SENSOR_ORIFICE_PLATE.ino

C/C++
This code show you the pression and temperature values. Then with excel, you can compute the flow through the Numerical analysis.
#include <MemoryFree.h>

#include "max6675.h"

  //variables initialization
float Vs = 5.1;


float T_1=0;

  // START Thermocouple
int thermo1DO = 3;
int thermo1CS = 4;
int thermo1CLK = 2;
MAX6675 ktc1(thermo1CLK, thermo1CS, thermo1DO);

// START MPX5050
int PIN_P1 = A0;        
float Analog_P1 = 0;
float Vout_P1 = 0;
int P_1 = 0;

//SETUP

void setup() { 
  Serial.begin(9600);      // START serial communication

}

  // LOOP
void loop() {

  // read the thermocouple
T_1 = ktc1.readCelsius();


// read the pressure sensor
Analog_P1 = analogRead(PIN_P1);
Vout_P1 = ((Analog_P1 * 0.00369) + 0.04);
P_1 = (Vs * Vout_P1);
delay(1000);


  // print data
 Serial.print("T=");
 Serial.print(T_1);
 Serial.print("C");
 Serial.print("\n");
 Serial.print("P = ");
 Serial.print(P_1,1); 
 Serial.print("Kpa");
Serial.print("\n");
}
