Selection elements and installation conditions of glass rotor flowmeter

With the development of society, industry, and flow meters, with different requirements for measurement nowadays, flow meters have also become more diversified, with an increasing number of types and models. At present, each type of flowmeter has its own advantages and limitations, and no flowmeter can be used in any situation, measure any medium, and so on. But sometimes for some media, they can all be used, such as measuring media like water. Glass rotor flowmeter, electromagnetic flowmeter, vortex flowmeter, etc. can all be used. So which one is more suitable? Factors such as installation conditions, environmental requirements, and flow meter performance all become factors in selecting a suitable flow meter. The selection of flow meters is to choose the most suitable type of flow meter, highlight the advantages of different flow meters, and make the flow meter play the greatest role and effect.
In terms of price, glass rotor flow meters are definitely more economical, but they cannot be compared with electromagnetic flow meters in terms of pressure resistance and accuracy. So, what aspects should be considered when selecting a flowmeter?
Generally, the selection of flow meters can be considered from five aspects: instrument performance, fluid characteristics, installation conditions, environmental conditions, and economic factors.
1. In terms of instrument performance:
The primary consideration when buying a flowmeter is its performance, including accuracy, repeatability, linearity, range, flow range, signal output characteristics, response time, pressure loss, etc;
2. In terms of fluid characteristics:
Temperature, pressure, density, viscosity, chemical corrosion, abrasion, scaling, phase mixing, phase change, conductivity and other indices. Like electromagnetic flow meters, electromagnetic flow meters can only measure liquids and are conductive liquids.
3. In terms of installation conditions:
Pipeline layout direction, flow direction, length of straight pipe sections upstream and downstream of the detection component, pipeline diameter, maintenance space, power supply, grounding, auxiliary equipment (filters, air purifiers), installation, etc;
4. In terms of environmental conditions:
Environmental temperature, humidity, electromagnetic interference, safety, explosion-proof, pipeline vibration, etc;
5. In terms of economic factors:
Instrument purchase cost, installation cost, operation cost, calibration cost, maintenance cost, instrument service life, spare parts, etc.
