How many methods are used to measure gas flow? How is it measured?
The large bore air flow measurement has its unique advantages, such as low price, simple and reliable, easy installation and maintenance. It is a supplement of vortex flowmeter and throttling differential flowmeter. Tags: flowmeter, vortex flowmeter, rotor flowmeter, differential pressure flowmeter, pitot tube flowmeter
Most of the fluid at the compressor and blower outlet contains a certain pulsation. Fluid pulsation causes differential pressure flowmeter, vortex flowmeter and other flow meters showing higher value, causing the rotor of the flowmeter to jump up and down. In order to eliminate the influence of pulsation, a buffer tank is usually installed at the outlet of the compressor to filter out the pulsation, and the flowmeter is installed behind the buffer tank, or the flowmeter is installed away from the pulse source.
Compressed air is taken from the atmosphere, and the atmosphere contains a certain amount of water vapor. A large bore orifice flowmeter used to measure the flow of compressed air. There are always accumulated water in front of the orifice, which affects the measurement accuracy. There is usually a section of water in the draft pipe, which makes the differential pressure measured by the differential pressure transmitter not consistent with the differential pressure produced by the throttling device. These are common causes of air borne water errors.
To measure compressed air, the flowmeter is usually installed in the compressor room and the blower room, while the vibration generated by the compressor and blower is transmitted far through the air duct or air duct. The vibration causes the vortex flow sensor to produce an interference signal corresponding to the vibration frequency, resulting in a large flow indication.
