1. The installation requirements for flow meters are summarized as follows:
Flow meter installation requirements are summarized as follows:
1. Basic installation requirements: Flow direction should be consistent: in horizontal pipelines, vortex generators should be installed vertically. In vertical pipelines, flow meters require a bottom in and top out direction. Pipeline diameter matching: The pipeline diameter should be consistent with the instrument diameter, and if not, it needs to be reduced or expanded. Pay attention to the difference in inner diameter between different standards (such as DIN, ANSI) and national standard G. Smooth inner wall of pipeline: Ensure that the inner walls of the pipeline on both sides of the flowmeter are smooth and free of obstacles such as welding. Good alignment: The flowmeter needs to be maintained in good alignment during installation. Gasket requirement: The gasket should not be inserted into the pipeline to avoid affecting flow measurement. Straight pipe length rolling rubber: The length of the straight pipe section in front of the instrument should be at least 20D (D is the diameter of the pipeline), and the outlet should be at least 10D. If there are multiple elbows, valves, etc. at the inlet, the straight pipe section should be longer. Pipeline vibration: The pipeline should not have strong vibration, and vibration objects such as electric motors and water pumps should be avoided during installation. If necessary, support the flowmeter or connect it with a hose.
2. Installation precautions for different flow meters Electromagnetic flow meters: Static grounding is required to ensure safety.
. Quality flowmeter: It needs to be supported to avoid interfer
3. The installation of different flow meters requires a rotor flow meter with a diameter of not less than 0-5 times the pipe diameter upstream, and no requirements downstream.
. Target flowmeter: upstream not less than 5 times the pipe diameter, downstream not less than 3 times the pipe diameter. Turbine flowmeter: upstream not less than 5-20 times the pipe diameter, downstream not less than 3-10 times the pipe diameter. Vortex flowmeter: upstream not less than 10-40 times the pipe diameter, downstream not less than 5 times the pipe diameter. Electromagnetic flowmeter: upstream not less than 5-10 times the diameter of the Zenbei Mountain pipe, downstream not less than 0-5 times the diameter of the pipe. Ultrasonic flowmeter: upstream not less than 10-50 times the pipe diameter, downstream not less than 5 times the pipe diameter. Positive displacement flowmeter: There is no requirement for the length of the straight pipe section. Orifice plate: upstream not less than 5-80 times the pipe diameter, downstream not less than 2-8 times the pipe diameter. Nozzle: Upstream not less than 5-80 times the pipe diameter, downstream not less than 4 times the pipe diameter. Venturi tube, bent tube, wedge-shaped tube: upstream not less than 5-30 times the pipe diameter, downstream not less than 4 times the pipe diameter. Uniformity tube: upstream not less than 3-25 times the pipe diameter, downstream not less than 2-4 times the pipe diameter. Thermal g
