Abstract: huaian ruentex group rotameter scale how to install the information produced by excellent
flow meter, flow meter manufacturer to offer you the quotation.
Single-phase liquid or gas flow meter main measurement object is, the solid particles in the liquid or gas containing droplets usually do not apply.
Because the float attached to particles in the liquid flow or tiny bubbles will affect the measurements.
If need to make a total far out signal transmission.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is huaian ruentex group rotameter scale details how to install the article.
Single-phase liquid or gas flow meter main measurement object is, the solid particles in the liquid or gas containing droplets usually do not apply.
Because the float attached to particles in the liquid flow or tiny bubbles will affect the measurements.
If need far transmission signal for integrating total or flow control, electrical signal output is generally selected tube rotor flow meter (
The metal flow meter)
。
Such as the environmental atmosphere with explosion-proof requirements and field control instrument air supply, give priority to the far eastone metal rotameter, if choose electric remote meter must be explosion-proof type.
Measuring temperature is higher than the ambient temperature of high viscosity fluid and easy to cooling crystallization precipitation or easy to solidification of liquid, should choose jacketed metal tube rotor flow meter.
Rotameter installed note: 1, the instrument must be vertical direction most of the rotameter installed on no vibration of the pipeline installation, should not have obvious tilt, fluid flow through the instrument from bottom to top.
The center line of the rotameter and the plumb line, generally no more than 5 degree Angle between the high accuracy (
1.
Level 5 or above)
Instrument & theta;
≤
20°
。
If & theta;
= 12度;
Will generate additional error 1%.
Instrument no strict length of straight pipe upstream requirements, but also have manufacturing requirements (
2 -
5)
D the length of necessity is not, in fact.
2, used in the installation of the dirty fluid should be in the upstream filter instrument.
With magnetic coupling tube rotor flow meter used in sexual impurity fluid may contain magnet, magnetic filters should be installed in front of the instrument.
To maintain the cleanness of float and cone tube, especially the small instrument, float clean degree significantly affect the measured values.
3, the installation of the pulsating flow rotor
flowmeter the pulsation of the flow itself, such as plans to install instrument position reciprocating pump or upstream of the regulator, or downstream has large load change, should be remedial change measuring position or in the pipeline system improvement, such as buffer tank;
Oscillations if the instrument itself, such as when measuring the gas pressure is too low, upstream of the valve is not fully open, downstream of the regulator is not installed in instrument such as reason, should be targeted to improve overcome, or re-election with damping device instrument.
4, rotor flowmeter flow value should make necessary conversion without according to the use of the density, viscosity and other medium parameters to the rotor flow meter manufacturer specially instrument, liquid instrument calibration flow with water, often gas meter calibration with air, fixed value in engineering standard state.
Conditions of use of fluid density, gas pressure, temperature and calibration are inconsistent, to do the necessary conversion.
Conversion formula and method of rotor flowmeter factory have a detailed instruction manual.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
