Main Features and Selection Methods of Electronic Remote Intelligent Water Meters
Electronic remote intelligent water meter is composed of ordinary mechanical water meter plus electronic acquisition and transmission module. The electronic module completes signal acquisition, data processing, storage and uploads the data to the repeater or hand-held meter reading device through the communication line. The meter body adopts an integrated design, which can record and save the user's water consumption in real time. Or directly read the current cumulative number. Each water meter has a code. When the smart water meter receives the meter reading instruction, it can immediately upload the water meter data to the management system. The editor of the remote meter reading system will introduce it to you.
The selection of the water meter should first consider the working environment of the water meter: such as water temperature, working pressure, working time, measurement range and water quality, etc. to select the water meter. Then, the diameter of the water meter is determined according to the design flow through the water meter, so that the pressure loss of the water meter is close to or not exceeding the specified value. Under normal circumstances, when the nominal diameter is not greater than DN50, the rotor type water meter should be used. When the nominal diameter is greater than DN50, a screw-wing water meter should be used. When the flow rate of the water meter varies greatly, a double-type water meter should be used. Wet water meters should be preferred in interior design.
There are two ways to install the electronic remote smart water meter: the electronic remote smart water meter that only plays the role of outdoor meter reading is relatively simple to install, just connect the water meter output system to the data display device (repeater) installed outdoors. Another way is to connect all electronic remote smart water meters of the whole building or the whole community to the community management department through repeaters and network controllers and conduct unified management through terminal equipment.
When the direct-reading electronic remote transmission smart water meter gradually overcomes its own disadvantages of difficult process and high precision requirements, it enters the mature stage. The pulsed electronic remote transmission smart water meter has already entered a very mature period in terms of product reliability, product manufacturability, product application specifications in engineering, and user awareness. With the development of the automatic meter reading market, the pulse-type and direct-reading electronic remote-transmission smart water meters will change from opposition to unity, and from exclusion to complementation.
