Compressed air
flowmeter twelve basic principles that should pay attention to the installation requirements: be installed compressed air flow meter measuring inner diameter and pipe diameter of the pipe should be consistent.
Elected to use compressed air flow meter measuring inner diameter less than or greater than the process pipe diameter of the tube, need reducing.

Compressed air flowmeter twelve basic principles that should pay attention to the installation requirements: be installed compressed air flow meter measuring inner diameter and pipe diameter of the pipe should be consistent.
Elected to use compressed air flow meter measuring inner diameter less than or greater than the process piping of the pipe diameter, need reducer connection at both ends, to ensure that the inner diameter is consistent, and ensure the straight pipe requirements.
* point, the principle of consistent basis.
Be installed compressed air flow meter measuring pipe diameter and pipe diameter should be consistent.
Elected to use compressed air flow meter measuring inner diameter less than or greater than the process piping of the pipe diameter, need reducer connection at both ends, to ensure that the inner diameter is consistent, and ensure the straight pipe requirements.
The second principle, easy to maintenance.
Should be installed to facilitate maintenance, when necessary, should add maintenance platform.
Third, the principle of lower and weaken the external disturbance.
Should be installed in the location of the less susceptible to external disturbance, as far as possible, for example, should be far away from the vibration source, not installed in the compressor room and other places;
Away from the electromagnetic disturbance source, for example, not to install near the frequency converter, etc.
In addition, should be accurate and reliable grounding.
Fourth, the principle of full pipe flow.
In addition to the open channel flow meter, install the flow time should ensure that the fluid can full pipe flow.
When necessary, can reduce installation height, make the pipe flowmeter measurement below the process piping, to achieve full pipe flow requirements.
Some occasions, can change the flow from top to bottom to flow from bottom to top, ensure full pipe flow requirements.
Fifth, the principle of emissions.
Liquid fluid may be entrained gas or liquid, gas fluid may be condensed liquid or liquid entrainment, they will make the flow cross-sectional area change, therefore, in the process piping installation flowmeter zui low position should be set drainage device, the exhaust zui high position, to facilitate drainage and exhaust.
Sixth, the principle of washing.
For easy crystallization and precipitation or smudgy fluid should be set flush line, easy to guide tube and testing parts for cleaning.
The first, prevent excessive stress principle at seven o 'clock.
Flowmeter measurement tube flange and adjacent process between the tube into the flange connection, should prevent excessive stress, due to the impact on the flow meter.
For example, damages to the electromagnetic flowmeter lining.
For connecting bolts should be uniform stress, and ensure the seal.
The first, the principle of axis is consistent at 8 o 'clock.
Flowmeter measurement tube and the axis of the process piping should be consistent, right on the axis of the process piping, it is necessary to ensure alignment.
First, the principle of fully developed flow at nine o 'clock.
In order to ensure the fluid flow was fully developed flow, should guarantee a prescribed length of straight pipe upstream or downstream, conform to the requirements of the specified pipe roughness, flow regulator shall be installed where necessary.
The first ten, the principle of reducing resistance.
Minimize the number of pipe installation, as far as possible with low flow resistance of the connection pipe fittings.
For example, in the same plane of two 90 & deg;
Can bend into two 45 & deg;
Elbow, etc.
The first eleven o 'clock, the principle of control valve installation.
Used to adjust the flow control valve should be installed in the downstream of the flow meter, and meet the requirements of the downstream straight pipe length.
The first twelve o 'clock, cleaning, welding principle.
The meter shall be installed after the process piping cleaning.
Flange welding process, the length of pipe with such as alternative.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
