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 car's water meter is just normal at what degree!: The circulating water vehicle is flowing in the high-pressure container, so when the engine can reach 110 degrees or higher, and the general alarm temperature between 115-120 degrees, this is because the high temperature can better maintain the engine cylinder body energy to help fuel.

Q:How can water gauge be installed on cast iron pipe?: According to the cast iron pipe is a large-scale water meter water meter, water meter diameter is more than 100mm for flange connection, meter mating flange 2, both ends of welding tube, making the sleeve and flange cast iron pipe welding tube connected to a good amount of water, length of the plus ends of casing (casing mouth), cut the cast iron pipe two the sleeve flange on the cast-iron pipe with good water, in the adjustment of casing pipe and cast iron pipe gap can be cracked.

Q:Does the water meter battery affect the water meter?: Intelligent IC card, mechanical water meter or intelligent remote mechanical water meter or intelligent water meter, ultrasonic water meter, electromagnetic water meter and so on

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:Do you know the working principle of dry water meters?: The water meter is divided into a wet type water meter, a dry type water meter and a liquid sealed water meter according to whether the counter is immersed in water.

Q:Card inserting water meter and method of use: Users to sell water, open an account, buy water, and receive a user card.

Q:How do you calculate the water meter inversion?: In short, the problem of water table rotation, although the national standard says that the water meter rotation within a certain limit is allowed, but the inverted water meter is completely uncontrollable. At present, only control to avoid the occurrence of water meter rotation, such as the installation of exhaust valve and check valve, so as to maximize the water meter to avoid rotation.

Q:How to use the card water meter?: IC card water meter working process is as follows: the amount of IC card into the water meter IC card reader, after the microcomputer module identification and download the amount of the valve open, the user can use water normally. When the user uses water, the water sampling device begins to collect the water consumption and converts the required electronic signals to the microcomputer module for metering and is displayed on the LCD display module. When the user's water amount drops to a certain value, the PC module carries out the sound alarm, prompting the user to pay the card to buy water. If more than the amount of water, the microcomputer module will automatically shut off the electronic control valve, cutting off the water supply. Until the user inserts the IC card that has been paid, restart the valve and start the water supply.

Q:The water meter is too big: Water pump pumping from the table, resulting in accelerated flow of water before the table, forming a relatively jet phenomenon, affecting the normal measurement of water meters

Q:Why should the water meter be horizontally installed?: Experts say, many users in order to save money or limited installation position, the water meter import and export pipe length is not enough. The correct installation is 15 mm caliber water meter, upstream of at least 150 mm downstream straight pipe, there should be at least 75 mm straight, otherwise it will because of the flow of "full of twists and turns and affect the measurement accuracy of water meter. In addition, the tap water, such as mixed air, excessive impurities and dirt from the pipe wall, will affect the accuracy of water meter measurement
