ROBITON PM - electricity meter in every outlet!

ROBITON PM - electricity meter in every outlet! Absolutely wonderful appliances. These are outlet electricity meters or household wattmeters ROBITON RM-1, RM-2. Unique instruments allow you to measure with high accuracy the amount and cost of electricity consumed, the power of the connected load, and the PM-2 also measures the voltage and frequency of the mains, the current consumed by the load and power, and takes into account the two-tariff day-night payment system. At the same time, the price of devices is such that it makes them affordable for any home.

However, first things first!

Energy meter - ROBITON PM-2 wattmeter Designed to measure electricity consumption by household appliances. In PM-2, you can enter the price of kilowatt hours and find out the total cost of electricity consumed by the connected electrical appliance, for example, for a month.

Since two price modes are implemented (there is a setting of days of the week and time of regime change), this model is suitable for round-the-clock measurement of energy consumption of household appliances.

For example, I connected an Ariston electric instantaneous water heater to RM-2, which has two heating elements of 1.25 kW each, in order to know how much electricity is consumed by hot water.

New knowledge has helped to take a fresh look at this issue. And the temperature on the Ariston thermostat is now set based on the real needs for hot water. You need to take a shower - we heat the water to 50 - 60 degrees. This is enough. And 40 degrees is enough for washing hands.

The function of measuring voltage is useful in the house, since it can be either high or low.

The PM-2 power meter is equipped with a large single-color LCD display, three control buttons and a “reset” button for quick data cleaning.

Displayed parameters: time, network voltage, current and power consumed by the appliance, amount of consumed electricity (kW * h), AC frequency (Hz), efficiency of the connected device (power factor), total operating time and cost of consumed electricity.

Electricity consumption meter - wattmeter ROBITON PM-1 is the younger brother of the PM-2 device. It is smaller in size. The device allows you to set the price of kilowatt hours and calculate the cost of electricity used by electrical appliances.

PM-1 is suitable only for single tariff metering. The PM-1 wattmeter is equipped with a small LCD display and three control buttons.

Displayed parameters: power of connected load, quantity of consumed kW / h, total cost of consumed electricity and price of one kW / hour.

The device is simple and convenient.

The ROBITON PM-1 power meter is conveniently used to control the power consumption of various household appliances, such as heating devices in rooms, a kettle, a washing machine, a heated towel rail, etc. The device is the smallest and the cheapest of the line. Its cost today is 798 rubles.

Why do we need these devices if every house has a regular electricity meter?

To select the optimal mode of operation of specific electrical appliances in the house to pay less money for electricity. To know the actual consumption of the appliance, which often differs from the one declared by the manufacturer (my BOSCH kettle with the claimed 1.6 kW eats more than 1.8 kW).

Especially relevant is a wattmeter with a counter in country houses and cottages where there is no gas heating and hot water supply.

For example, in my country house a power meter showed that convectors in the entrance group (entrance to the house) and in the utility rooms consume "excess" electricity. A decrease in the temperature they maintained by only 2 degrees gave tangible savings in money.

In the same way, the optimal operating mode of the storage water heater and the washing machine was chosen.

You can, of course, buy one PM-2 device and measure the network parameters and equipment consumption with it. But, if measurement at once of all parameters of the power supply network is not required, it is better to have several wattmeters, with energy-intensive electrical appliances constantly connected to them.

This will allow you to control and adjust energy consumption and rationally spend money on electricity. Indeed, if you see clearly where the money is flowing, you are unlikely to turn on the water heater 80 degrees to wash your hands several times a day in warm water.

Curious to know the power consumption of computer equipment and a TV. So I found out that my laptop, when turned on, consumes about 20 watts. However, during on / off, its power consumption increases to 80 watts. The power consumption of the computer is also increasing in resource-intensive programs, such as photo-video editors.

Every zealous or simply curious owner of a wattmeter will like it!

But, on this the use of a home wattmeter is not exhausted. A wattmeter will provide very important assistance in cases where the electric power allocated to the house is limited.

A wattmeter will help to measure the real energy consumption of energy-intensive home appliances in different operating modes. This is necessary in order to know how much and what can be turned on at the same time, so as not to cause network congestion and disconnection of the input machine.

With insufficient allocated power, it is convenient to use network load optimizer OEL-820. In this case, the wattmeter will help to distribute the load between the OEL-820 units to minimize the total power consumed by the household.

A good article, everything would be fine if there was information about other similar "electricity meters" with price comparisons. And so ... mostly advertising for a particular product.

Here is another area of application of this device - control of energy consumption for lighting porches and courtyards. Now the residents of apartment buildings are literally furious because of the high accrual of ONE, somewhere they even set meters for each entrance, and then they bite with neighbors in the entrances: who burned the most.Here you do not need to install any fully functional meter - just in the dashboard on the ground floor, where the wiring for light bulbs in the entrance and at the entrance leaves, you can put a socket, screw the plug into the wiring and insert it through this mini-meter. I think this is convenient, takes up little space and an amperage of 16 A. And it will pull any lighting, even in a high-rise building. True, ONE because of this will not drop ((

Sergey, all this is good, but there is one small nuance - please answer this question: how long will this device stay in the entrance, if you put it, and leave? I think no more than 15 minutes. Or will you exhibit sentries who will serve around the clock? After all, they will lead away early! At one time, until the computer metering of electricity meters was established, they were stolen en masse, during the night they could completely “clean” a 9-storey building with 8 entrances. Now it simply does not make sense to steal them, since the stolen counter is nowhere to be used. As soon as you bring it to some distribution zone, they will tell you in a minute whose counter it is and where and when it was stolen. And then in the police you will write explanatory notes, where did you get the stolen counter. And you won’t even put it on a garage or country cooperative, since the chairman of the cooperative can collect all the counters and send them to the test with the same consequences. But such a mini-counter is pulled without any consequences.

VladimirI think installing such a mini counter in the stairwell is a good idea. So as not to be pulled, you can put it in the shield, which closes. I do not mean the enclosures of the switchboards, which can be opened with a screwdriver, but take and weld a small shield and close it with a normal lock. I very often met such shields in the entrances, very reliably, since they could not be opened quietly, and neighbors would come out to the sound of a hacksaw or a hammer.

MaksimovM, but a simple "numbered" counter that you can’t steal costs 650 rubles and you don’t need to fence the garden. Second-hand for technical accounting and verification is not necessary and costs free. By the way, all apartment counters, in the presence of common house accounting, can also be considered technical metering devices. What implies the optional sealing and verification. IMHO))

AlexeiWell, in principle, both methods are acceptable. And as for the optional verification, and especially the sealing of apartment metering devices, this can not be, even if there is a common house accounting. In the absence of seals, people immediately want to connect illegally. And does the energy supply company need additional problems in the form of underestimation? Even after one such case, the energy supply organization will oblige each tenant to install a certified metering device and seal it in order to exclude cases of theft of electrical energy.

MaksimovM, all the "underestimation" is scattered as ONE. It’s impossible to steal from a sales organization, it is possible to shift part of the costs to neighbors. It is assumed that each owner and sales organization have an agreement, and therefore an attorney and sealed metering device is available, but since the final calculation is carried out with the addition of ONE, I consider the presence of seals, etc. on individual metering devices not necessary. Well, except as a frighteningly-disciplining tool). We still have in some places metering devices for ODN, but their readings are not taken into account, and ODN are calculated from common houses - accounting at the entrance of the house.

Hello everyone, I’ll tell you frankly, I decided to put on an experiment once, I took and changed all the bulbs to energy-saving ones, the effect was just amazing - the light bill almost doubled ... but as always there is a fly in the ointment - apparently due to power surges, but I live in Moscow, the bulbs began to burn out one by one. He installed different manufacturers - both expensive and cheap, but all the lamps were energy-saving. To be honest, I decided to continue the experiment further - I found an LED lamp store on the Internet, looked at prices and characteristics, and decided, I installed LED lamps at home.
Gentlemen, I’ve been bastard for the second year, of the minuses, only one or two bulbs turned out to be defective, but they immediately changed them to me without any words, and as for “do not burn the light”, I completely forgot what huge energy bills are).

Everything would be fine, but ...
Energy consumption is measured in kW * h.
If your kettle consumes 1800 watts, and not 1600, then this only means that it will boil the same volume of water faster.
Efficiency and power factor are different concepts. Read at least Wikipedia. Show me at least one device that measures efficiency. I doubt that the devices also show a power factor. For simple housewives, his testimony is not needed, especially since we only pay for the active component of power.

Put LED lamps, insulate your homes with quality and we will give you happiness and energy savings.
