1. Does the flowmeter belong to the valve category?
This instrument belongs to the valve category. According to information on Baidu Baike, flow meters belong to the category of flow meter valves. The National Science and Technology Terminology Review Committee defines them as instruments that indicate the measured flow rate and (or the total amount of fluid in the selected time interval). Flow meters are one of the major categories of instruments and devices in process automation. They are widely used in various fields of the national economy, such as metallurgy, electricity, coal, chemical industry, and peoples daily lives. They are important tools for developing industrial and agricultural production, saving energy, improving product quality, enhancing economic efficiency and management level, and occupy an important position in the national economy.

3. Industrial gas flowmeter displays valve closed
Troubleshooting solution for industrial gas flowmeter displaying valve closed
1. Problem diagnosis steps 1 Valve status confirmation check whether the mechanical indicator or actuator of the valve is in the closed position. If it is an electric/pneumatic valve, it is necessary to check whether the control signal (4-20mA or switch quantity) is delivered to the actuator normally. 2. Flow meter signal verification: Use a multimeter to accompany the technician to detect the output signal of the flow meter (such as pulse, analog quantity), compare the actual working condition with the displayed value. If the signal is normal but the display is abnormal, it may be a fault in the internal calculation unit of the flow meter. 3. Check the control system logic to see if the PLC/DCS system logic has set automatic valve closing conditions (such as flow rate exceeding limit, emergency cut-off trigger), and check if the associated sensor (such as pressure, temperature) data is abnormal.
