Tianxin TDS-200B Intelligent Spiral Flow Meter User Manual The core anti vibration capacity is as follows:

1. Product Overview Tianxin TDS-200B Intelligent Spiral Flow Meter is a flow measurement instrument designed based on the principle of spiral vortex, suitable for flow measurement of gas media. Its core structure includes a vortex generator, sensors, and intelligent processing modules, which achieve flow conversion by detecting the frequency of vortices generated in the fluid. This product has the characteristics of high precision, strong anti-interference ability, and fast response speed, and is widely used in industrial gas metering, energy management, and other fields.

2. Instructions for use: Installation should cover mu chun. The installation position should be away from vibration sources and strong electromagnetic interference environments, ensuring that the fluid direction is consistent with the direction indicated on the flowmeter.

. The inner diameter of the pipeline should match the nominal diameter of the flow meter to avoid measurement errors caused by uneven flow velocity. During installation, it is necessary to maintain a horizontal or vertical state (according to the model requirements), and ensure that the length of the front and rear straight pipe sections meets the standard (usually 10D in the front, 5D in the back, and D is the pipe diameter). Parameter settings can be achieved through the matching operation panel or upper computer software to set the medium type, temperature/pressure compensation parameters, range, etc. The first use requires zero point calibration. The specific steps are: ensure tha Spiral flowmeter

t there is no medium flow in the pipeline, press and hold the "zero point calibration" button for 3 seconds, and complete the operation after the screen displays "calibration successful". After the daily operation is powered on, the instrument automatically enters the self-test program, displaying version information and sensor status. Real time traffic data is displayed on the LCD screen, supporting switching between instantaneous and cumulative traffic for viewing. Equipped with a 485 communication interface, it can be connected to systems such as PLC and DCS for remote monitoring.

III. Common fault solutions Fault phenomenon 1: Abnormal flow display (large fluctuation or zero return) Possible causes: sensor dust accumulation, pipeline vibration interference, medium containing water/impurities.

. Process: Close the valve, remove the sensor head, and clean the surface of the rotating body with a soft cloth. Check if the installation bracket is loose, reinforce and recalibrate. If the medium contains impurities, a filter needs to be installed in front of the flowmeter. Fault phenomenon 2: Communication interruption. Possible causes include loose wiring, address conflicts, and incorrect baud rate settings. Process: Check if the communication cable connection is secure, replace the backup cable for testing. Confirm that the device address is consistent with the upper computer configuration through the operation panel. Verify the baud rate (default 9600bps) and data format (8-bit data bits, 1-bit stop bit, no checksum). Fault phenomenon 3: Accumulated flow error exceeding the standard. Possible reasons: improper range setting, temperature/pressure compensation failure. Processing procedure: Re calculate the actual
