Why buy an induction energy meter: strengths and weaknesses

Electromechanical devices can still be found in old buildings of the Soviet era. a new generation of devices is significantly modified, however, they use the same operating principle. The design takes the form of a plastic box equipped with a viewing window. Through the glass you can see the rotational motion of the disk and the credentials of the electricity consumption.

The meter is equipped with 2 coils creating electromagnetic fields due to the passing voltage. Due to this magnetic flux is driven by the aluminum disk, which affects the wheels, displaying numbers. The rotational speed of the disc in the old electricity meters, as well as in new, depends on the volume of electricity consumption. This is displayed on the device performance.

Note!Obsolete induction unit is gradually coming out of a turn, although they are not without certain advantages.

Advantages of induction devices:

• reliability of the operation, a low percentage breakdowns;
• unlimited service life of electric power;
• sudden voltage fluctuations in the mains does not adversely affect the device;
• affordable price.

This embodiment has some drawbacks:

• in testimony often have significant errors;
• Device absolutely immune against theft of electricity;
• apparatus carries out independent electricity transmission readings (Self-propelled records without consumers).

The cost of electricity induction type ranges 750-3300 rubles.

Which is better to put in a flat electric meters accuracy class

Operation of any equipment is accompanied by some accounting errors with respect to indications. On what class the counter, it depends on the difference in rates. A tolerance of only a few percent of the actual consumption.

Devices for domestic purposes flats have a deviation within 2% on average. In practice, it appears as if the user had spent 100 kW of electricity, then the data displayed counter will be in the range 98-102 kW.

Note!The lower the accuracy (class) in the technical data sheet device, the less error occurs when registered electricity. These counters are much more expensive than others.

If you determine which is best electricity meters, starting from the index error, it is necessary to give preference to a Class 2 devices. On sale there are several versions of the device with a different percentage of error:

• 0,2-05%;
• 2,5%;
• 1-2%.

Features a selection of devices for accuracy class

Single-rate and multirate Electricity meters: price and features

The appearance on the market of electronic devices, the system consumed energy accounting data has significantly changed. After the installation of the meter in an apartment, you can now maintain records across multiple billing. Modern devices are able to maintain a 2-3 rate, and some models - and more.

How much are the counters for electricity: prices chetyrehtarifnyh devices:

device model	price, rub.
Energomera CE R5 102M 145 253295 J	2320
EKF Scat 105E / 1-5 (60) TOI4 10501	2775

The basis of the multi-rate meter is split time accounting. For example, power consumption of the daily count rate starts at 7.00 and ends at 23.00. Countdown night charging mode starts at 23.00 and ends at 7.00.

Useful advice!The cost of electric power consumed during the day, is significantly higher than at night. All energy-intensive inputs such as washing can be scheduled at night to save money.

Price of electricity meters day / night is much higher than conventional single-rate. But not all apartments have a significant difference between the cost of electricity during the day and night, so the cost of the purchase of multi-rate equipment can not be recouped. Before purchasing costs to produce cost estimates broken down by day / night and to compare them with the results of a single tariff.

If the economy reaches 35-50%, it is safe to perform the replacement of the meter in an apartment on multi-tariff, if the difference is only 100-200 rubles., That such an acquisition would be impractical.
