Problems solved by technology
In practical applications, differential pressure flowmeter products such as orifice flowmeters still have some defects and deficiencies, for example, their overall structure is relatively complex, on-site installation operations are cumbersome, occupying a large space, and high manufacturing costs, etc.
In addition, for measurement occasions such as low pressure, low temperature, and relatively simple working conditions, it is very unsuitable to use existing flowmeters such as conventional split flowmeters.

The invention relates to an integrated differential pressure flowmeter and a measuring system including the same. The integrated differential pressure type flow meter comprises a body, the body is provided with a connecting part, an internal flow channel and at least two pressure tapping holes communicated with the internal flow channel, and the body is communicated with an external fluid source through the connecting part so as to introduce fluid to flow through the internal flow channel; the throttling element is arranged in the internal flow channel and is positioned between two adjacent pressure tapping holes so as to form fluid differential pressure between the two adjacent pressure tapping holes; the shell is connected with the body and is provided with a cavity; the at least two pressure leading pipes are arranged in the cavity, and one end of each pressure leading pipe is communicated with one of the pressure tapping holes; the sensor device is arranged in the cavity, is communicated with the other end of each pressure guide pipe and is used for detecting and acquiring at least one parameter data according to the fluid flowing into each pressure guide pipe; and the flow transmitter is connected with the shell and the sensor device and is used for calculating fluid flow data according to the parameter data. The method is suitable for large-scale popularization and application.
Description
technical field [0001] The invention relates to the technical field of flow measurement, in particular to an integrated differential pressure flowmeter and a measurement system including the integrated differential pressure flowmeter. Background technique [0002] At present, many types of differential pressure flowmeters have been provided in the field of flow measurement, and they have been widely used. For example, the orifice flowmeter is a commonly used flow measurement device, and its market application scale is already very large. Most of the commonly used orifice flowmeters are split structures, which are usually composed of orifice throttling pipes, differential pressure transmitters, flow totalizers, connected valve groups, pipe fittings and many other components. In practical applications, differential pressure flowmeter products such as orifice flowmeters still have some defects and shortcomings, such as their overall structure is relatively complex, on-site ins...
