Abstract: the installation of metal tube float meter scale considerations information produced by excellent
flow meter, flow meter manufacturer to offer you the quotation.
The installation of metal tube float flowmeter note 1 meter before the process piping installation, should remove all installation and check if there is any transportation damage.
2 meter in transit to prevent, fixed pointer rubber bands, are installed in the indicator should open the indicator before wiring.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is the installation of metal tube float meter scale considerations article details.
The installation of metal tube float flowmeter note 1 meter before the process piping installation, should remove all installation and check if there is any transportation damage.
2 meter in transit to prevent, the indicator is equipped with a fixed pointer rubber bands, before connection should be put it gently remove indicator left open, don't pointer position change.
3 open the indicator right cover, cable through the cable device are introduced according to the rotation Angle transducer after wiring diagram wiring, screw the nut, the cable is fixed, then tighten the cover around the fastening screw, makes the indicator waterproof and dustproof.
4 meter of upstream and downstream piping should be the same as the instrument of caliber, connecting flange or thread should be with the instrument flange and match, the gauge length of straight pipe upstream should guarantee is 5 times of nominal diameter, h2 downstream straight pipe length of not less than 250 mm.
5 because of the instrument measuring mechanism is the magnetic transmission, so in order to guarantee the performance of the instrument, the installation of sensors around at least 100 mm, ferromagnetic materials are not allowed to exist.
6 meters before the installation, process piping should be purging, are attached to the instrument to prevent retention of ferromagnetic material in the pipeline, affect the performance of the instrument, even damage the instrument.
If unavoidable, should be installed at the entrance of instrument magnetic filter.
7 measuring gas meter, is under particular pressure calibration, if the export of gas in the instrument direct emissions to the atmosphere, will have the pressure drop in the float, and cause data distortion.
。
If this is the working condition, a valve should be installed at the export of instrument, so as to set the required flow rate value for.
When float on maintaining calibration pressure, gas puff in the valve.
8 instrument installation forms can be divided into vertical and horizontal installation, if it is a vertical installation form, should guarantee the instrument of straight degree is better than that of 1%;
If it is horizontal form should guarantee the levelness of the instrument is better than 1%.
9 install instruments should not be in the pipeline stress the role of the instrument's exports and entry should have the appropriate pipe supports, can make the instrument in the zui small stress state.
10 products that is associated with computer operation, calibration, as well as should be carried out in a safe place.
Special note: before installing the flowmeter to the stolen goods, within the pipeline welding according to the impurities such as blowing clean, if the solid impurities in the liquid, should be installed between the valve and the straight pipe corresponding filter.
Shielding and grounding: in order to ensure zui better emc performance of the system, shielding and grounding is very important, especially the bus cable.
To make the cable shielding as continuous as possible.
For safety, it is cable in accordance with the requirements for conventional ground as soon as possible.
In dangerous places, to ensure that within the scope of the whole bus safety and danger all enough potential, such as matching, in this case, the multiple ground is very superior.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
