Product Usage Instructions

• On-Site Calibration
  • After installing the turbine flowmeter at the designated location, calibrate the flowmeter under actual working conditions to improve its measurement accuracy and precision.
• To perform on-site calibration:
  • Press the CALIBRATE (C) and DISPLAY (D) keys simultaneously to view the coefficient of the flowmeter.
  • Hold down the CALIBRATE (C) key for 5 seconds to enter the coefficient setting mode. The coefficient will blink.
  • Use the DISPLAY (D) key to adjust the coefficient and the CALIBRATE (C) key to switch coefficients.
  • After adjustment, wait for 10 seconds for the mode to automatically exit.
• The Calibration Formula for the Flowmeter
  • Calibrated Coefficient = Actual Flow Rate / Displayed Flow Rate Coefficient Before Calibration.
  • For example, if the flowmeter displays 98L when testing 100L of liquid, and the coefficient is displayed as 1000, the coefficient should be adjusted to: 100L / 98L * 1000 = 1020.
• Other Settings Adjustments
  • Reset Single Time Metering
  • Press the DISPLAY (D) key once.
  • Check Total Accumulated
  • Under the Initial Interface Display, press the CALIBRATE (C) key once to enter the total accumulated display (TOTAL).
  • To return to the Initial Interface Display, press the CALIBRATE (C) key again.
• Reset Total Accumulated
  • Press and hold the DISPLAY (D) key for 5 seconds to clear the total accumulated value.
• Metering Unit Setting
  • To set the metering unit:
  • Press and hold the DISPLAY (D) key for 5 seconds to enter the unit setting mode.
  • Use the CALIBRATE (C) key to switch between units.
  • Release the DISPLAY (D) key to save the selected unit.
• FAQ – Frequently Asked Questions
  • No change in flow rate Possible solutions:
  • 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
  • Possible solutions:
  • Increase the flow of the medium.
  • Replace with a flow meter of a smaller range.
  • The screen does not display text
  • Possible solutions:
  • Check if the battery is detached or out of power.
  • If the chip is damaged, replace it.

FUNCTION

TWO FORMS OF USE

ON-SITE CALIBRATION

• After installing the turbine flowmeter at the designated location, calibrate the flowmeter under actual working conditions to improve its measurement accuracy and precision.
• On-site calibration requires adjusting the coefficient of the flowmeter.
• Pressing the C and D keys simultaneously allows you to view the coefficient of the flowmeter.
• 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 and the C key to switch coefficients.
• After adjustment, wait for 10 seconds for the mode to automatically exit.

THE CALIBRATION FORMULA FOR THE FLOWMETER

• Calibrated Coefficient = Actual Flow Rate / Displayed Flow Rate * Coefficient Before Calibration.
• For example, if the flowmeter displays 98L when testing 100L of liquid, and the coefficient is displayed as 1000, the coefficient should be adjusted to: 100L / 98L * 1000 ≈ 1020.

INITIAL COEFFICIENTS

• The initial coefficients for the 1″ flowmeter, 2.5″ flowmeter, and 3″ flowmeter are all 1000; the initial coefficient for the 1.5″ flowmeter is 1850; the initial coefficient for the 2″ flowmeter is 4900.

OTHER SETTINGS ADJUSTMENTS

Reset Single Time Metering

• Press the D key once.

Check Total Accumulated

• Under the “Initial Interface Display,” press the C key once to enter the total accumulated display (TOTAL). To return to the “Initial Interface Display,” press the C key again.

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 metering unit at the factory is ITR (liters), and 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.
