Description:
1. How to read the reading of a natural gas flow meter? The reading of a natural gas flow meter mainly depends on the numbers and units displayed on the LCD screen. For a mechanical dial, it is necessary to observe the position of the pointer and the corresponding value of the scale. 1. Reading method of electronic flowmeter • Direct reading: LCD screen displays cumulative usage (unit m ³) and instantaneous flow (unit m ³/h) - common models such as Gold Card Intelligent G6 series, display divided into two rows: upward display cumulative measurement, downward display real-time flow - instruments with valve control function will alternately display the remaining amount (to be used in conjunction with IC card) Reading method for mechanical flowmeter - observe the scale indicated by the red pointer and calculate according to the multiple of x 0.1/x 1/x 10 marked on the dial - Example: If the x 1 pointer points to 3 and the x 10 pointer points to 5, the current reading is 53m ³ - Old membrane gas meters (such as the Dandong Sikai TM series) use a roller counter to directly read the black number 3 Precautions - Industrial and commercial turbine flow meters should pay attention to pressure compensation parameters (such as Tianxin Instrument TDS series standard condition flow=operating condition flow x pressure correction factor) - Ultrasonic flow meters with temperature compensation (such as Emerson Daniel series) need to confirm whether the display interface is switched to standard condition flow - Mechanical meters need to be photographed on the 1st of each month to avoid disputes Exception handling - If the E-01 code appears on the electronic meter, it indicates that the battery is under voltage and needs to be replaced by contacting the gas company. If the red pointer of the mechanical meter does not rotate, it may indicate that there is no airflow passing through the pipeline. If there is suspicion of inaccurate measurement, the gas company can be requested to use a bell type calibration device for on-site inspection. Ultrasonic flowmeter. Chinese manual for TDS-100P portable ultrasonic flowmeter: [1]
The core content of the Chinese manual for TDS-100P portable ultrasonic flowmeter is as follows:
I. Product Overview TDS-100P portable ultrasonic flowmeter is a high-precision, non-contact flow measurement instrument suitable for real-time monitoring of liquid flow in industrial pipelines. Its core advantages include non-invasive measurement: no need to cut off the pipeline or install sensors, it can be directly clamped on the outer wall of the pipeline to complete the measurement. Portable design: small size, light weight, supports rapid deployment and mobile measurement on site. High precision and stability: Adopting dual channel ultrasonic technology, it has strong anti-interference ability and measurement accuracy can reach ± 1%. Multi functional display: Built in LCD screen displays real-time parameters such as flow rate, flow velocity, and cumulative flow rate, supporting data storage and export.
2. Instructions for use Installation steps Selection of measurement points: Avoid interference areas such as pipeline bends and valves, and ensure that the length of the upstream and downstream straight pipe sections meets the requirements (usually more than 10 times the diameter of the pipeline).
. Clamp sensor: Install the sensor perpendicular to the pipeline axis, adjust the spacing according to the K value indica
