Parameter calibration process for plug-in electromagnetic meter remote control
1. Preparation work 1 Safety confirmation: The equipment has completely stopped running and the power has been cut off to prevent the risk of electric shock during operation Technical document preparation: Carefully read the meter and remote control manual, clarify the parameter definition and calibration range Tool preparation: equipped with necessary tools such as screwdrivers, standard flow meters, protective equipment, etc.
2. Calibration operation steps 1 Enter calibration mode - long press the "Mode+Confirm" button on the remote control (taking the Cologne IFC300 series as an example) to activate the calibration interface - observe the "CAL" symbol appearing on the meter display screen to enter successfully. 2. Parameter selection - select the target parameters through the remote control direction keys: • Flow coefficient (K-factor) • Zero Offset • Full Scale • Unit. 3. Numerical setting - enter new parameter values based on the measured data of the standard flowmeter - Example: DN100 pipe diameter has a standard coefficient of 128.5 pulses/m ³ at a flow rate of 0.5m/s. 4. Confirm storage - press the "ENT" button on the remote control to save the parameters - the display screen flashes 3 times to indicate successful storage. 5 Verification testing - Running equipment after power restoration - Comparing standard instrument readings, the error should be ≤ 0.5% (as required by GB/T 18659-2018) Exit mode - long press the "ESC" key for 5 seconds to return to the measurement interface
III. Precautions • Before calibration, the medium
IV. Abnormal handling: If the "ERR-05" code appears, it indicates that the sensor is abnormal and the electrode attachment needs to be checked; ERR-12 "indicates insufficient signal strength, and it should be checked whether the installation position meets the requirements of the front 10D and rear 5D straight pipe sections. Note: Due to significant brand differences, the specific key combinations require the Emerson Rosemount series to be operated using a HART protocol handheld device, while the Siemens Sitrans FM series requires specialized magnetic operating tools.
