1. Detailed instructions for setting GKDL
The setting of GKDL related equipment should be selected according to the product type, mainly covering three types: electromagnetic flowmeter converters, quantitative controllers, and cooling water circulation devices. The specific setting situation is as follows:
1. Cologne electromagnetic flowmeter converter (including GKDL function) 1 Instrument range setting: press and hold the ">" key for 5 seconds to enter the "A QUICK SETUP" menu, then select "A4 ANALOG OUTPUTS" and adjust the "A3 range" parameter
2. Simulation function: • Flow simulation: select "B1 Simulation" in the "B Test" menu and enter the volume flow simulation value. • Frequency simulation: Enter "B Test" → "B1 Simulation" → "By frequency output X", enter the frequency value and start
3. Factory reset: Press and hold the ">" key for 5 seconds to enter the "C Setup" menu, select "C5 Device" → "C6 Special functions" → "C03 Load settings" → "factory settings"
4. Zero calibration operation: Select "C1 Processinput" → "C1 Calibration" → "C01 Zero calibration" in the "C Setup" menu to perform automatic zero calibration
5. Flow polarity setting: Enter "C Setup" → Select the flow direction (forward/reverse) from "C1 Processinput" to "C2 Filter", and adjust the parameters for pulsation filtering and noise filtering. Attention: The operation requires entering the menu through a combination of keys. It is recommended to refer to the official manual.
2. GKDL Quantitative Control Instrument (Guangzhou Guangkong Automation Equipment Co., Ltd.) 1 Basic parameters: • Measurement range: 0-100000, accuracy 0.2%. • Input signal: Supports 4-20mA, 0-10mA, 0-20mA current, 1-5V DC, 0-5V D
2. Function settings: • Alarm output: Set the upper and lower limits of instantaneous flow or preset alarms for cumulative flow. • Transmission output: Convert instantaneous flow into standard current/voltage signals. Pulse output: Provides cumulative flow pulse signals. Printing function: supports manual, timed, and alarm printing, requires hardware clock configuration. Network communication: Computer and instrument data exchange is achieved through fully transparent interfaces. Attention: The signal type and alarm threshold need to be adjusted according to the actual working conditions.
III. GKDL-20 Cooling Water Circulation Device (Gengyu Instrument) 1 Temperature control setting: • Constant temperature range: -25 ℃ to room temperature, accuracy ± 2 ℃. • Intelligent display: LCD screen displays temperature in real-time
2. Circulating pump parameters: • Flow rate: fixed 19L/min. • Nozzle design: Supports 360 ° rotation for easy system connection. Attention: The temperature control and circulation pump parameters are fixed designs and do not require frequent adjustments. For more detailed steps, it is recommended to contact the device manufacturer for official technical documentation.
2. Troubleshooting ideas for Cologne electromagnetic flowmeter
The troubleshooting ideas for Cologne electromagnetic flowmeter are as follows:
1. Debugging excitation frequency selection for fluctuation of electromagnetic flowmeter (IFC300): Cologne electromagnetic flowmeter is single frequency adjustable, which is equal to the power frequency multiplied by a nu
