gas flow meter

The precession vortex flowmeter has certain advantages in the measurement of natural gas, which are specific?

1. After power-on, there is fluid flow in the pipeline, but the vortex flowmeter has no signal output

Compressed air is generated by air compressor or high pressure fan. When these devices are in operation, they all have varying degrees of vibration, and sometimes the vibration is relatively strong, and this vibration is transmitted through the connecting pipe.

The vapor flowmeter has no moving parts, strong reliability, high precision, long life, and can measure the instantaneous flow and cumulative flow of liquid in a wide flow range.

The installation of the vortex flowmeter has different provisions, used to measure different measured media, different positions, then the installation method is not the same, the attention point is different, generally speaking, the vortex flowmeter has the following specified points:

What are the advantages and precautions of the thermal gas mass flow meter?

In order to ensure the long-term normal operation of the gas turbine flowmeter, it is necessary to check the running status of the flowmeter frequently, do maintenance work, and eliminate problems in time.

The precession vortex flowmeter is a kind of velocity flow meter, which can be used for the flow measurement of oil, steam, natural gas and other media, and realize the online automatic compensation of dynamic parameters such as pressure, temperature and compression coefficient, which can not only display various parameters on the spot, but also can transmit various signals far out.

The following aspects must be paid attention to when measuring natural gas with the precession vortex flowmeter:

There are many things to pay attention to in the installation of the temperature and pressure compensation gas turbine flowmeter, such as: the need for good grounding, the need to install filters during installation and the requirements of the installation environment, etc., only we really understand its installation precautions, can effectively ensure the measurement accuracy and service life of the gas turbine flowmeter.

In order to solve the problem of leakage caused by poor measurement accuracy or inability to measure below the lower limit of the instrument, a new type of thermal gas mass flowmeter is developed based on the theory of forced convection heat transfer and the principle of hot wire anemometer. The sensitivity of the instrument is greatly improved and the dead zone of the instrument is reduced by using microfilament structure in the sensitive element and the velocity measuring heating element.

Intelligent vortex flowmeters can measure air. Vortex flowmeter is a new flowmeter for flow measurement based on Karman vortex principle. It has good medium adaptability and can directly measure the volume flow of various media (including air). When measuring air, the vortex flowmeter generates regular vortices through the triangular column vortex generator set in the fluid, and the frequency of these vortices is proportional to the average velocity of the measured medium, so that the air flow can be calculated.

Thermal gas mass flowmeter has certain operating procedures and precautions in use, and must pay attention to these points when in use:

The reason why the thermal gas mass flowmeter is so popular is mainly due to its many advantages and wide application scenarios. Here’s a breakdown of why it’s popular:
