1. Vortex flowmeter only one-way measurement, installation, pay attention to ensure that the media flow direction and flow meter arrow direction consistent. 2. Vortex flowmeter installation is the best way to install vertical, bottom-up flow through the flow meter. Will be installed on the vertical pipe flow meter, flow direction from bottom to top. 3. Horizontal installation, the flow meter must be installed in the high pressure area of ​​the system, and ensure that the corresponding outlet pressure; Do not install the highest point in the pipeline, because the highest point of gas accumulation, the pipeline is not full, the outlet can not be directly vent. 4. When measuring the temperature of the fluid, try to use vertical installation; if have to be installed horizontally, please send the transmitter part of the flow meter vertically down, or horizontal side to avoid overheating; pay attention to the air flow at the installation location Or well-ventilated. 5. Straight pipe requirements: at least to ensure that the flowmeter before 15 times the diameter of the flowmeter after 5 times the diameter. Such as the flow meter before the elbow, indentation, expansion and other sources of interference, you need to ensure that the flowmeter 30-40 times the diameter, flowmeter 6 times the diameter. Flow meter should be installed in the control valve, pressure or temperature sensor upstream. 6. Installation note pipe diameter should be slightly larger than or equal to the instrument's diameter. 7. When using the seal ring, pay attention to the inner diameter of the seal ring should be slightly greater than or equal to the inner diameter of the instrument, the center of the seal ring is located in the center of the pipe. Cable entry seal The electrical connection of the instrument must be observed with the sealing of the entry opening. The corresponding sealing connection (m20χ1.5; 1/2 "npt; g1 / 2") must be selected according to the instrument cable entry type and installed correctly and tightly. There is no sealed connector, or install careless, fail to seal effect, is one of the most common instrument damage.
