Woltex WE Counters turbine

1.1 Meters turbine Woltex WE... (hereinafter the counters), manufactured at the plant of IHOP Lapse (France), designed for measuring the volume of cold potable and technical water (temperatures up to 50 °C) or hot water (temperature up to 130 °C) municipal or main water supply, and also the industrial sector.

1.2 meter equipped with an output for connection module SOWIE for remote data transmission (see Section 7), which allows use counters:

• as part of a system for remote data acquisition and processing (ЕverBlu, AnyQuest, M-Bus);
• as part of a system of monitoring and control of technological processes;
• as flow meter thermal energy (hot water meters).

1.3 Meter may be installed in wells and flood-prone areas (see item 2.6. and 4.3).

2 MAIN TECHNICAL AND METROLOGICAL CHARACTERISTICS

2.1 Metrological characteristics of the counters correspond to the class In accordance with DSTU 3580-97 when installed in any position.

2.2 cold water Meters Woltex... WE are certified to operate on two nominal costs Qn: normal (N), characteristic of the water meters of a given diameter, and high (G), characteristic of water meters nearest larger diameter (see Table 2-3).

2.3 Technical and metrological characteristics of counters are shown in tables 1-5.
