Frequently Asked Questions about Fuel Flow Meters

"LEVEL ERROR" lights up when the fuel level in the FX series detection unit reaches the lower limit (indicating fuel depletion) or the upper limit (indicating overflow). This occurs when the fuel consumption of the test specimen is high, leading to insufficient fuel supply to the FX, or when the consumption flow rate of the test specimen is low, resulting in excessive supply to the FX. Please check if fuel is being supplied properly.

If 'LEVEL ERROR' is constantly displayed, there may be fuel accumulated in the reference tube. Please refer to the manual, open the cover, and try draining the fuel from the reference tube.
