Abstract: how to make the compressed air flow meter scale quantity information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Compressed air, namely by the external force of compressed air.
Air compressibility, the air compressor to do mechanical work make itself shrinkage and improve after the air is compressed air pressure.
Compressed air is an important source of power.
Is compared with other energy, it has.
More flow meter manufacturers choose model price quote you are welcome to inquire, here's how to compress the air flow meter scale article details.
Compressed air, namely by the external force of compressed air.
Air compressibility, the air compressor to do mechanical work make itself shrinkage and improve after the air is compressed air pressure.
Compressed air is an important source of power.
With other than energy, it has the following obvious characteristics: clear transparent, transportation is convenient, no special performance of harmful, no fire danger, not afraid of overload, can work in many adverse environment, the air on the ground, everywhere, all the inexhaustible.
Huaian ruentex group a instrument, working principle and characteristics of the vortex
flowmeter, vortex flowmeter is based on the principle to measure the karman vortex street an internationally advanced level meter, because it has the advantages of other flowmeter it too got rapid development since the 1970 s, according to relevant data shows, Japan, Europe and the United States and other developed countries now use the sharp rise in the proportion of vortex flowmeter, has been widely used in various fields, will be dominant in the future flow meter, zui orifice flowmeter is the ideal alternative products.
Vortex flowmeter in the measuring pipe set a vertical pillars, on both sides of the fluid through the pillars alternately with the rules of the vortex, the vortex also referred to as the karman vortex street.
The release of the karman vortex street frequency and the fluid flow velocity and the width of the pillars, available under type: type of f - the release of the karman vortex street frequency;
The Sr - sensor coefficient (
Referred to as' lo ha)
；
V - velocity;
D - the width of the columns from this formula can be seen, the instrument coefficient of Sr and pillars width d unchanged, the frequency of the karman vortex street is proportional to the velocity of the fluid, therefore, by measuring the release of the karman vortex street frequency can calculate the instantaneous flow rate of the pipe inner fluid.
KTLU series vortex flow sensor spiral release frequency is according to the vortex alternately stress acting on the detection sensor, through its internal piezoelectric element to detect.
Second, the measurement system composed of high pressure air flow measurement system by huaian ruentex group RTLUGB vortex flow sensor and the composition of intelligent flow totalizer. especially.
Vortex sensor mainly by sensors,
There were amplified board)
, connecting rod, vortex generator components (
There a triangular prism, probes)
Form and can be used for superheated steam and saturated steam, compressed air and gas measurement.
In this measurement system, vortex flow sensor installed in vertical pipe runs, it will work with high pressure air flow the pulse signal sent to the corresponding intelligent flow integrating instrument.
To adopt advanced technology of single chip microcomputer intelligent flow totalizer. especially, can cooperate with vortex flow sensor or orifice plate flow measurement flow sensor, it has a full Chinese LCD display, can display the instantaneous flow, transient heat and cumulative flow, accumulative total quantity of heat, vortex street frequency, the density of medium temperature, pressure, time and date, and other information, but also has small flow automatic compensation, power flow compensation, rich functions such as automatic meter reading.
Access to the temperature and pressure signal can automatically compensate the temperature and pressure.
It converts pulse signal from the flow sensor for the instantaneous flow and cumulative for local display, and output a is proportional to the instantaneous flow rate of 4 ~ 20 ma signal, for easy connection with DCS.
Third, the matters of attention in the use 1.
Properly installed properly installed sensors is to ensure that the first premise of measurement accurate and reliable, if on the installation location and the way to select error light person affect measuring accuracy, the person that weigh can affect the service life of the sensor, and even damage the sensor.
Straight pipe (1) to ensure proper installation of sensor, the length of straight pipe upstream of 15 - general requirements
40 dn, downstream length 5 dn, according to the situation of upstream and downstream piping appropriate adjustments, to ensure the accuracy of measurement.
Sensor should also avoid the overhead of very long pipe installed on the sensor, after such a long time, because of the sensor sag easily between the sensor and the flange seal leakage, if necessary to install, must be set separately in the upstream and downstream of sensor 2 d pipe bracket fastening device, etc.
