Abstract

The invention relates to an ultrasonic flowmeter with pipe detection and self-correction functions. The ultrasonic flowmeter comprises a control circuit, a temperature sensor, a pressure sensor and two sets of ultrasonic energy converters, the temperature sensor, the pressure sensor and the ultrasonic energy converters are all connected with the control circuit through electrode leads, a first set of the ultrasonic energy converters comprises a first emitting probe and a first receiving probe, a second set of the ultrasonic energy converters comprises a second emitting probe and a second receiving probe, the first emitting probe and the first receiving probe are arranged on a gas pipeline in a 45-degree-inclination manner, the second emitting probe and the second receiving probe are arranged on the gas pipeline in a 45-degree-inclination manner, and the control circuit comprises a waveform and clock signal generation circuit, a pre-amplification circuit, an envelope detection circuit and a CPU (central processing unit) processing circuit which are electrically connected with one another. Accuracy of ultrasonic flowing-speed measuring can reach 10-5-10-6 orders of magnitude; pulse measuring which is higher in collection frequency is adopted, so that the ultrasonic flowmeter is higher in accuracy rate.

Description

technical field [0001] The utility model relates to a gas ultrasonic flowmeter, in particular to an ultrasonic flowmeter with pipeline detection and self-correction, which belongs to the technical field of automatic instruments. Background technique [0002] With the rapid development of automatic flow measuring instruments, especially ultrasonic flow measuring technology, people pay more attention to find new flow measurement technology. The development of ultrasonic flow measurement in recent years is changing with each passing day. Compared with traditional flow meters, people are looking for flow meter measurement methods with higher benefits, longer life and higher reliability. [0003] Ultrasonic flow meters are rapidly developing into the field of flow measurement, especially the first choice for metering hydrocarbons. As users gradually realize the many advantages of ultrasonic flow meters, including high accuracy, unobstructed measurement and low total cost of...
