Smart Water Meter Installation Guide

Abstract: Smart water meter installation guide information is provided to you by excellent flowmeter and flowmeter production and quotation manufacturers. Smart Water Meter Installation Guide A water meter is a flow meter, a measuring instrument for correct measurement and rational distribution of water resources. Wang Dongwei, director of the flow room and associate researcher of the China Institute of Metrology, pointed out in an interview with reporters a few days ago that in order to ensure the water meter. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the smart water meter installation guide article. Smart Water Meter Installation Guide A water meter is a flow meter, a measuring instrument for correct measurement and rational distribution of water resources. Wang Dongwei, director of the flow department and associate researcher of the China Institute of Metrology, pointed out in an interview with reporters recently that in order to ensure the accuracy of water meters, while implementing strong inspection and strengthening supervision and management of water meter products on the market, the installation and use of water meters should also be Pay attention to other aspects. Water meter installation specifications Three factors to be considered in water meter installation Correct installation of water meters is a necessary guarantee to ensure the accuracy of water meter measurement. Water meter national standard GB/T778.2—1996 is the standard on water meter installation requirements. The installation of water meters must consider safety, convenience and correct reliability. The installation of the flowmeter for measuring water can refer to its corresponding requirements. 1 Safety (1) Before installing the water meter on the newly laid pipeline, the sundries in the pipeline must be cleaned before installation, so as not to damage the water meter or affect the normal operation of the water meter after the water is passed through. (2) When the water meter is installed, it must be considered that the water pressure and water temperature used on site are within the maximum operating pressure and maximum operating temperature of the water meter. When installing a small-caliber civil water meter, you should also pay attention to whether the connecting pipe and pipe nut of the water meter feel particularly thin, so as to avoid installing fake and inferior water meters. (3) Water meters installed outdoors should generally be installed with a protection box, and should not be installed in exposed and frozen places to prevent external damage. In severe winter, water meters installed outdoors should have antifreeze measures. Note: Water supply companies in the north (north of the Yangtze River) stipulate that the location of water meters installed outdoors is generally below the permafrost layer. Indoor heating can ensure that the indoor water meters are not frozen and cracked, but the situation is better than that in the south. (4) Anti-theft should be considered, especially copper shell water meters. (5) The location where the water meter is installed should also avoid the erosion of corrosive gases. (6) If the industrial water meter is installed near the boiler, a check valve should be installed behind the meter to prevent the hot water from flowing back and damaging the water meter parts. 2 Convenience The installation location of the water meter should be as convenient as possible to read and read the meter, and the convenience of maintenance and meter replacement should also be considered. (1) For water meters installed outdoors, it is necessary to choose a location that is dry, sand-proof, groundwater-proof, and insect-proof. (2) When the water meter is installed underground, in order to facilitate the replacement of the water meter, two stop valves must be installed at both ends of the water meter. The water passage area of ​​the expansion device (telescopic tube, water filter tank, water filter net) installed at the front of the water inlet of the water meter should be 1 to 2 times the diameter of the water meter, so as to facilitate frequent inspection, replacement or cleaning. 3 Correctness The installation of the water meter must meet the requirements of its working mode, and it should meet the requirements of the water meter in terms of installation orientation, dial orientation and upstream and downstream straight pipe sections. (1) Most water meters have installation method requirements. H on the dial or nameplate stands for horizontal installation, V stands for vertical installation, without these two symbols, it can be installed in any direction. The dial of the water meter should be upward and not tilted. The flow direction of the water meter should be consistent with the flow direction of the water in the pipeline. Some water meters (such as volumetric water meters, etc.) can be installed in any direction. (2) The water meter should be installed so that the direction of the arrow on the case is consistent with the flow direction of the water in the pipe, and it should be installed coaxially with the pipe. (3) The dial of the water meter installed horizontally is generally upward and shall not be inclined. It is not possible to adjust the orientation of the indicator dial of the reading water meter just considering the convenience of reading. Description: Some dry water meter fishing reading indicators can be 360‘Rotate for easy reading. When the water meter is installed vertically or obliquely, the impeller shaft and the centerline of the pipe must be kept parallel. (4) The straight pipe sections upstream and downstream of the water meter must meet the requirements of the instruction manual, especially for speed-type water meters. Horizontal screw-foil water meters and single-beam water meters are particularly required for straight pipe sections. Downstream of the water meter, there should be a part higher than the water meter (such as a faucet) or maintain a certain pressure, so that the water meter can always operate under the condition of a pipeline full of water. (5) The position of any pipeline downstream of the water meter should be higher than the position of the water meter to ensure that the water meter works under the condition of full pipe flow. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. Smart Water Meter Installation Guide
