1. User Manual for Tianxin TBQZ-300 Intelligent Gas Turbine Flow Meter: [1]

The core content of the user manual for Tianxin TBQZ-300 Intelligent Gas Turbine Flow Meter is as follows: Product Overview Tianxin TBQZ-300 Intelligent Gas Turbine Flow Meter is a high-precision flow measurement instrument suitable for flow measurement of industrial gases (such as natural gas, air, nitrogen, etc.). The core principle is to drive the turbine to rotate through gas flow, use sensors to detect the rotation speed of Weiling Que and convert it into flow signals, and combine intelligent modules to achieve data acquisition, processing, and transmission. Image: The overall appearance of the Tianxin TBQZ-300 flowmeter is characterized by high precision measurement. It adopts a double bearing supported turbine structure to reduce mechanical friction and ensure long-term stability. The measurement accuracy can reach ± 1.0%. Intelligent compensation: Equipped with temperature and pressure compensation modules, it can automatically correct the impact of gas density changes on measurement and adapt to different working conditions. Multi parameter output: supports pulse signal, 4-20mA current signal, RS485 digital signal output, compatible with DCS, PLC and other control systems. Self diagnostic function: Real time monitoring of turbine speed and sensor status, automatic alarm and storage of fault codes when abnormal. Explosion proof design: The shell is made of explosion-proof material and is suitable for flammable and explosive gas environments (such as ExdIICT6 level). Installation and commissioning requirements: The flowmeter should be installed horizontally to avoid tilting and causing turbine jamming. Sufficient straight pipe s

ections (upstream ≥ 10D, downstream ≥ 5D, D is the diameter of the pipeline) should be retained upstream and downstream to eliminate fluid disturbances. The installation location should be away from vibration sources, heat sources, and areas with strong electromagnetic interference. Wiring instructions: Connect the power cord (24V DC) to the "+" and "-" terminals, and connect the signal cord to the corresponding output terminal. The grounding wire needs to be separately connected to the equipment grounding terminal to ensure electrical safety. Debugging process: After powering on, observe the display screen and confirm that there are no alarm messages. Set basic information such as gas type and pipeline parameters through buttons or upper computer software. Inject gas for real flow calibration, adjust the coefficient to make the measured value consistent with the standard table. Figure: Schematic diagram of requirements for installing a straight pipe section of a flowmeter. Operation and maintenance. Daily operation: View real-time flow rate, cumulative flow rate, temperature, pressure and other parameters through a display screen or upper computer. Regularly record data for trend analysis or report generation. Maintenance cycle: Every 3 months: Check the flexibility of the turbine rotation and clean the impurities in the filter. Every 6 months: Verify the accuracy of the sensor and replace the sealing ring (if necessary). Every year: Conduct comprehensive testing of explosion-proof performance and update firmware (if there is a new version). Caution: It is forbidden to plug or unplug signal lines with power on to avoid damaging the circuit. When cleaning, use a dry soft cloth and do not use corrosive solvents. Image: Co
