Flowmeter selection main point
Choosing a suitable flowmeter is very important for energy saving and emission reduction and improving efficiency. Whether the flowmeter is selected correctly or not determines whether the instrument can be used normally or not.
There are many brands and manufacturers of flowmeters, and no flowmeter can be used universally. Different flowmeters have different characteristics. How to choose the most suitable flowmeter product among the many flowmeter varieties.
For example, in the selection of Fuji flowmeter, five aspects need to be paid attention to:
1. Measure the characteristics of fluids: fluid temperature, pressure, density, viscosity, chemical corrosion, abrasiveness, scaling, miscibility, phase transition, electrical conductivity, sound velocity, thermal conductivity, specific heat capacity, isentropic index;
2. Installation conditions of Fuji flowmeter: mainly include the direction of pipeline arrangement, the flow direction of the on-site display electromagnetic flowmeter, the length of the straight pipe section on the upstream and downstream sides of the detection piece, the diameter of the pipe, the maintenance space, power supply, grounding, auxiliary equipment (filter, getter device), installation, etc.;
3. Performance indicators of Fuji flowmeter: including the accuracy, repeatability, linearity, range, flow range, signal output characteristics, response time, pressure loss and other technical indicators of the flowmeter;
4. The environment of Fuji flowmeter: including ambient temperature, humidity, electromagnetic interference, safety, explosion-proof, pipeline vibration, etc.;
5. Economic factors: Fuji flowmeter purchase cost, installation cost, operation cost, calibration cost, maintenance cost, instrument service life, spare parts, etc.
