How can i have several volume or flow rate variables ?

[kaertblan]

My project is to make a flowmeter with different sessions (with a selector to measure the water consumption of different people). I measure the flow of a session and I can switch to another. So I need to have several volume or flow variables! Example volume 1, volume 2 etc.... (with the pulse counter reset to zero each time I change session) Do you know how to do this? Thanks a lot ;)

maybe you can use array to save session volume and you can use Sensor.resetVolume() to set volume to 0, use interrupt to trigger session start and finish.

unsigned long volume[10];
uint8_t session;
bool sessionTrig = false;

void interruptFunc()
{
	if (sessionTrig != true)
		sessionTrig = true;
	else
	{
		session++;
		sessionTrig = false;
	}
}

void loop ()
{
	// use interrupt to trig session
	if (sessionTrig == true)
	{
  		if (millis() - timebefore >= 1000)
  		{
	  		Sensor.read();
			volume[session] = Sensor.getVolume();
	  		Serial.print("Volume (L) : ");
	  		Serial.println(volume[session]);
	  		timebefore = millis();
  		}
	}
}

thanks for your fast reply i think that can be works ! Only the session system works like that if (select_1 == 3) { // If select_1= 3 vol4 = 0.00225 * pulse_freq;

And I don't want to reset the volume because I want to keep seeing it but have multiple volume sessions. For example volume1 = Sensor.getVolume1(); volume2 = Sensor.getVolume2(); volume3 = Sensor.getVolume3(); That is, to have the same commands you've created, but specified per session ( Sensor.getFlowRate1_m()); Sensor.resetVolume1(); Sensor.resetVolume3(); etc....) Thank you
