EspañaAt present, the flowmeters commonly used for measuring natural gas in China mainly include gas waist flowmeters, gas turbine flowmeters, precession vortex flowmeters and orifice flowmeters. Now let's take a look at the advantages of the gas waist wheel flowmeter when measuring natural gas, and what problems should be paid attention to at the same time.
Gas waist wheel flowmeters (also known as roots flowmeters) can be used not only to measure the flow of dry gas, but also to measure the flow of moisture (associated gas), while orifice flowmeters and gas turbine flowmeters are not It is suitable for measuring associated gas containing droplets. Therefore, the gas waist flowmeter has certain advantages in this respect. So, what should be paid attention to when using Roots flowmeter to measure natural gas? Let's take a closer look:
1. Because natural gas may contain some impurities, it is generally necessary to install a filter upstream of the flowmeter to prevent the flowmeter from being blocked or stuck, and to periodically drain, check and clean the filter;
2. In order to prevent liquid accumulation during the measurement of the flowmeter, the flowmeter should be installed vertically or above the process pipeline as much as possible, and the liquid accumulation should be discharged regularly;
3. Before the flowmeter is put into use, it should be checked whether there are impurities such as welding slag, if any, it should be cleaned, and a bypass should be opened to prevent damage to the flowmeter at high speed;
4. There should be regular observation by on-site personnel to pay attention to the pressure before and after the flowmeter to judge and find the fault in time.
