1. Zhicheng YLJ-II Liquid Flow Measurement and Control Instrument Manual: [2]
The core content of the Zhicheng YLJ-II Liquid Flow Measurement and Control Instrument Manual is as follows:
1. Product Overview Zhicheng YLJ-II Liquid Flow Measurement and Control Instrument is a highly accurate and stable device used for liquid flow measurement and pure hood control. It is suitable for liquid flow monitoring and automation control scenarios in industrial production.
2. Usage: Installation requirements: The equipment should be installed on a horizontal and stable base to avoid vibration interference.
. Ensure that the sensor is tightly connected to the pipeline to prevent liquid leakage from affecting measurement accuracy. The installation environment should be kept away from strong electromagnetic fields (such as large motors and transformers) to reduce signal interference. Operation process: Power on self-test: After connecting the power, the device automatically performs hardware testing, the display interface lights up, and displays the initial parameters. Parameter setting: Set flow units (such as L/min, m ³/h), alarm thresholds, and other parameters through panel buttons or supporting software. Operation monitoring: Real time display of current traffic values, cumulative traffic, and device status, supporting data recording and export functions. Shutdown operation: Press and hold the power button for 3 seconds to complete the shutdown, avoiding direct power loss and data loss.III. Common faults and solutions Fault 1: Abnormal display (no display/garbled text) Reason: Poor power contact, damaged display screen or motherboard failure.
. Solution: Check the power cord connection, replac
4. Maintenance and upkeep Daily cleaning: Regularly wipe the equipment casing with a dry soft cloth to prevent liquid from seeping into the interior.
. Sensor maintenance: Check the sensor surface for impurities every 3 months and rinse with clean water if necessary (corrosive cleaning agents are prohibited). Calibration cycle: It is recommended to contact professionals every 12 months to conduct a comprehensive calibration of the equipment to ensure measurement accuracy.Fifth, precautions: It is strictly prohibited to plug or unplug sensor connection wires during device operation to avoid damaging the circuit.
. If it is not used for a long time, disconnect the power and remove the storage card, and store it in a dry and ventilated environment. Non professionals are not allowed to disassemble the equipment without authorization, otherwise it may affect the warranty terms. 6、 Technical parameter measurement range: 0.1-1000 L/min (optional according to model) Accuracy level: ± 0.5% FS (full range) Operati
