1. Where to find a liquid flow controller?
2. The letter qb is added before the displayed value of the electromagnetic flowmeter.
The appearance of "QB" before the displayed value of the electromagnetic flowmeter is usually a manufacturers custom code or specific operating condition identification, and in rare cases, it may be a signal of equipment failure. 1. In most cases, this is a normal phenomenon when the manufacturer customizes the code or functional mode. "QB" represents the device entering a specific working mode or displaying specific parameters. • Standard operating condition flow rate: commonly used in gas measurement, "QB" may represent "standard operating condition flow rate" (Qn), which is the flow rate value converted to standard temperature and pressure and displayed separately from the operating condition flow rate (operating condition m ³/h). • Batch control mode: In quantitative control systems, "QB" may represent "Quantity Batch" mode, which is performing quantitative filling/batch processing operations. • Manufacturer specific identification: For example, some models of Kaifeng Instrument Factory use "QB" to represent analog output status, while some models of KROHNE represent special calibration mode. 2 In rare cases, the abnormal status prompt of the device may be a fault code: • Sensor abnormality: electrode contamination, lining damage, or chaotic empty tube status, such as triggering the "QB" alarm with basic energy (please refer to the specific model manual for confirmation) • Signal interference: When strong electromagnetic interference causes signal distortion, abnormal codes may be displayed, and grounding and shielding treatment suggestions need to be checked. 1 Priorit
3. How to correctly install and wire the Kaifeng electromagnetic flowmeter?
The correct method and wiring points for installing the Kaifeng electromagnetic flowmeter are as follows:
1. Installation requirements: The installation direction and electrode position sensor can be installed vertically, horizontally, or obliquely, but it is necessary to ensure that the center line of the two electrodes is in a horizontal state to avoid measurement errors caused by uneven distribution of the medium.
. When installed horizontally, the electrode must not be located directly above the pipeline (which may accumulate gas) or directly below (which may deposit solid particles). The installation position of the medium full tube requires ensuring the flow of the medium full tube to prevent gas adsorption on the electrode or the medium not filling the tube from affecting the measurement. If the medium is not fully filled in the pi
