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. Rotor-type 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 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. Maintenance valves should be installed on the front and back of the water meter and on the bypass pipe. The water meter and the rear valve should 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. The direction of the water meter should match the type of the water meter. When the water meter may reverse, affect the metering and damage the water meter, a check valve should be placed behind the water meter.
7. 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; One way is to connect all the remote water meters of the entire building or the entire cell to the cell management department through the repeater and the network controller, and perform unified management through the terminal device.
8. Installation requirements for hot and cold water meters are basically the same except for different working temperatures. The large 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, a back check valve should be provided behind the water meter to prevent backflow.
The installation skills of the intelligent remote water meter will be introduced to you. We must install it in conjunction with the actual operation.
