Remote water meter installation and selection

The remote water meter is composed of an ordinary mechanical water meter plus an electronic collection and transmission module. The electronic module completes signal acquisition, data processing, storage and uploads the data to a repeater or a handheld meter reading device through a communication line. The body is designed in one piece. It can record and save the user's water consumption in real time, or directly read the current cumulative number. Each meter has a unique code. When the smart meter receives the meter reading instruction, it can upload the meter data immediately. To the management system.
Remote Water Meter Installation Tips:
1. The water meter should be installed in a place convenient for inspection and reading, free from exposure, freezing, pollution and mechanical damage.
2. The front of the screw-type water meter should have a straight pipe with a nominal diameter of 8 to 10 times 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-wing type water meters should be installed horizontally; horizontal-wing type and volume-type water meters can be installed horizontally, inclinedly or vertically depending on the actual situation; when installed vertically, the direction of water flow must be from bottom to top.
4. For a water supply system that integrates life, production, and fire fighting, if there is only one inlet pipe, a bypass pipe should be installed around the water meter.
5. The maintenance valve shall be installed on the front and rear of the water meter and on the bypass pipe, and the water discharge device shall be installed on the water meter and the rear valve. In order to reduce the head loss and guarantee the straight flow of the water flow in the tube in front of the watch, the check valve should adopt the gate valve. The household water meter in the house may not have a post-watch maintenance valve and a dedicated drain device.
6. The water meter well should prevent flooding and rain. The direction of the water meter should be consistent with its type. When the water meter may be reversed, affecting the metering and damage to the meter, a check valve should be placed behind the meter.
7. The remote water meter is installed in two ways: the remote water meter only serving as an 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 in the outdoor; One way is to connect all the remote water meters of the whole building or the entire community to the community management department through the repeater and the network controller, and perform unified management through terminal equipment.
8. The installation requirements for hot and cold water meters are basically the same except that the operating temperature is different. 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, a check valve should be installed behind the water meter to prevent backflow.
Intelligent remote water meter installation skills will be introduced to you, we must be combined with the actual operation to install.
Remote water meter selection
1) The selection of the water meter must first consider the working environment of the water meter: if the water temperature, working pressure, working time, metering range and water quality are selected, then press the design flow through the water meter to generate a pressure loss close to the meter and Do not exceed the specified value to determine the caliber of the water meter. Under normal circumstances, when the nominal diameter is not greater than DN50, a rotor-type water meter should be used; when the nominal diameter is greater than DN50, a screw-type water meter should be used; when the flow rate of the meter varies greatly, a double-meter water meter should be used. The wet design of water meter should be preferred in interior design.
2) When the water is uniform, the nominal diameter of the water meter shall be determined according to the designed flow rate not exceeding the usual flow rate of the water meter. When there is fire flow, it is necessary to check the flow to ensure that the total flow does not exceed the maximum flow limit of the water meter.
