1. How to adjust GPI turbine flowmeter parameters? GPI turbine flowmeter parameter adjustment requires three core steps: menu settings, sensor configuration, and calibration verification. The specific operation depends on the instrument model and operating conditions. 1. After entering the main menu for basic parameter settings (usually the default password is four "1"), you need to set: • Flow unit: such as m ³/h or L/min, note that the instantaneous and cumulative flow units need to match. • Decimal digits: Adjust the display digits according to accuracy requirements (such as 100.000m ³). • Small signal cutoff: generally set to less than 5% of the range to filter low flow interference

2. Sensor and signal configuration • Sensor type: must be consistent with the actual type (turbine, vortex street, etc.), otherwise it will cause measurement deviation. Signal type: 4-20mA output: select the "current signal" mode for infiltration. -Pulse output: Select "Pulse Signal" and set the pulse equivalent (e.g. 1 pulse=1L). • Instrument coefficient: directly input the factory calibration value, if not available, on-site calibration through a standard flow source is required

3. Advanced function debugging • Communication settings: configure RS485 address (01-99), baud rate (commonly 9600bps), and Modbus register. Alarm function: Set high/low flow alarm thresholds and switch output modes (normally open/normally closed). • Temperature and pressure compensation: If multi parameter measurement is required, the compensation coefficient needs to be entered after enabling

4. Calibration and verification • Zero point calibration: Manually reset to zero when there is no flow, ensuring that the displayed value is 0. Full

range calibration: Cong Baixiao introduces full range flow and compares the displayed value with the actual value. If there is a large deviation, the instrument coefficient needs to be adjusted. Current calibration: If the 4-20mA output exceeds the tolerance, adjust the adjustable resistor on the circuit board: - W3 (marked 202) and adjust the 4mA point. -W4 (marked as 502) adjusts the 20mA point

5. Menu setting operation. To enter the setting mode, use a specific combination of keys (such as pressing the function key+F key at the same time): - Set the instrument coefficient bit by bit: the upper row displays the pulse frequency, and the lower row inputs the coefficient value (format XXXXXX. XX). -Press the F key to switch settings, and once all settings are completed, the instrument panel will automatically return to working mode. -Accumulated total reset: Press the F key while working to reset.

3. What internal parameters of the vortex flowmeter need to be set during specific use? The amplifier of the vortex flowmeter varies depending on its function and version.

1、 A vortex flowmeter with simple functions includes the following parameter options: instrument coefficient, small signal cutoff, 4-20mA corresponding output range, sampling or damping time, cumulative reset, etc.

2、 The vortex flowmeter with comprehensive functions, in addition to the above, also includes the following parameter options: type of measuring medium, flow compensation setting, flow unit, type of output signal, temperature upper and lower limits, pressure upper and lower limits, local gas pressure, medium standard density, communication settings (such as trigger number, baud rat
