GPI Turbine Flow Meter Frequently Asked Questions and Answers

1. In which industries can GPI turbine flowmeters be used?

GPI turbine flowmeters are medium and small caliber flowmeters, especially suitable for reverse osmosis, distilled water machine, dosing machine and other water treatment industries, as well as beverage, pharmaceutical, chemical, oil and other industries for fluid mixing, metering and control.

2. Do I need to configure a microcomputer coupling unit with 4-20MA (#1251000-1) to form a complete turbine flowmeter?

Yes, because the 4-20MA module, pulse processing module and remote unit all require the turbine flowmeter to have a microcomputer coupling unit to provide pulse signals for them.

3. What does K-factor mean?

K-factor is the number of pulses output per measurement unit (gallon or liter). The unit is PPG and PPL (PPG is used when leaving the factory). It is the relationship factor between the rotor rotation and the actual flow rate when the flowmeter is flowing. It is an essential parameter for display and transmission.

4. Can I replace the microcomputer unit on one turbine flowmeter with another?

Yes, but on-site calibration may be required. In general, the microcomputer units on the same specification of the filling meter are usually interchangeable because their K-factors are the same or basically the same, but the microcomputer units on different specifications of the flowmeter need to be recalibrated on site due to different K-factors. Please contact the supplier or factory

5. The flow direction of the fluid is from right to left, but the flowmeter is from left or right. What should I do?

Remove the microcomputer unit on the flowmeter, rotate it 180 degrees and then install it, that is, turn it 180 degrees and install it.

6. Can only the microcomputer unit be replaced?

Yes, order the microcomputer unit from the supplier. Note that you must specify the model of the turbine flowmeter

7. Is the lithium battery on the turbine flowmeter subject to transportation restrictions by the US transportation department?

No, the Sanyo lithium battery on the turbine flowmeter is not subject to transportation restrictions. According to the regulations of the US Department of Transportation for Material Safety Data, Sanyo sealed lithium batteries fully comply with transportation regulations

8. How long can the lithium battery last?

At least 9,000 hours. It is recommended to replace it once a year

9. Can the flowmeter be calibrated for other fluids?

Of course, in most cases, if your flow meter has a calibration function, you can directly refer to the user manual for calibration.

10. Can you use a GPI turbine flow meter to measure gas?

No, the GPI turbine flow meter can only measure liquids .

11. Is the GPI turbine flow meter explosion-proof?

Even better than explosion-proof function, all A1 and A2 series flow meters, except for PVC and high-pressure stainless steel models, are FM certified and suitable for CLASSI, DIVI, all groups, which means that it cannot produce enough sparks.

12. Can the GPI turbine flow meter be installed vertically or horizontally?

Yes, in either direction.

13. Can the GPI turbine flow meter work indoors? Can the flow meter be powered externally?

Yes, GPI turbine flow meters have NEMA4 rating and protection, and can work in normal outdoor environments for many years. The flow meter can be powered externally. The G2 series flow meter can add a power module #125070-1 when using the pulse processing module #125060-1 to provide DC power to the flow meter.

14. Does the flow meter need a filter? Can it work under high pressure?

When the particle diameter in the liquid is greater than 125 microns (55 mesh), a filter is required. The G2 series can be field calibrated to work at 1500PSI (102BAR), or up to 3000PSI (204BAR) depending on the model. (end)
