Abstract: the gas vortex flow meter
scale correct installation information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Gas vortex flowmeter can be widely used in large, medium and small various pipeline for compressed air, saturated and superheated steam, gas and all kinds of medium flow measurement and can be used as flow transducer is applied to automatic control system, has the security, stability, use.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is a gas scale vortex flowmeter installation article details correctly.
Gas vortex flowmeter can be widely used in large, medium and small various pipeline for compressed air, saturated and superheated steam, gas and all kinds of medium flow measurement and can be used as flow transducer is applied to automatic control system, has many characteristics, such as security, stability, long service life.
Measurement of steam vortex flowmeter installation should pay attention to the key points: 1.
Upstream and downstream straight pipe must have enough.
If the sensor installed upstream of point on the same plane has two 90.
Elbow, are: straight pipe upstream & ge;
25 d, the downstream straight pipe & ge;
Regulating valve should be installed on the downstream side of the sensor outside 5 d, if must be installed in the upstream of the sensor, the sensor straight pipe upstream should be not less than 50 d, downstream should be not less than 5 d.
Choose the installation location and environment.
To avoid the strong power equipment, high-frequency equipment, strong power switch device;
To avoid the influence of high temperature heat source and the radiation source, to avoid strong vibration and strong corrosive environment and so on, at the same time to consider easy installation and maintenance.
Pipeline vibration reduction measures.
Sensor to avoid installed in the strong vibration, transverse vibration in particular.
If need to install the anti-vibration measures must be taken, respectively at the upstream and downstream of sensor 2 d piping fastening device, and vibration-proof pad.
Upstream and downstream piping should be installation points and the sensor concentric, coaxial deviation should be no less than 0.
The installation of sensors in a vertical pipe.
Measuring gas flow rate, the sensor can be installed in vertical pipe runs, flow to the unlimited.
If the measured gas containing a small amount of liquid, gas flow should be from the bottom up.
Measuring the liquid flow rate, liquid flow shall be from the bottom up: it won't attach additional liquid weight on the probe.
Installed in horizontal pipe runs is flow sensor zui installation method in common use.
Measuring gas flow rate, if contain a small amount of fluid in the gas being measured, the sensor should be installed in the pipeline is relatively high.
Measurement of liquid flow, if the liquid contains a small amount of gas being measured, the lower part of the sensor should be installed in the pipeline.
Sensors in a horizontal pipe of inversion.
Generally do not recommend using this installation method.
This installation method is not applicable to measure the general gas, superheated steam.
Can be used for measurement of saturated steam, high temperature suitable for measuring the liquid or frequent cleaning pipelines.
Sensors in a horizontal pipe to the side.
Regardless of what kind of flow measurement, the sensor can be in the upper horizontal pipeline, especially the measurement of superheat steam and saturated steam and low temperature liquid, if the condition allows zui to good use side, so the temperature of the fluid have less effect on the amplifier.
The choice of pressure and temperature measuring points.
According to the demand of measurement should be near the sensor to measure the pressure and temperature, the pressure measuring point should be 3 - of the downstream of the sensor
5 d, temperature measuring points should be 6 - of the downstream of the sensor
The installation of sensors on have insulation pipe.
When measuring high temperature steam, thermal insulation layer zui much can't more than a third of the bracket height.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
