U Series Meters

The calibratable energy meter can be used to acquire and bill active energy in industrial, household, commercial and building management applications.

Type approval and calibration allow for official billing of electrical energy to third parties. Relevant values are transmitted to data logging, billing and optimizing systems, as well as to building automation and control technology applications, by means of a pulse output, or via LON, M-Bus or L-Bus interface.

Installation itself is extremely simple because the meter detects connection errors, which are indicated immediately. Maximum convenience is assured by displaying active power, which provides immediate information regarding momentary circuit load. If more information about the electrical system is required, functionality is simply expanded.

Multifunctional Variant
With the multifunctional variant, the meter is also capable of displaying up to 26 additional measured quantities. As a result, voltage level, utilization of individual phases, reactive power component and the functioning of compensation systems can be evaluated at any time by simply pressing a button without any additional measuring equipment. Refer to the table for details.

Diverse Calibration Capability – Approved for Official Billing
The meters have national type approvals for D, AT, CH, CZ, and HR, and can be used for official third part billing in the respective country after initial calibration by a federally approved test authority.

In Germany, the energy meters can be supplied as calibrated variants (P1), and additionally with calibration certificate (P2), for official energy billing. In accordance with legal requirements, the calibration certificate may not show any measurement error. Initial calibration is carried out at Gossen Metrawatt's federally recognized EB8 test laboratory.

Scalable Functionality
The energy meter can be ideally matched to the measuring task – and the customer only pays for what it actually required.
