The precession vortex flowmeter is a new type of gas flow instrument that adopts micro processing technology and has advantages such as strong functionality, wide flow range, simple operation and maintenance, and convenient installation and use. Its main technical indicators reach the level of similar foreign products.
No mechanical movable parts, corrosion resistant, stable and reliable, long service life, long-term operation without special maintenance;
Realized mechatronics integration, eliminating the need for manual attendance in daily measurement processes;
The process installation conditions are not strict, and the upstream and downstream straight pipe sections of the instrument can be greatly shortened compared to orifice plates and vortex flowmeters;
The measurement accuracy of the system can meet the current trade measurement requirements (≤ 1.5%);
The flow measurement range is relatively wide (qmax/qmin=15-20), which can effectively work in small flow areas that cannot be accessed by orifice and vortex flowmeters;
Small size, light weight, and convenient offline calibration;
The measurement signal can be displayed locally or transmitted remotely as needed;
Instrument management personnel do not need training, and measurement parameters such as flow, pressure, and temperature can be directly read from the meter head without the need for conversion;
Just regularly replace the battery (micro power consumption) and the parameters of the tested medium;
Large pressure loss: When the flow medium is gas, the pressure loss is about 3-4 times that of the vortex flowmeter.
