Abstract: the advantages and disadvantages of several kinds of air flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Every
flowmeter, in actual use, will have their respective advantages and disadvantages, so we are choosing traffic time, should according to the actual parameters, choose zui suitable flowmeter, in the process of the current industrial automation, used to measure the air flow meter is very.
More flow meter manufacturers choose model price quote you are welcome to inquire, the following are the advantages and disadvantages of several kinds of air flow meter scale article details.
Every flowmeter, in actual use, will have their respective advantages and disadvantages, so we are choosing traffic time, should according to the actual parameters, choose zui suitable flowmeter, in the process of the current industrial automation, there are many kinds of instrument used to measure the air flow, but according to the principle of classification is not much.
In practice, there are usually several reasons could lead to errors flowmeter: 1, the compressor and blower export most involves a certain amount of fluid pulsation.
Fluid pulsation can lead to differential pressure type flowmeter,
vortex flowmeter flowmeter in value on the high side, causing metal rotameter in rotor jumping up and down.
In order to eliminate the influence of the pulse, typically in the export of compressor set a buffer tank filter pulse, and the back of the meter in a buffer tank;
Or install the meter away from the pulse source.
2, the compressed air from the atmosphere, which always contain a certain amount of water vapor in the atmosphere.
Used to measure the compressed air flow of the larger diameter orifice flowmeter, common water before orifice, will affect the accuracy of measurement.
Lead has a tendency to a water pipe, which leads to the differential pressure transmitter to the measurement of differential pressure differential pressure generated by the inconsistent with the throttle device.
These are all air with water a common cause of error.
3, measurement of compressed air flow meter, typically installed in the compressor room and blower room, and the vibration produced by compressor and blower will be through the air pipe or duct to far away places.
Vibration caused the vortex flow sensor with vibration frequency corresponding to the interference signal, causing traffic greatly value is on the high side.
4, pig flowmeter for large caliber air flow measurement has its unique advantages, the price is cheap, simple and reliable, easy installation and maintenance is its significant advantages, is vortex street flowmeter and the throttle differential pressure flowmeter.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
The increasing consumption demand in key segments such as v shape
coriolis mass flow meter, rosemount coriolis mass flow meter and coriolis density meter have been driving the sales of and its derivatives worldwide.
