What are the precautions for using natural gas flowmeters? Posted by : admin / Posted on : Jun 23, 2020

We know that the flowmeters for measuring natural gas mainly include flowmeters such as gas waist wheel (Roots) flowmeters, gas turbine flowmeters, precession vortex flowmeters and orifice flowmeters, and know that Roots flowmeters should measure natural gas. Attention, then what should be paid attention to when using gas turbine flowmeter and precession vortex flowmeter, which are also commonly used to measure natural gas?
The gas turbine flowmeter has a simple structure and is easy to install. It is often used to measure the flow of natural gas. However, when the turbine of the turbine flowmeter rotates at high speed, mechanical friction will occur between the bearing and the shaft, so pay attention to lubricating it, which can be provided according to the manufacturer. Method for regular replenishment of lubricating oil. At the same time, if the high-speed flowing gas contains large solid particles, it will easily damage the turbine blades, so a filter should be installed in the pipeline in front of the turbine flowmeter.
The precession vortex flowmeter is also widely used in the measurement of natural gas. It has a wide operating temperature range, strong applicability, and low requirements on the upstream and downstream straight pipe sections. Its main disadvantage is that the pressure loss is large, and The precession vortex flowmeter is a fluid vibration type flowmeter, which is relatively sensitive to pipeline vibration and electromagnetic interference. Therefore, it should be fully considered in the field environment with less vibration and no electromagnetic interference during installation.
