摘要: A method includes receiving a gas or gas mixture through a flow sensor. A flow velocity, volumetric, or mass flow are determined. The method also includes determining a sound velocity of the gas or gas mixture by an ultrasonic sensor. A density of the gas or gas mixture is correlated from the sound velocity. The method also includes positioning a microthermal sensor in an area with less flow or no flow of the gas or gas mixture. A thermal conductivity and thermal diffusivity of the gas or gas mixture at the one or more temperatures is determined. The method also includes connecting a processor to the microthermal sensor to calculate an energy of the gas or gas mixture based on a calorific value, the temperature and the volume or mass flow. Specific quantities for gas quality are correlated.

摘要: A system includes a flow tube configured to receive a flow measured by an ultrasonic flow measurement, wherein a center region of the flow tube is configured to have a drop in pressure. The system also includes a heat source/hot wire and temperature sensors configured to enable a flow measured by a thermal massflow measurement. In the system, a controller is configured to compare the flow measured by the ultrasonic flow measurement to the flow measured by the thermal massflow measurement. The controller determines a ratio of the flow measured by an ultrasonic flow measurement to the flow measured on by the flow measurement based on thermal massflow. The controller also calculates a density, a thermal conductivity and an energy and / or gas content of the gas.

摘要: A valve without position indicating switches. Positions of the valve are detected from current magnitude measurements and current profile analytics. The current profile may be learned initially and relearned and adapted at each operation. The valve may be opened and closed by a driver that is actuated byan electrical current to control the opening and closing of the valve. The current may be regulated by a controller to open and close the valve appropriately.
