Thermal Gas Mass Flow Meter Wiring Instruction

Note: (This is demonstrated by the accumulator, PLC system with (4~20)mA receiving function or other devices can be wired in this way.)

Installation Requires

Installation of the flowmeter should be away from elbows, obstacles, reducers and valves to ensure a stable flow field, one side of the upper limit requires a longer straight pipe, the front straight pipe length is greater than 10D, after the straight section is greater than 5D. the following chart for the field often encountered in several cases of the required length of the straight pipe section:

Installation Precautions

1. If the thermal gas mass flow meter is installed outdoors, it should be covered with a meter sunshade to avoid sunshine and rain.
2. Prohibit installation in strong vibration occasions.
3. Prohibit exposure to environments containing large amounts of corrosive gases.
4. Do not share the power supply with inverters, welding machines and other equipment that pollute the power supply. If necessary, install purified power supply for the converter.

Application

Tips: Advantages of Thermal Gas Mass Flow Meter

• It is convenient and accurate to measure gas flow without temperature and pressure compensation.
• Compared with the general measuring equipment, the gas flowmeter has good seismic performance and long service life. The sensor has no moving parts and pressure sensing parts, and is not affected by vibration on the measurement accuracy.
• Easy installation and maintenance. If site conditions permit, it can be installed and maintained without stopping production.
• Digital design. Overall digital circuit measurement, accurate measurement, easy to maintain.
