GRYVOZE Digital Turbine Flow Meter: Operation and Calibration
Understanding the GRYVOZE Flow Meter
The GRYVOZE digital turbine flow meter displays liquid flow information in two primary forms: Instantaneous Flow and Total Cumulative Flow. It features a clear key for resetting and query functions, and a display key for viewing information.
Key Features:
- Liquid Flow Direction Sign: Indicates the direction of liquid flow.
- Set/Query Key: Used for setting parameters and querying data.
- Unit: Displays the unit of measurement.
- Clear Key: Used to clear data or reset functions.
- CALIBRATE key: Referred to as the "C" key.
- DISPLAY key: Referred to as the "D" key.
Two Forms of Use:
- Instantaneous Flow: Displays the current flow rate (e.g., 0.956 L/min).
- Total Cumulative Flow: Displays the total accumulated flow (e.g., 8.986 Total Liters).
On-Site Calibration
To ensure measurement accuracy and precision, calibrate the flowmeter at its designated location under actual working conditions. This process involves adjusting the flowmeter's coefficient.
Calibration Procedure:
- Press the "C" and "D" keys simultaneously to view the current coefficient.
- Hold down the "C" key for 5 seconds to enter the coefficient setting mode. The coefficient will blink.
- Use the "D" key to adjust the coefficient.
- Use the "C" key to switch between digits for adjustment.
- After adjustment, wait for 10 seconds for the mode to exit automatically.
Calibration Formula:
Calibrated Coefficient = Actual Flow Rate / Displayed Flow Rate * Coefficient Before Calibration
Example: If the flowmeter displays 98L when testing 100L of liquid, and the initial coefficient is 1000, the new coefficient should be adjusted to: (100L / 98L) * 1000 ≈ 1020.
Initial Coefficients:
- 1" flowmeter, 2.5" flowmeter, and 3" flowmeter: 1000
- 1.5" flowmeter: 1850
- 2" flowmeter: 4900
Other Settings Adjustments
Reset Single Time Metering
Press the "D" key once to reset the single time metering.
Check Total Accumulated
Under the "Initial Interface Display," press the "C" key once to enter the total accumulated display (TOTAL). Press the "C" key again to return to the "Initial Interface Display."
Reset Total Accumulated
Press and hold the "D" key for 5 seconds to clear the total accumulated value.
Metering Unit Setting
Simultaneously press and hold the "C" and "D" keys for more than 5 seconds to enter the metering unit setting. The default unit is liters (ITR). You can switch between GAL (gallons), QTS (quarts), PTS (pints), L (liters), and m³.
Press the "C" key for 3 seconds to save and exit the metering unit setting.
Answers to Common Questions
| Issue | Possible Cause / Solution |
|---|---|
| No change in flow rate | Increase the flow of the medium. |
| Remove the turbine component and check for any foreign objects blocking it. | |
| If the sensor is damaged, replace the chip. | |
| Low flow rate | Increase the flow of the medium. |
| Replace with a flow meter of a smaller range. | |
| Screen not displaying text | Check if the battery is detached or out of power. |
| If the chip is damaged, replace it. |
