One of our 34SG engine’s gas ramp fuel gas cumulative mass flow totalizer is malfunctioning. When it is started for the day, the totalizer on the WISE displays the reading from the end of previous run. When the engine is started it resets down to the total lbs burnt on that particular day. The totalizer on the WOIS is about 4243 lbs higher than the WISE. There is only 1038 hours of operation on the engine. Anyone run into this problem?
