1. Communication settings for Shugu SGQ intelligent differential pressure flowmeter
The communication settings for Shugu SGQ intelligent differential pressure flowmeter need to be completed through the MODBUS protocol and MODSCAN software. Specific operation process:
1. Tool preparation software: MODSCAN (for reading data) Hardware: USB to serial converter (to ensure that the computer has serial communication capability)
2. Core setting steps: Confirm that the starting address of MODSCAN should start from 40425 (not 424), and the first four floating-point data can be directly read without additional conversion. Key Data Point Localization and Type Conversion Point 6 (Address 40430): Instantaneous Flow (Unit: Ton/Hour), Data Type: LONG. Point 11 (Address 40435): Yesterdays usage, data type is LONG. The 16th point (address 40440): Total cumulative traffic, data type is LONG. Note: The MODSCAN software itself does not support the LONG type and needs to be converted using the following method: Method 1: Split the LONG type into two 16 bit integers (high-order and low order), read them separately, and combine them for calculation. Method 2: Use third-party MODBUS tools or scripts that support LONG type for secondary processing. Hardware connection and parameter matching: Connect the flowmeter to the computer through a USB to serial cable, ensuring that the port number (such as COM
3, COM4) matches the port set in MODSCAN. Configure serial port parameters: baud rate (usually 9600), data bits (8 bits), stop bit (1 bit), no checksum (None).
3. Common problem handling: Abnormal data reading: Check if the address starts from 40425 and confirm that the serial port parameters are consistent with t
4. Precautions: Before modifying parameters, it is recommended to back up the original Kai Brother configuration to avoid device abnormalities caused by misoperation.
. If parameters need to be written (such as modifying addresses or ranges), it is necessary to ensure that MODSCAN supports write functionality and strictly follow the device manuals clever write range limitations. Through the above steps, the communication settings of the Shugu SGQ intelligent differential pressure flowmeter can be completed, achieving accurate reading of instantaneous flow rate, daily consumption, and total cumulative flow rate.2. Remote monitoring and management software system for battery powered electromagnetic flowmeter
GSM/GPRS remote monitoring and management software system is used in conjunction with MSG type battery powered electromagnetic flowmeter with remote transmission function.
. The system can not only receive and store flow meter data, but also perform statistical analysis on flow data, allowing users to easily and timely control the water usage at various flow measurement points in the area.1、 This Yushen system can query, analyze, and display the water usage of each measurement point in the form of charts or curves, allowing users to easily manage the water usage of each measurement point. When there is an abnormality in the water usage of the measurement point or when the battery power of t
