NOVOPRO LV-4T Multi-Tariff Hot Water Meter with Temperature Monitoring

What it is and why it matters

Novopro LV-4T is an electronic hot water meter that measures not only water volume but also water temperature. It helps you track the actual quality of domestic hot water supply and keep temperature-based records for further analysis.

Who it's for

• Apartments with centralized hot water supply where water temperature may fluctuate.
• Owners who want to see the real water temperature and keep temperature-zone statistics.
• Replacement for a standard mechanical meter (please check your existing metering node and required fittings).

How temperature-based registers work

• The meter stores the total hot water volume (GV) and keeps separate registers V1–V5 by temperature zones.
• It also calculates "Corrected Volume" (CO) using the formula from the passport: CO = 0.7·V2 + 0.8·V3 + 0.9·V4 + 1.0·V5.
• Important: billing and acceptance of specific values depend on your utility provider. In many cases you submit a single reading — the total volume (GV).

What's in the box

• LV-4T meter — 1 pc
• Passport/user instructions — 1 pc
• Packaging box — 1 pc

Note: union nuts/fittings, shut-off valve and a strainer may be required separately — selected to match your installation.

Optional installation and utility registration in Kyiv (priced separately)

Mastergaz can install the meter and help prepare/submit documents for utility registration in Kyiv. Service cost and fittings are calculated separately based on site conditions.
