I tested it, but not with the gas meter, but with a magnet. It worked. The code below:

esp32:
  board: nodemcu-32s
  framework:
    type: arduino

sensor:
  - platform: pulse_counter
    pin: 
      number: GPIO1
      mode: INPUT_PULLUP
    unit_of_measurement: 'pulse/min'
    device_class: "gas"
    state_class: "measurement"
    icon: mdi:meter-gas
    update_interval: 10s
    accuracy_decimals: 2
    name: 'gas (fordulat)'
    use_pcnt: false
    internal_filter: 0.3s
    id: gas_fordulat
         
    total:
      accuracy_decimals: 2
      unit_of_measurement: 'm³'
      device_class: "gas"
      icon: mdi:meter-gas-outline
      state_class: total_increasing
      name: 'gas teljes'
      filters:
        - multiply: 0.01  # (0.01 m3/ turn)    

  - platform: uptime
    name: Uptime GAS Sensor
  
  - platform: wifi_signal
    name: "WiFi Signal GAS Sensor"
    update_interval: 60s

I put it in place and incorrect measurements are also received.
I tried to set the internal_filter with not much result.

Does anyone have an idea?
