  • Method and sensor for measuring a mass flow
    Patent number: 6550324
    Abstract: A heating element (4) is arranged between two temperature sensors (5, 6) in order to measure the mass flow of a liquid or a gas. The mass flow is determined from the temperature difference of the temperature sensors (5, 6). The heating element (4) is operated by pulses in order to reduce power consumption of the device. A further reduction of the power consumption is reached by means of a monitoring circuit (12), which switches the actual measuring section (11) on only if the signals from the temperature sensors (5, 6) fulfil a threshold condition.
