@speed57 like this, see first 2 lines of the timed function:

  void PowerMeter() 
{
  int vt_read = analogRead(VT_PIN);
  float voltage = vt_read * (3.2 / 1024.0) * 5.0;  
  Blynk.virtualWrite(V1, voltage);
  terminal.println("Volts: "); 
  terminal.flush();
  terminal.println(voltage, 3);
  terminal.flush();
  Serial.print("Volts: "); 
  Serial.print(voltage, 3);  
}
