Frequently Asked Questions about Fuel Flow Meters

The Coriolis flow meter FZ series has a proven track record of measuring urea water. We believe that those who understand the characteristics of urea water will be able to use it.
Urea water forms crystals when exposed to air, and these crystals accumulate in the joint parts and inside the flow measurement tube. Since the accumulated crystals can affect measurement errors, it seems possible to use the device if the conditions are met to wash away these crystals by flowing water or similar substances.
However, please note that the calibration fluids used in Ono Sokki's calibration equipment are industrial gasoline or diesel. We can only provide detectors calibrated with these test fluids.

* The flow range, operating temperature range, and usage conditions are important points to confirm. Additionally, measurements cannot be taken in vehicles due to fluctuations caused by vibrations.
