NB-IOT Water Meter DN15

The wireless water meter is composed of a wet base meter or a dry base meter, a collecting unit, a transmitting unit, a routing unit, a battery, and the like. Also apply the letest NB-IOT communication technology( Narrow Bandinternet of Things). Supporting low-power devices in the WAN cellular data connection, is the latest-generation of remote water meter. One of its remarkable features is that its comprehensive cost is very low, especially the installation cost, just like the ordinary mechanical water meter, no need to punch on the pipeline can be run. All debugging is done completely at the computer terminal.

Features

The reding is accurate, and the water meter accumulates water in real time to ensure that data is not lost.
Using NB-IOT narrow-band IoT communication, the signal has no dead ends,
The base meter and the wireless unit are separated, and the replacement of the base meter and wireless unit is simple and quick.
Remote valve control, water realizes remote valve control, and effectively realizes the payment of the fee.
Automatic timing meter reading upload data. Read data by setting time every day, automatically send
IP68 design, electrinic module and battery are IP68 which can be soaked in water for a long time to work.

Q: How to see the water meter, how to view the water meter?: Pointer type water meter: this kind of water meter is more common in a bungalow or an old building,The red pointer part is the decimal part, when the pointer from the extreme position clockwise direction up to a digit, you can read the use of tonnage. And so on, followed by a black pointer, ten, hundreds and thousands, read text as we watch the same readings can be. In the example above, we see a number of pointers between 5-6, ten bit pointers between 0-1, and 100, 000 pointer 0, then the table is 5 tons of water, because of its very is 7, so less than 6 tons of water, 5 tons of water is half the 10 tons of water. So, the ten pointer between 0-1, 100, 000 far, not in hand.Monthly water use, that is, this reading reduces the difference between readings.

Q: Will the glass of water gauge explode in summer?: Instead, in winter, water meters can be frozen and burst because the water is below 4 degrees and freezes after expansion.

Q: Must the new water meter be checked before use? Does the state expressly provide for it? In which regulation do you specify clearly?: After the new water meter is out of the factory, no husband has to confirm it, because the manufacturer of the water meter has obtained the permit for the manufacture of measuring instruments.

Q: The water meter doesn't move. The pump keeps beating. Why?: First, check the pump connection pipe whether there is a valve open, if there is no flow out, the water meter is not going.Second, if there is water flowing out of the pipe and the water meter doesn't go, it's probably the water meter is broken.Third, check the flow of water outflow, if large enough, it can be sure that the water meter is broken.Fourth, if the outflow of water less than the meter (don't know your water meter specifications) the starting flow, it should check the pump.

Q: Does the new water meter go slower than the old one?: Because of the current domestic water environment problems, China is basically using speed water meter, both at the speed of water flow to measure. Because the old water gauge will have sediment (scale), so the caliber will gradually become smaller, pressure will change in the same case faster!

Q: Is the check valve installed on the left or right of the water meter?: Should be installed at the water inlet of the water meter, and the distance between the water gauge and the water meter is at least 30 centimeters. At present, the picture gives the situation, the valve is too close to the water meter, may affect your home water meter count, and will make your home water meter faster, you may pay more, but how much will not be able to accurately say. It is recommended that both the check valve and the master switch be at least 30 centimeters apart from the water meter.

Q: How to use the card water meter?: Card type water meter usage: prepaid mode, that is, buy water first: water meter initial water availability is zero, the valve closed.

Q: What are flanged valves and flanged water meters?: The connecting way of valve and water meter is flange. The valve and water meter should be connected to the pipe to work properly. The common connection modes are thread connection and flange connection.

Q: How can a water meter steal water and a magnet?: There are different reasons for the change of electronic energy meter and mechanical watt hour meter in the strong magnetic field. The reasons for the malfunction of the mechanical ammeter are similar to those of the electronic water meter. The electronic meter is currently used in the way, under the condition of high magnetic field is generally due to the strong magnetic field to the magnetic core of the transformer in the power circuit of the electric meter is magnetized, electric power circuit failure, not working properly, the meter is usually followed by a black screen, or other abnormal function, not the normal measurement meter. However, the new national standard has obviously been noted above, for the new national network, smart meters in this area has been added protection, and for magnetic field interference will record event records
