摘要： The invention relates to an arrangement in connection with a gas mixer, which is arranged to form a mixed gas of oxygen and another gas to be mixed with it. To provide a simple and reliable arrangement, before the mixed gas is formed the oxygen is arranged to be supplied through both a mechanical adjusting means (4), and a mechanical and electronic flow-measuring means (5, 6). The other gas to be mixed with oxygen is arranged to flow through an electronic flow-measuring device (10). The flow of the other gas is arranged to be regulated by means of an electronically controlled regulating valve (9), whereupon the electronic flow-measuring means (6), the electronic flow-measuring device (10), and the electronically controlled regulating valve (9) are arranged to be operated by means of a control unit (13).
