command cannot be used alone, and must be prefixed with W before it can be used, otherwise it will cause multiple traffic tables to response at the same time, which may result in system confusion.
1P prefix
Character P can be added before each basic command to indicate that the returned data has CRC verification .The check sum is obtained by binary addition.
For example: If the return data of the command DI+ (CR)(The corresponding binary data are 44H, 49H, 2BH, 0DH)is+1234567E+0m3 (CR)(The corresponding binary data are 2BH31H32H33H34H35H 36H37H45H2BH30H6DH33H20H0DH0AH) the return data of the command PDI+ (CR) is +1234567E+0m3 !F7 (CR). “!” indicates that it is a sum character in front of it, and the checksum of two bytes is in the back (2BH+31H+32H+33H+34H+35H+ 36H+37H+45H+2BH+30H+6DH+33H+20H=(2)F7H).
Note that “!” can be preceded by no data, and a space character may be present.
2W prefix
The usage of W prefix: W + string address code(Must be 5-digit number) + basic command, digital string value range 0~65535 except 13 (0DH enter), 10(0AH line feed) 42(2AH*), 38(26H&). If access to the instantaneous flow rate of the flow meter No. 12345, issue the command W012345DV (CR), the corresponding binary codes are 57H31H32H33H34H35H44H56H0DH.
3&Functional symbols
& the function symbol can add up to five basic commands (prefixed with P) to form a composite command and transmit it to the flow meter, which responds at the same time. For example, to send back simultaneously 1. instantaneous flow rate; 2. instantaneous flow rate; 3. positive cumulative quantity; 4. negative cumulative quantity; and 5. net cumulative quantity with verification from the flow meter No. 4321, send the command as follows:
W04321PDQD&PDV&PDI+&PDI-&PDINCR
The data returned at the same time may be as follows:
+0.000000E+00m3/d! ACCR
+0.000000E+00m/s! 88CR
+1234567E+0m3! F7CR
+0.000000E+0m3! DACR
+0.000000E+0 m3! DACR

11.2 Lora Protocol Frame Format
The Lora protocol frame of this instrument is to split the data into hexadecimals and send it in a large-end data format. The following table format is identified by the low address from which the data is sent (Assuming that the starting address of the continuous data address is 0000, continuous storage of data in sequential order).
For example: Lora’s frames are composed of instantaneous flow, positive accumulation, instantaneous velocity, signal quality, and timestamp in turn. At the same time, we assume that the actual data is: 3.78m3/h, 1.42m3, 3.62m/s, 99, 2353401716, the sent data format is (100 times greater):
0x83 0x01 0x00 0x00 0x8e 0x00 0x00 0x00 0x46 0x01 0x63 0x74 0x0f 0x46 0x8c

The data before sending is:
