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:The total water meter and the total value of the water table vary greatly
This can be self-examination: all the taps are closed, to see whether the total water meter is still walking. You can also ask the staff of the water company to check. They have special equipment. Two is to check the house of the water pipe, there is no previously connected bypass pipe, forgotten.
Q:How do you connect the water meter with the PPR tube?
PPR pipe fittings, there is no set of silk said, you this statement may be the local saying. There are two kinds and four kinds of conventional direct silk thread parts:Outer wire tap (as follows)The wire connecting (below)Outer filament direct (as follows)The wire directly (see below)Specifications, products or external packaging are marked, please pay attention to must buy silk pieces, because it is more expensive than pure plastic oh.
Q:What's the structure of the valve before the water meter?
The valve is gate valve, the valve core and the dam gate principle is same, the gate heart rises, the water flows out the gate heart to be lower, the water is smaller, until closes!
Q:Household water meter sudden increase of about 100 tons of water, what is the matter?
To doubt the water meter, water festival to house all close all doors (including water switch off each toilet), observation of the water meter is in turn, do not turn to the house and that water tap water pipeline is no problem.
Q:How do you adjust the water meter?
In addition, the number of calls to the former water companies to respond to the situation will be more reasonable.
Q:Can you tell me the unit of measurement for standard water meter, ton or cubic meter?
Both are available. A ton is only a weight, and a cube is a sign of size.Because the proportion of water is 1g/c, is also very easy to work.
Q:Why is there so much water in the water meter?
It's not water! It is mechanical oil to prevent corrosion in table!
Q:The difference between rotary vane water meter and screw wing water meter
Rotor type water meter rotor type water meter is suitable for small diameter pipeline unidirectional flow measurement. Such as total household water metering caliber 15mm, 20mm specifications of pipe. The water meter is mainly composed of a casing, impeller measuring mechanism and a retarding mechanism, as well as indicator, has the advantages of simple structure characteristics.
Q:The new rotor type water meter, in dripping water, if the drip is very slow, for example, 10 minutes a drop, the water meter will turn? Do not know the reason, please do not answer, please explain the reason!
The new meter adds a cavity in the bottom case, and is connected with the water outlet, the middle with a soft diaphragm separated, and adding a valve at the outlet, when the outlet to drip out water, down to the deformation of soft membrane in the inlet pressure under the action when the water reaches a certain amount, drip proof device will open the outlet pressure, so as to drive the impeller to rotate to measure the effect process of water supplement is intermittent, measurement in the process of water leakage is intermittent. When the normal water valve, the sensor will follow the open, so that the water becomes a completely ordinary water meter.
Q:Why can the high level intelligent water meter be equipped with a check valve that can not prevent the water meter from idling?
The pressure fluctuations, because the water is a liquid, the physical characteristics shown in general is incompressible, but in the tap water pipe, pipe pressure is high, then the water will show some compressibility. In the tap water pipe, the pressure fluctuation is inevitable, and now we are using the water meter is a mechanical watch, in which water flow generated by the kinetic energy to drive gear, so as to achieve the purpose of water metering. When no water, the water pipe ends are connected in a certain amount of high pressure water are fixed; therefore, when the municipal pipe network pressure rises, the volume of tap water pipe after the table shrinks due to the increase of the pressure, this will have a trace of the water through the water meter, is generated; when the pressure is decreased, the table after the tube in the compressed water with low pressure and expansion, will also have a trace of the water through the water, the difference is this time reversal. As we all know, the general mechanical table in the water is in the drive gear, is turned upside down when the water is in progress under the drive gear reversal, the drag force of water phase is different, although the two head of the same amount of water, but reflected in the reading on the meter is very different. According to statistics, in the absence of air in the pipeline, the resulting water is very small, about 0.5-1m3/ months. Under normal circumstances, the water users will not pay attention to; at the same time, this is also the normal level of measurement results.
