Installation points and application range of remote water meter

The remote water meter is composed of an ordinary mechanical water meter and an electronic collection and transmission module. The electronic module completes signal acquisition, data processing, storage and uploads the data to the repeater or the hand-held meter reading device through the communication line. The body adopts an integrated design, which can record and save the user's water consumption in real time, or directly read the current accumulated number. Each water meter has a code. When the smart water meter receives the meter reading instruction, it can upload the water meter data to the management immediately. system
Remote water meter installation points
1) The water meter should be installed in a place that is easy to access and read, free from exposure, freezing, pollution and mechanical damage.
2) The front end of the screw-type water meter should have 8~10 times the straight pipe with the nominal diameter of the water meter. Before and after the other types of water meter, there should be a straight pipe of not less than 300mm.
3) Rotary-wing water meters and vertical screw-wing water meters should be installed horizontally; horizontal screw-wing and volumetric water meters can be installed horizontally, obliquely or vertically according to actual conditions; when vertical installation, the water flow direction must be from bottom to top.
4) For the water supply system of life, production and fire fighting, if there is only one introduction pipe, the bypass pipe should be installed around the water meter.
5) An inspection valve shall be installed on the front and rear of the water meter and on the bypass pipe. The water meter and the rear valve shall be equipped with a water discharge device. In order to reduce the head loss and ensure the straight flow of water in the front tube of the watch, the front valve of the watch should be a gate valve. The household water meter in the house may not be provided after the watch maintenance valve and the special drain device.
6) Water meter wells should be protected from flooding and rain.
7) The direction of the water meter should be consistent with its type.
8) When the water meter may reverse, affect the metering and damage the water meter, a check valve should be placed behind the water meter.
9), the installation requirements of the hot and cold water meter are basically the same except for the different working temperatures. The maximum operating temperature of the hot water meter is 110 °C. If the hot water meter is installed in front of the boiler or heat exchanger, to prevent backflow, a check valve should be placed behind the water meter.
10) There are two ways to install the remote water meter: the remote water meter that only plays the role of outdoor meter reading is relatively simple to install, as long as the water meter output system is connected with the data display device (repeater) installed outdoors; Another way is to connect all the remote water meters of the entire building or the entire community to the cell management department through the repeater and the network controller, and perform unified management through the terminal devices.
