The AVI-GAS AUTO gas meter is a stationary device intended for monitoring the composition of the atmosphere in fruit and vegetable storage facilities. It was designed to eliminate the inconvenience of daily measurements and manual oxygen admission.

Blowers installed on valves make it possible to automatically regulate the oxygen level. The device also signals when the carbon dioxide level is exceeded and when the amount of lime in the chamber should be increased.

The gas sampling system is monitored by a flow sensor. If the flow is too low, for example due to a clogged or frozen measuring hose or pump failure, an alarm is activated.

A touch panel integrated with the LCD display makes operation simple. To make the device status easy to interpret, it is equipped with two LEDs visible from a long distance, allowing even uninvolved persons to see whether the device is operating correctly.
