Large diameter ultrasonic heat meter

The selection of water meter should first consider the working environment of water meter, such as water temperature, working pressure, working time, measuring range and water quality, etc., and then determine the diameter of water meter according to the design flow through the water meter to produce the pressure loss of water meter close to or not exceeding the specified value. In general, 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, the spiral wing water meter should be used; when the flow rate of the water meter changes greatly, the compound water meter should be used. Wet type water meter should be preferred in interior design.
When the water consumption is uniform, the nominal diameter of the water meter should be determined according to the design flow rate per second not exceeding the common flow rate of the water meter. When there is a 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.
There are two ways to install the remote water meter: the remote water meter which only plays the role of outdoor meter reading is relatively simple, as long as the water meter output system is connected with the outdoor data display device (repeater); the other way is to connect all the remote water meters of the whole building or the whole community to the community management department through the repeater and network controller, and through the terminal equipment system 1.
