Considerations for amplifying an ultrasonic echo

Hi, I'm designing an ultrasonic flow meter. I've got a problem that after I amplified a signal (waveform like below) with 200-500KHz frequency, Vpp (peak to peak voltage) 50mV to 1V, the jitter of TOF(Time of flight) cannot meet my requirements. I'd appreciate if anyone could give me some advice on how to do this. The TOF is about 200us and the jitter should be below 200ps.
