The rationality of the selection of digital vortex flowmeters directly determines the adaptability of flow measurement and the reliability of data.
Many flow measurement deviation problems in industrial sites are not due to the performance of the instrument itself, but rather to the mismatch between the early selection and on-site working conditions. To select a digital vortex flowmeter that meets on-site needs, the core is to focus on these key parameters and avoid misunderstandings in selection.
First, it is necessary to clarify the properties of the measured medium. Digital vortex flowmeters can be adapted to various media such as steam, gas, and low-viscosity liquids, but different media have significant differences in their requirements for the structure and material of the instrument. For example, when measuring high-temperature superheated steam, a sensor material that is resistant to high temperature and pressure is required; when measuring corrosive media, a meter body made of corresponding anti-corrosion material is needed. These need to be clearly specified before selection.
Second, confirm the on-site working condition range. This includes the normal operating temperature, operating pressure of the medium, and the ranges of minimum flow, common flow, and maximum flow. During selection, it is necessary to ensure that the common on-site flow falls within the range ratio of the instrument to avoid problems such as inability to measure small flows and exceeding the range for large flows. At the same time, the instrument of corresponding specifications should be matched according to the on-site pipe diameter. If diameter reduction installation is required, parameter adaptation should be done in advance.
In addition, attention should be paid to the functions and output requirements of the instrument. For example, whether on-site display is needed, whether remote signal output is required, and whether supporting temperature and pressure compensation functions are necessary. These should be selected based on the on-site control system and data collection needs.
