Precautions for use:
Steam vortex flowmeter is mainly used for industrial pipelines in the steam medium fluid flow measurement, steam vortex flowmeter is characterized by small pressure loss, large range, and high accuracy, in the measurement of the volume flow of the working condition is almost independent of the fluid density, pressure, temperature, viscosity, and other parameters. Used to measure the medium: gas, liquid, vapor, is a more advanced, ideal flow meter. Steam vortex flowmeter use what needs to pay attention to the problem? 1. Don’t let the vortex flowmeter be strongly collided during transportation, and don’t let it be wetted by rain. 2. 2. Use our packaging as much as possible to transport the steam flowmeter directly to the installation site. 3. when you get the steam flowmeter, please make sure that there are no bumps and scratches, etc. during transportation. 4. Make sure that the model number matches the one you are buying according to the label on the product nameplate. 5. When storing the vortex flowmeter, try to use the original packaging for storage, and the storage place should meet the following requirements: ① the place where there will be no rain ② the place where there will be as little vibration or collision as possible ③ Temperature: -40 ℃ – +55 ℃ ④ Humidity: 5% -90% 6. When storing the vortex flowmeter, please clean all residual liquid and adhesive materials inside the vortex flowmeter. When used vortex flowmeter is used, the internal residual liquid and adhesion should be completely cleaned, and the power connector should be sealed to prevent moisture. 7. 7. Use the flowmeter in the specified conditions, beyond the provisions of the use is not feasible, if the flowmeter is damaged, the cost of repair will be borne by yourself. 8. After the steam vortex flowmeter has a problem, contact us or the repairer as soon as possible, do not blindly repair by yourself.
Straight pipe section installation requirements:
1. the flow meter must be installed horizontally in the pipeline (pipeline tilt within 50), the installation of the flow meter axis should be concentric with the axis of the pipeline, and the flow direction should be the same. 2. The length of the pipeline upstream of the flowmeter should be not less than 10D equal diameter straight pipe section, if the installation place is allowed, it is recommended that the upstream straight pipe section of 20D, downstream of 5D. Precautions for the installation of vortex flowmeter for steam, the requirements of piping: flowmeter installation point of the upstream and downstream piping of the same diameter as the inner diameter of the flowmeter. Precautions for the installation of steam flowmeter, bypass pipe requirements: To ensure that the steam vortex flowmeter maintenance does not affect the normal use of the medium, before and after the flowmeter should be installed on the pipeline cut-off valve (shut-off valve), and should be set up at the same time the bypass pipe. Flow control valve should be installed in the flowmeter downstream, steam vortex flowmeter flowmeter installed upstream of the shut-off valve must be fully open, to avoid the upstream part of the fluid to produce an unsteady flow phenomenon.
Requirements of the external environment:
Steam vortex flowmeter is best installed indoors, must be installed outdoors, and be sure to use the sun, rain, and Lightning protection measures, so as not to affect the service life. Installation: The flowmeter should be installed in a place where it is easy to maintain and where there is no strong electromagnetic interference and heat radiation. Installation of welding requirements: 1. Before installing the flow meter should be cleaned of debris in the pipeline: debris, welding slag, stones, dust, etc. It is recommended in the upstream installation of a 5-micron sieve filter for blocking liquid droplets and sand particles. It is best to blow the pipe with an equal-diameter pipe (or bypass pipe) instead of the flowmeter. To ensure that the flowmeter is not damaged in the process of use. 2. Users with another pair of standard flanges welded to the front and rear piping. Welding with a flowmeter is not allowed! 3. When installing the flowmeter, the sealing gasket between the flanges must not be recessed into the pipe to prevent interference with normal flow measurement. Flowmeter grounding requirements: The steam vortex flowmeter flowmeter should be reliably grounded, and can not be shared with the strong power system ground.
