Abstract: the throttle device applications of two phase flow measuring information produced by excellent
flow meter, flow meter manufacturer to offer you the quotation.
Keywords: throttling device, two phase flow, orifice meter sensor in field measurement of two phase flow fluid has hundreds of years of history, the advantages and characteristics of measurement in the previous article has introduced in detail, for everyone here today, and will give you.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is the application of two phase flow throttling device measurement details.
Keywords: throttling device, two phase flow, orifice meter sensor in field measurement of two phase flow fluid has hundreds of years of history, the advantages and characteristics of measurement in the previous article has introduced in detail, for everyone here today, are mainly introduced to everyone, the technology field of two phase flow main location: 1, the leak.
In the junction of process pipeline, valve and pump seal leak likely, in air in liquid medium.
In the system of the population may also be in the air.
Check system leak, and repair the leakage points have been found.
2, air-pocket and flash phenomenon.
When the system is in or close to process the evaporation of liquid medium under pressure at work, cause bubbles in process in the liquid, can produce air-pocket and flash phenomenon.
If the sensor distance produce pressure drop device (
Such as regulating valve)
Very close, in the device installed upstream of the sensor can reduce the occurrence probability of flash.
Or, to increase the back pressure sensor downstream, can also reduce the occurrence of air pockets and flash phenomenon.
This is the time when the orifice meter used at the scene to pay attention to the throttling parts before and after the pressure to ensure in 0.
The reason why within 75.
3, the system's high.
When measuring liquid, in the high places of the system will collect to carry gas bubbles (
No condensation bubble)
。
If the liquid flow rate is very low, and/or high relative to the system is very high, carry bubbles will stay growth coexist.
If the bubble liquid and through the sensor, measurement error will occur.
One possible solution, that is, according to the requirements of the equipment and procedures.
Point of the system, sensor installed upstream of the emptying valve (
For harmless gas)
Or venting device (
For harmful gas)
。
4, splashed flow & throughout;
。
When the liquid flow rate reduced to only part of the pipe full of sensors, can appear & other
Splash flow & throughout;
Phenomenon.
The reasons for this phenomenon is usually due to the liquid flow down a sensor installed on the vertical lines.
In order to eliminate this kind of situation, liquid should be determined by the vertical upward flow installation of sensors.
This is why the throttle device (
Orifice meter)
At the time of installation, if you encounter any vertical installation, under the condition of the process allows, try to choose the flow of from down to up.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
