Abstract: the gas flow meter scale installation instructions information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Gas flowmeter with flange connection flow timing should be consistent with the town gas engineering construction and acceptance standard 'indoor CJJ94 - 2003 2. 2. The provisions of article 6. Gasket inside diameter should not be less than the pipe diameter, gasket diameter should not interfere with the installation of bolts. Flange gaskets are not allowed. More flow meter manufacturers choose model price quote you are welcome to inquire, here is natural gas flow meter scale installation instructions for details. Gas flowmeter with flange connection flow timing should be consistent with the town gas engineering construction and acceptance standard 'indoor CJJ94 - 2003 2. 2. The provisions of article 6. Gasket inside diameter should not be less than the pipe diameter, gasket diameter should not interfere with the installation of bolts. Flange gaskets are not allowed to use oblique gaskets or double gasket. User flowmeter should be installed in the protective box outdoor installation. Gas flow meter should be installed as far as possible close to the riser into position, table before the tube is shorter, reduce the risk of potential leakage, to reduce the installation cost, flow meter can be installed in front of the voltage regulator, but need to be considered for the pressure is stable, for large pressure fluctuation has a certain influence on the working life of the meter. Choose common flow meter range of 0% 70%. Reasonable choose corresponding gas flowmeter types and specifications, especially for measured gas flow rate lower limit to pay special attention to. Commercial use of gas flowmeter installation instructions: rated flow meter less than 50 m3 / h, using high installation, the bottom of the table from indoor ground should not be less than 1. 4 m, away from the wall after the table should not be less than 30 mm, and should add table holds a fixed; Using low installation, should be a right to install in the height of not less than 200 mm brick pier or steel stents, table after wall net margins should be not less than 50 mm. Rated flow is greater than or equal to 50 m3 / h of the flowmeter, should have a right to install the height not less than 200 mm brick pier or steel stents, table after wall net margins should be not less than 150 mm; Turbine table with table and installation location, location and elevation should comply with the provisions of the design documents, and shall point to the installation of product identification. Flowmeter and all kinds of kitchen and equipment level distance shall meet the following requirements: (1) level of with metallic chimney clear distance should not be less than 1. 0 m, and the level of brick chimney clear distance should be not less than 800 mm. Diction and cooking stove, big cookstoves, steam box, such as oven gas stove oven edge level interval should not be less than 800 mm. (3) with the boiling water, and hot water boiler level interval should not be less than 1500 mm. (4) when the flow meter and all kinds of kitchen and equipment of the horizontal distance can't meet the above requirements, should add insulation board. Industrial gas meter installation instructions: industrial enterprises of many sets of parallel installation flowmeter, each flow meter on the import and export pipeline valve should be installed according to the requirement of the design documents; The net distance between flowmeter should be able to satisfy the installation of pipelines, group of flange, repair and change the need of the table, and should not be less than 200 mm. Installation work must first air circulation, can not open flames, near to secure them. Before installation should be closed before the table to cut off the air supply valve, such as homework is inevitable with gas, should wear a mask when necessary, to prevent gas poisoning. And the construction should be at least 2 or more present. Check whether the flow meter is intact before installation, model is in line with the requirements. When installation, such as flowmeter has a mechanical counter header, which prohibit used for hoisting. When installing, avoid external stress is applied to; Nor force make the flowmeter to force in place. Flow meter in place after the welding operation is not allowed. Roots flowmeter when installation, must conform to the level of the installation, otherwise affect need to flow or even breath. Before water pressure on pipeline pressure test, flow meter into line, for pipeline thoroughly clean and dry before you install the meter in place. Must be set before the meter filter, especially turbine and roots flowmeter. Filtration precision is not less than 10 & mu; m。 Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
