Inert Gas Flow Meter

Main usages:
Designed for timesharing electricity metering of new or reconstructed single-phase users. With prepayment function, it is particularly suitable to solve payment-collecting difficulties in residential area, organization, factories, mines and schools excite is preferable in promoting the management level at demand side, inducting the users to better power consumption style to improve power efficiency and electric sources collocation.

Main Functions
1.Both-way electric energy metering. Provides precise positive-negative active energy metering and one-way accumulating. Used for power metering and advance purchase of AC single-phase current rated.
2.Advance purchase quantity, preset maximum load-limit and IC card password. IC card transfers data and realizes data including total consumption, remaining quantity, accumulated quantity and total purchases etc.)backward reading.
3.Storage of leave-factory serial number, meter constants, initial data and the user's name and address etc..
4.Alarm and switch off when overload. Alarm at low remaining power to remind user of timely purchasing.

Main Characteristics:
1.High accuracy and import special metering chip. High accuracy, sensitivity and reliability, wide overload endurance, low power consumption, small volume and light in weight; easy installation, convenient auto-control and function expanding.
2.Long service life. With SMT technology and world famous, long-life components employed, its accuracy is not affected by frequency, temperature, voltage and higher order harmonics. Random installation location. No adjustment is needed if it leaves the factory as complete machine. Checkout period can be extended. Hence the workload of Watt-hour Meter testing and checking-out of electric departments is considerably reduced. Obviously better reliability than its similar.
3.Stable operation. Better stability for its wide range working voltage.
4.LED display, bright and clear prevent counter data from Losing at any times.
5.Single-phase,3-phase and multi-functional prepayment Watt-hour Meter can share a single electricity supply system.
6.With meter reading card and a portable computer, once about 1500 meters can be read.

How Does A DW Series energy meter using iot Work?
Acrel ADW Series IOT wifi enabled energy meter has two solutions to work. First, it can be connected to the gateway through RS485, and then the gateway uploads the data in the meter to the IOT cloud platform through 4G signal. The client can monitor the data in real time through PC or mobile APP. Solution 2 is ADW300 directly upload the data in the table to the IOT platform through 4G/WIFI signals, this solution does not need to pass through the gateway, more convenient installation.

K Power and K Power30 are systemic products used for flowering, fruit setting, and fruit growth in plants. They can be safely applied through both soil and leaves. The special plant growth regulators in their composition stimulate the plants resistance mechanisms. By shortening the internodes in plants, they promote the formation of healthier flowers and significantly increase fruit setting. At the end of the season, they help the plant store the phosphorus and potassium used during the winter period, supporting the formation of fruit buds for the next season.

It is a highly effective source of copper recommended for use in cases of advanced copper deficiency. Copper is one of the essential elements for the synthesis of chlorophyll, the green pigment responsible for photosynthesis. Chlorophyll synthesis plays a decisive role in the plants photosynthetic activity and consequently on yield. Copper also facilitates the formation of proteins and vitamins in the plant. In its deficiency, growth and development slow down, young leaves narrow and shrink, and in fruit trees, the tips of the branches dry out.
