Solution needed for counting pulse inputs WITHOUT using Intterupts

This earlier posting by jball is relevant Using an interrupt and LoRaWAN - Programming Questions - Arduino Forum

After trying to count pulses on a flow meter with sub optimal code he has now decided to abandon interrupt techniques.

interrupts();           // starts interupt
delay(1000);            //waits 1 sec
noInterrupts();         // ends interupt

Trying to use polling or external clock sources on timers would be a better tackled after standard pulse counting interrupt code was tried.

volatile unsigned long  count = 0;
unsigned long copyCount = 0;

unsigned long lastRead = 0;
unsigned long interval = 1000;//one second

void setup()
{
  Serial.begin(115200);
  Serial.println("start...");
  
  pinMode(2,INPUT_PULLUP);
  attachInterrupt(0, isrCount, RISING); //interrupt signal to pin 2
}

void loop()
{
  if (millis() - lastRead >= interval) //read interrupt count every second
  {
    lastRead  += interval;
    // disable interrupts,make copy of count,reenable interrupts
    noInterrupts();
    copyCount = count;
    count = 0;
    interrupts();
 
    Serial.println(copyCount);

  }
}

void isrCount()
{
  count++;
}
