Embodiment Construction

[0074] Ultrasonic flow meters have the advantages of high precision, good reliability, and no moving parts, and can widely replace traditional mechanical fluid measuring meters. Most of the ultrasonic flowmeters in the prior art include TDC and transducers. During the working process of the ultrasonic flowmeter, the TDC obtains the time difference between the forward propagation time of the ultrasonic wave and the upstream propagation time of the ultrasonic wave according to the reference clock, and then converts the time difference into the time difference of the delay unit. The number of stages, so that the measurement control obtains the flow rate of the fluid according to the time difference.

[0075] If the time difference measured by the TDC is larger, that is, the longer the TDC works, the more delay units the measured signal passes through, and noise will inevitably be introduced during this process, and the accumulation of noise will be related to the delay proportion...

Abstract

The invention provides a fluid flow measuring system which comprises a signal generating unit, a first signal processing unit, a second signal processing unit and a first time-digital converter (TDC).One end of the first TDC is connected with the signal generating unit, and the other end of the first TDC is connected with one end of the first signal processing unit and one end of the second signal processing unit. The other end of the first signal processing unit is connected with the signal generating unit. The other end of the second signal processing unit is connected with the signal generating unit. The signal generating unit generates a first back wave and a second back wave, and the first back wave and the second back wave are sent to the second signal processing unit and the firstsignal processing unit respectively. According to the system, the flow measuring accuracy of the system can be effectively improved.

Description

technical field [0001] The invention relates to flow measurement technology, in particular to a fluid flow measurement system. Background technique [0002] Ultrasonic flow meter is a kind of measuring instrument that calculates the flow rate of fluid by measuring the time difference between forward flow and reverse flow of ultrasonic waves in fluid. [0003] TDC is the core device in the existing ultrasonic flow meter. The basic principle of TDC is to convert the time difference into the series of delay units, and then obtain the time of ultrasonic wave forward and backward propagation, and calculate the flow rate of the fluid. [0004] If the time difference measured by the TDC is larger, that is, the longer the TDC works, the more delay units the measured signal passes through, and noise will inevitably be introduced during this process, and the accumulation of noise will be related to the delay proportional to the number of units. Therefore, the longer the TDC works, t...
