Installation of turbine meter scale which aspects need to be paid attention to

Abstract: the installation of turbine meter scale which aspects need to pay attention to the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. To the requirement of explosion-proof products: for the instrument safety normal use, should check whether the use environment of explosion-proof type flowmeter with stipulations in user explosion-proof requirements, and installation, in use process should strictly abide by the national explosion-proof products use requirement, the user may not be. More flow meter manufacturers choose model price quote you are welcome to inquire, here is installed turbine meter scale which aspects need to pay attention to the article details. To the requirement of explosion-proof products: for the instrument safety normal use, should check whether the use environment of explosion-proof type flowmeter with stipulations in explosion-proof user demands, and installation, in use process should strictly abide by the national explosion-proof products use requirement, the user must change the connecting way of explosion protection system, not to open the instrument. Selection within the prescribed scope of traffic to prevent the overspeed operation, to ensure the desired accuracy and ensure the normal service life. Should clean up the pipe before installation flowmeter clutter: fragments, welding slag, stones, dust and other recommend installed upstream in 5 micron mesh filter is used to block the droplets and the grains of sand. Flowmeter of commissioning should slowly open valve before first, when after open the valve and prevent the instantaneous flow and damage to the turbine. Add lubricant should be according to the sign, the number of refueling depends on temperament clean degree, usually 2 - every year 3 times. Due to pressure test, purging pipes or exhaust turbine overdrive, and turbine operation will damage may make flowmeter in the reverse flow. Not allowed to open the former meter run time. Back cover, change the internal related parameters, otherwise will affect the normal operation of the meter. Mounting pad carefully and make sure there are no outstanding content into the pipeline, in order to prevent interference with the normal flow measurement. When flowmeter calibration to collect pressure on the flow meter to take pressure. : to the requirement of straight pipe flowmeter level must be installed on the pipeline, Tilted pipe within 5) Axis, installation flowmeter should be concentric to the pipe axis, flow direction should be consistent. Flowmeter upstream pipe length should be not less than 2 d straight pipe section, if the installation site allows advice straight pipe upstream to downstream of 20 d, 5 d. : to the requirement of pipe flow meter of the inner diameter of the upstream and downstream piping installation points and the flow meter diameter is the same. : to the requirement of by-pass pipe in order to ensure not affect the normal use of medium maintenance flow, the flow meter should be installed to cut off the valve in the pipeline before and after ( Globe valve) The by-pass pipe shall be set up, and at the same time. Flow control valve to be installed downstream of the flow meter, flowmeter upstream of the valve must be fully open when using, avoid the upper part of the produced fluid unsteady flow phenomena. The requirement of external environment: good flowmeter zui installed indoors, must be installed in the outdoor, be sure to use prevent bask in, prevent the rain. Lightning protection measures, so as not to affect the service life. In the medium containing impurities requirements: in order to ensure the service life of the flow, should be installed in front of the straight pipe flowmeter of filter. Installation site: the meter should be installed in the convenience of maintenance, without strong electromagnetic interference and thermal radiation of the site for the installation of welding requirements: the user to match a pair of standard flange welding on the pipe before and after. Not allowed to take meter welding! Before install flowmeter should strictly eliminate dirt such as welding slag in the pipeline, zui works such as the diameter of the pipe ( Or the by-pass pipe) Instead of flowmeter for venting pipe. In order to ensure that in use process flow meter from being damaged. Install the flow time, the sealing gasket between the flange cannot be sunken into the pipe. Meter grounding requirements: flowmeter should be reliable grounding, not common ground with high voltage systems. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
