The vortex flowmeter is a volume flowmeter, that is, the fluid Reynolds number is within a certain range, and its output is only proportional to the volume flow. The output of the vortex flowmeter has a frequency signal and an analog signal, and the analog output is obtained by f/I conversion on the basis of the frequency output. There is about a 0.1% loss of accuracy in this conversion. Therefore, when used to measure steam flow, users prefer to use frequency output.

Several other reasons why the frequency output vortex flowmeter is more popular with users such as heating companies are as follows.
There are many types of electrodes for electromagnetic flowmeters. The conventional ones are 316L, Hastelloy, titanium, tantalum,
platinum-iridium alloy and so on. So here, Shanghai JSN Instrument Co., Ltd. will share with you the tips for selecting electrodes:
As long as it is used to measure water, choose 316L electrode, which is economical and affordable;
As long as the medium contains a certain amount of acid and alkali, instead of hydrofluoric acid, oleum and alkali, then choose a tantalum
electrode, which can withstand the corrosion of most chemical media.
The gas mass flow meter is not affected by temperature and pressure changes, and its display reading directly indicates the mass flow rate of
the gas. It is applicable to a wide range of measurement ranges, and can be used in small flow places in the laboratory and large-scale devices
in factory production.
Working principle of gas mass flow meter
Gas mass flow controller is a kind of thermal conductivity instrument. At present, many countries have industrial products of this kind of meteor meter. Although the specific structure is different
