The use conditions and installation requirements of the Integrated orifice flowmeter
Release time：2017-09-29 Clicks：792
1, fluid conditions:
A, the fluid must be filled and continuously flow through the measuring section of the pipeline
B, the fluid should be uniform, single phase or can be considered a single phase
C, the fluid flow through the orifice, no phase change
D, before the fluid flows through the orifice, the flow rate must be parallel to the pipe axis, no rotary or pulsating flow
2, pipeline conditions:
A, measuring section of the pipeline must be straight, cross-section circular pipe, pipe wall should be smooth and smooth, no sediment;
B, the installation of the flow meter measuring pipe section does not allow vibration phenomenon, the vibration will interfere with the output signal
3, installation, use requirements:
A, the flowmeter can be installed in the horizontal or vertical pipe, the installation must pay attention to the flow direction and flow meter arrows marked the same direction
B, measuring all the gasket in the pipe section, after clamping should not penetrate the pipe, otherwise it will make the flow rate disorder, the impact of measurement accuracy
C, before and after the flowmeter should have long enough straight pipe
D, in the installation of flowmeter in the pipeline, do not produce excessive water hammer impact, so as to avoid damage to the flow meter
E, the flowmeter should not be installed in the pipeline with two-position switch valve, the valve on and off the impact of the impact, and sometimes damage the flow meter
F, in the new laying of the pipeline to install the flow meter, should be installed in the water after cleaning the pipeline. If you first install the flow meter, and then water injection pipeline, due to water pressure and dirty impurities and other factors easy to make the flow meter failure or even damage.
4, environmental requirements:
The integrated standard orifice flowmeter should not be installed in the following environments:
A, high temperature (> 60 degrees Celsius) environment
B, heating and other heat sources nearby
C, direct sunlight
D, where the humidity is too high
E, rain or water
F, vibrating and dusty place
If you can not avoid, you should take appropriate protective measures
5, antifreeze and moisturizing measures:
In cold areas, when the flow meter installed in the outdoors, in order to prevent the pressure tube to freeze, must take measures to prevent moisture.
Antifreeze insulation measures may have:
A, with the incubator to protect the flow meter, which is easy and good measures.
B, you can also use insulation material banding method to achieve the purpose of insulation.
