Abstract

The invention discloses an ultrasonic mass flowmeter. The ultrasonic mass flowmeter comprises a liquid flowing pipe, at least one group of ultrasonic sensors arranged on the pipe, and a measurement host, wherein the measurement host controls the ultrasonic sensors to transmit and receive signals to obtain mass and flow values; the ultrasonic sensors are composed of ultrasonic transmitters and ultrasonic receivers, which are on the upper side and the lower side of the pipe respectively and located inside a plane passing through the axis of the pipe. According to the ultrasonic mass flowmeter, with the high-frequency characteristics, ultrasonic waves can complete high-precision measurement and are high in mass and flow measurement precision. The ultrasonic mass flowmeter is simple in device structure, namely, is composed of the sensors and the host without complicated mechanical parts. Meanwhile, the ultrasonic mass flowmeter is applicable to mass and flow measurement of various kinds of fluid, thereby being diversified in measured objects. Also, the ultrasonic mass flowmeter can achieve comprehensive analysis of various parameters of fluid to be measurement and can measure the information of mass, flow, density, temperature, energy and the like simultaneously.

Description

technical field

[0001] The invention relates to the technical field of flowmeters, in particular to an ultrasonic mass flowmeter. Background technique

[0002] At present, there are many mass measurement methods, such as: Coriolis mass flowmeter, differential pressure mass flowmeter, combined flow measurement, etc.

[0003] However, the existing relevant measuring instruments have the following defects: 1. The measurement accuracy is uneven; 2. The adaptability of the instruments is poor. Some measuring instruments can only measure fixed fluids. For example, they can only measure gases and cannot adapt to a variety of fluids; The accuracy is low, and it is difficult to unify the two.

[0004] More importantly, none of the above instruments can comprehensively measure the physical parameters of the fluid to be measured. For example, the flow meter only measures the flow rate, and the density meter only measures the density. To sum up, the existing fluid physical parameter ...
