Description
Overview
GAOTek IoT ultrasonic gas meter is a new type of all electronic metering combustion which uses the time difference of ultrasonic transmission in the medium to measure Gas meter, with high reliability, high precision, temperature and pressure compensation and other endogenous functions. Time difference method is adopted in ultrasonic measurement, and its working principle is to use a pair of ultrasonic transducers to alternate in phase (or at the same time) send and receive ultrasonic wave, and indirectly measure the fluid by observing the time difference between forward and reverse flow propagation of ultrasonic wave in the medium Flow rate, and then through the flow rate to calculate the flow rate of an indirect measurement method.
