Metal tube flow meter scale installation techniques

Abstract: metal tube flow meter scale installation technique information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Metal pipe flow meter is commonly used in industrial automation process control flow of a measuring instrument, it can be used to measure liquid, gas flow rate, particularly suitable for low velocity of small flow of medium flow measurement. Try to avoid direct sunlight, high temperature when installation. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a metal tube flow meter scale installation tips for details. Metal pipe flow meter is commonly used in industrial automation process control flow of a measuring instrument, it can be used to measure liquid, gas flow rate, particularly suitable for low velocity of small flow of medium flow measurement. When installation should avoid direct sunlight, high temperature environment so as not to reduce the capacity of lithium-ion batteries and longevity. In order to guarantee the normal work of the metal tube float flowmeter and meet the requirements of measurement precision, the general should pay attention to the following: 1, fluid flows from bottom to top, flowmeter, metal tube flow meter must be installed vertically. And vertical degree is less than 2 & deg; When mounted horizontally level Angle, less than 2 & deg; To handle the fault or blow does not affect production; Piped in process of metal tube float flowmeter should add bypass. 2, export should be 250 mm straight pipe, metal pipe flow meter at the entrance of straight pipe length should be more than 5 times the pipe diameter. To ensure the instrument measuring precision. 3, if the medium containing ferromagnetic materials, consideration should be given between the valve and straight pipe equipped with magnetic filter. 4, when used for gas measurement, should guarantee the pipeline pressure is not less than five times the pressure losses of flow meter to float a stable job. For thermal protection measures, if the medium to be measured temperature higher than 220 ℃ or prone to crystallization when the fluid temperature is too low, should choose clamp cover model, for cooling or heat preservation. 5, pipes, flanges, fasteners, gaskets and flow meter installed and run the flange standard to make the same instrument. 6, the product after normal operation, the device does not need maintenance. Tend to occur in the fault device has just run time, because the pipeline blow wash not clean, and float by solid particles sticking phenomenon, at this time of indicator were stopped at a particular location. The first should be closed the valve on both sides of the flowmeter, remove the flowmeter, float for washing, Note: the level of installation of the flowmeter directly remove the flange, remove float for cleaning; When installation, good washer, screw to balance tight) Packed again. 7, process piping flange must be flange with meter coaxial and parallel to each other, in order to avoid deformation caused by pipe flowmeter. Appropriate increase pipe supports in order to avoid pipeline vibration and reduce the axial load meter, 8, in order to guarantee the performance of the instrument, instrument installation where at least 100 mm, do not allow the existence of ferromagnetic material, because the instrument is through the magnetic coupling signal. 9, the measuring gas meter, in particular under pressure calibration, such as export direct emissions to the atmosphere, will produce pressure drop on the float, and cause data distortion; If this is the working condition, a regulating valve should be installed in the instrument's export. 10, due to the uneven pressure, under the action of the installation of PTFE lining instrument, PTFE will be out of shape, so the flange nut evenly symmetric tighten the above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.

The , essentially perfected by vortex flow meter manufacturer, is one of the first home appliance to be widely distributed.
