Question 1

How does a portable fuel flow meter work?

Accepted Answer

This one is a turbine type: fuel flowing through the meter spins a rotor, and rotor speed is directly proportional to flow velocity. The electronics convert rotation pulses into totalized volume. Turbine measurement suits clean, low-viscosity fuels (≤13 mm²/s) such as gasoline, diesel and kerosene, which is exactly the service this meter is designed for.

Question 2

Does temperature affect the reading?

Accepted Answer

Temperature doesn't change the metered volume, but it changes what that volume means — fuel expands and contracts with temperature, so 30,000 liters loaded warm at the depot is not 30,000 liters delivered cold. This meter measures oil temperature to ±0.1°C and automatically outputs V20, the volume corrected to 20°C, so delivered quantity can be compared with dispatch documents on the same basis.

Question 3

Will it slow down the unloading?

Accepted Answer

No. The meter connects into the gravity unloading line with quick couplings and passes 8–80 m³/h (34–340 GPM) through a DN80 bore — full unloading flow. An adapter set fits it to 2.5" outlets. After unloading, the vacuum fill valve and sight glass confirm no residual oil is held in the meter.

Question 4

Can it be used during a gasoline delivery?

Accepted Answer

Yes. The meter is intrinsically safe (ATEX and China National Ex certified) and runs on its own Ex battery, with no external power needed in the hazardous area.

Question 5

Is the meter calibrated?

Accepted Answer

Each meter is factory-calibrated and ships with a calibration certificate. Production runs under an ISO 9001:2015 quality system. Meter coefficients can be reviewed and adjusted through the Bluetooth app by authorized users.

Question 6

Can the delivery records be exported or audited later?

Accepted Answer

The meter stores 1,000 measurement records. Records can be queried on the meter or read out to an Android phone over Bluetooth, so individual deliveries can be reviewed after the fact.

Question 7

What's the difference between this and a clamp-on ultrasonic flow meter?

Accepted Answer

A portable ultrasonic meter clamps on the outside of a pipe and is convenient for surveys, but delivery verification needs higher accuracy and repeatability than clamp-on measurement can give. This turbine meter is in-line, reads to ±0.1% with ±0.02% repeatability, and adds automatic temperature compensation — the figures a delivery dispute actually turns on.
