In cruise flight at FL350 we lost fuel quantity indications on the left; center; and total fuel quantities. We also received an AUTO XFLOWINHIBIT message. The fuel synoptic page also indicated an AUTO XFLOW INHIBIT message and showed amber dashed lines for the left; center; and total quantities and approximately 1;700 LBS of fuel in the right wing tank. We tried to get Maintenance Control through the company frequency and could not. We [contacted] Dispatch [via] ACARS that we were going to divert and stated the fuel conditions along with out estimate of FOB. We received an ACARS from the Dispatch saying to continue to [destination] and call when we got there.We referenced the QRH and there is no procedure for no quantity (amber dashed lines) indication. We decided that not knowing the true fuel quantity and the possibility that we were creating a fuel imbalance that could exceed the 800 LBS limitation; and that the current indicated fuel onboard was within 200 LBS of our reserve fuel that the best idea was to divert to [a nearby airport]. We then declared an emergency with ATC and were vectored to the ILS; accomplishing a normal approach and landing below maximum landing weight. After arrival Maintenance Control MEL'd the quantity indicators; refueled the aircraft per the MEL and we continued to [original destination]. I feel we handled this situation well as a crew to best serve the needs of safety; our passengers; and the company.
CRJ-200 First Officer reported loss of all fuel quantity indicators. They elected to divert to a nearby airport even as Dispatch recommended continuing to destination.
