Flowmeter is now an indispensable industrial measuring instruments, flowmeter selection as manufacturers and customers need to pay attention to the problem, the flow meter on the election, and more with less. The following by the Huaheng instrument to introduce you to flowmeter selection need to focus on what aspects:
The general principles of flowmeter selection: flowmeter performance requirements, fluid characteristics, installation requirements, environmental conditions, flow meter prices so several aspects to consider.
Fluid properties, that is to say the flow meter to measure the physical properties of the fluid, this aspect is the need to provide, this paper mainly talk about the flowmeter fluid parameters: medium corrosive medium temperature, medium viscosity, pulsation;
1. Medium Corrosion: According to whether the corrosive fluid, should pay attention to select the material flow meter.
2. Medium temperature: As the volume of fluid are generally change with the temperature changes, so the need for high-precision measurement must use temperature compensation device.
3. Medium viscosity: a variety of flowmeters are affected to varying degrees by the viscosity of the high viscosity fluid to pay special attention.
4. Pulsation: As the volume flowmeter is generally vulnerable to the impact of pulsation, so in the pipeline to consider reducing the pulse.
5. Foreign matter mixed with: filter with a foreign body can be removed, but if there is inevitably mixed with foreign matter, the use of volume flowmeter should pay special attention.
As far as possible to provide accurate fluid properties, installation environment, installation requirements, flow meter manufacturers to provide customers with the most appropriate flow meter
