flow meter scale precision is how to guarantee?
Information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Company production of metal flow meter is a kind of variable area flowmeter, under a main scale upward vertical cone tube, the circular cross section of float is under the liquid force of gravity, can float freely in the cone tube rises and falls.
In the flow.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is how to ensure the accuracy of metal flow meter scale?
The article details.
Company production of metal flow meter is a kind of variable area flowmeter, under a main scale upward vertical cone tube, the circular cross section of float is under the liquid force of gravity, can float freely in the cone tube rises and falls.
Under the effect of flow velocity and buoyancy moves up and down, and the float weight balance, reached with the dial indicator flow through the magnetic coupling.
Metal flow meter is commonly used in industrial automation process control of a kind of flow measurement of appearance, it has a small pressure loss, large scale (
Range than 10:1)
, the use is convenient wait for a characteristic, it can be used to measure liquid, gas and steam flow, especially suitable for low velocity of small flow of medium flow measurement.
Metal flow meter precision is how to ensure that customers purchase?
Now tell us: 1, the metal flow meter device to prevent direct sunlight, high temperature environment (
≥
65℃)
To prevent the decline in the capacity of lithium-ion batteries and stature.
Appearance with lithium batteries.
In order to ensure the normal operation of metal rotameter and reach the demand of measurement accuracy, to try to prevent direct sunlight, high temperature equipment environment (
≥
65℃)
To prevent the decline in the capacity of lithium-ion batteries and stature.
Appearance with lithium batteries.
2, fluid flows through the flowmeter from bottom to top, straight metal rotameter necessary equipment.
And go straight to 2 & deg;
, equipment level is better than 2 & deg Angle;
To dispose of problems or blow does not affect yield;
Equipment in the technical line of metal tube float flowmeter should add bypass.
3, export should be 250 mm straight pipe, metal pipe flow meter at the entrance of straight pipe length should be more than 5 times the pipe diameter.
To ensure the appearance measurement accuracy;
4, equipment should be magnetic filter;
If it is a medium containing ferromagnetic material.
5, should think about between the straight pipe valves and filter;
If the medium containing solid impurities.
6, should ensure that pipeline pressure of not less than five times the flowmeter is missing, when used for gas measurement.
In order to make float safe operation.
7, need to adopt insulation protection measures, if the temperature higher than 220 ℃ of measured medium or low fluid temperature is used for crystallization.
Should choose clip model for cooling or heat preservation;
8, pipes, flanges, fasteners, gaskets and flowmeter flange specification to make the appearance of normal equipment operation;
9, do not need to protect, usually in the normal operation of equipment after the goods.
Problem more attacks in the device has just started, because the pipeline purge the unclean, and float by solid particles stuck representation, at the moment indicator pointer is parked in a bearing.
Should first flowmeter at both ends of the valve closed at this moment, and then remove the flange, take out to clean float, installed from scratch again.
Note on the fastening flange nut to balance tight, and take good washer;
10, technology pipeline flange is necessary and meter flange coaxial and parallel to each other, because in order to prevent deformation of pipeline caused by the flow meter.
Pipe supports in order to prevent the pipe oscillation and properly reduce the axial load meter, control valve should be equipment in the flow meter in the measurement system of dirty;
At least 10 cm around 11, equipment, because the appearance is a magnetic coupling so to ensure the appearance of the function of the signal.
12, 13, do not allow the existence of ferromagnetic material under certain pressure calibration if gas export direct emissions to the atmosphere in appearance, measuring the appearance of the gas.
Will happen in the float in the air pressure drop, and lead to data distortion.
If is such conditions, exporting equipment should be in the appearance of a valve;
14, be extra careful.
Because under the effect of uneven pressure equipment when PTFE fabric appearance.
PTFE will deformation, so the flange nut evenly tighten symmetry.
15 and equipment to prevent direct sunlight display as far as possible, with a liquid crystal display appearance.
To prevent falling liquid crystal using stature;
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
However,
mass flow meter isn't the only producer in domestic, and many people feel that Beijing Sincerity Automatic Equipment Co., Ltd's service leaves much to be desired in terms of functionality and design.
Helping our customers manage document workflow and increase efficiency through best-in-class mass flow meter and services. Fostering the growth and development of our employees.
mass flow meter has a very good repute over the global market.
