Precautions for installation of thermal gas mass flowmeter

Author:    Source:    Date: 2021-05-13 15:29:43
Thermal gas mass flowmeter is an instrument that measures flow based on the principle of heat conduction. The instrument uses the constant temperature difference method to measure the mass flow of gas. The advantages of thermal gas mass flow meters are many. After all, they are small in size, easy to install, and accurate in measurement.

Of course, there are many precautions for installing thermal gas mass flow meters. The sensor of the hot gas mass flowmeter consists of two reference platinum resistance temperature sensors, one of which measures the temperature of the flow, while the other maintains a constant temperature difference above the temperature.

When installing the hot gas mass flowmeter, it should be noted that the welding operation should not be carried out in an explosive environment. It is not advisable to carry out the installation according to the base, which is generally divided into standard type and simple type. When installing, the base should be located at the top of the pipe section direction.

When installing the thermal gas mass flowmeter, before the special stainless steel valve is fastened to the base on the welded pipe, this is to install the ball valve, and the hole needs to be punched after installation. Before drilling, it is necessary to determine the site environment to ensure the safety of operation and installation. After drilling, the valve needs to be closed in time to avoid air leakage.

Everyone needs to pay attention to the installation of the instrument. Pay attention to the direction of the display, it can be changed.

In short, you need to pay attention to these installation problems, do not blindly install the thermal gas mass flowmeter, which has a great impact on the safety of the installation.
