Embodiment Construction
[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0041] Such as figure 1 As shown, a high-accuracy steam flow measurement method based on wireless transmission, which uses a high-accuracy steam flow measurement system based on wireless transmission, it includes the following steps:
[0042] S1. Install the vortex flowmeter, pressure sensor, and temperature sensor on the pipeline to be measured in sequence, respectively obtain the output frequency of the vortex flowmeter, the instantaneous steam pressure value and temperature value and send them to the wireless data acquisition module;
[0043] S2. After receiving the above data, the wireless data acquisition module sends it to the terminal data analysis and processing unit through the communication network;
[0044]S3. In the terminal data analysis and processing unit, first correct the instantaneous steam pressure value and temperature value sent by...

The invention discloses a high-accuracy steam flow metering system based on wireless transmission and a method thereof. The system comprises a vortex street flowmeter, a pressure sensor, a temperature sensor, an automatic wireless transmission data collection system and a terminal data analyzing and processing system. Through the system and the method, the steam under different temperatures and pressure conditions can be accurately metered; corrected values are input into a computation system and a steam density computation mathematical model, so that the metering accuracy can be further improved; wireless transmission and networking can be carried out; the data can be further used and shared; the high-level management requirements of heat supply enterprises and heat consumption enterprises can be met.
Description
technical field [0001] The invention relates to a high-accuracy steam flow metering system based on wireless transmission. The metering system can meet the national mandatory standard GB17167-2006 "General Rules for the Equipping and Management of Energy Measuring Instruments for Energy-Using Units" and the administrative department of metering for commercial metering. The requirements for the accuracy of the appliances and the fairness and justice of the transfer of trade between the relevant heat supply and use enterprises. Background technique [0002] At present, the traditional steam flow metering system consisting of four parts of vortex flowmeter, pressure sensor, temperature sensor and flow totalizer has been widely used, and the existing problems mainly include: [0003] 1. The composite accuracy of the system is determined by the accuracy of the four components, which cannot be modified and improved, improperly selected, or even unable to meet the requirements of n...
