Abstract

See full text

A device for monitoring a mass or volume flow, in a gas stream with a feed line and with a plurality of electrical components, includes a flow generator, a heat-sensitive element and a data processing unit. The flow generator generates a gas stream flowing in a direction of flow through the feed line. At least one of the electrical components comprises at least one electrical element for power data supply, which is arranged in the feed line such that a waste heat of the electrical element heats the gas stream generated by the flow generator. The heat-sensitive element is arranged behind the electrical element in the direction of flow in the feed line and detects a temperature of the gas stream heated by the waste heat of the electrical element. The data processing unit determines a mass or volume flow from the temperature detected by the heat-sensitive element.
