초록 ▼

An ultrasonic gas measuring device including a housing, end walls for the housing, the end walls having a gas inlet and a gas outlet provided therethrough, ultrasonic detecting means provided within the housing means, the ultrasonic means having a transmitter, operatively mounted on one end wall, and a receiver, operatively mounted on the other end wall, arranged at spaced locations within the housing, the housing incorporating gas processing means for dividing the gas flow at least at some instance during its flow through the housing, electronic circuitry functioning to detect and generate a signal in cooperation with the ultrasonic detecting means representative of the concentration of gas passing through the housing, the electronic means also generating a reference signal corresponding to the electronic signal delivered to the ultrasonic means, a phase shift provided within the electronic circuitry and effecting a shift of one of said signals to furnish an aligned phased relationship between the two signals whereby the concentration of the gas passing through the housing as detected by the ultrasonic means can be electronically computed and precisely determined by the said electronic means.

대표청구항 ▼

An ultrasonic gas measuring device for continuously monitoring the gas including a housing means, said housing means having a gas inlet and a gas outlet provided therethrough for passage of a gas to be measured, ultrasonic means provided within the housing means, said ultrasonic means having a transmitter and a receiver disposed at spaced locations at opposite positions of the housing means for transmission of its ultrasonic waves along the length of the passing gas, electronic means operatively associated with the housing means to measure the concentration of gas flowing therethrough, said electronic means including a receive amplifier which functions to detect and generate in cooperation with the ultrasonic means a signal corresponding to a concentration of a gas passing through and along the length of the housing means, said electronic means also including an oscillator and driver and generating a reference signal corresponding to the electronic signal delivered to the ultrasonic means, and electronic phase shift means electrically connected with the receive amplifier and effecting a shift of the first said generated signal to furnish a phased relationship between the generated signal and the reference signal, and signal conditioner means providing for revision of the generated signal due to one of temperature, pressure, and humidity compensation, wherein a larger span for comparison between the reference signal and the signal corresponding to the concentration of the gas provides greater accuracy in the measurement of the percentage of concentration of the passing gas.
