SET: JS hot water meter, type JS90-02 DN15 (1/2"), Q3=1.6 m3/h, R100, Tmax: 90°C, L=110mm, connection GZ3/4" + NAXOM-OP-04-1a-U81614 radio module 7A-3161BXB-AF6

Professional single-jet water meter for hot water installations

The single-jet water meter JS90-02 DN15 is an advanced solution for measuring hot water flow. Equipped with the NAXOM OP-04-1a radio module, it enables remote reading.

Technical parameters and measurement performance

The device operates with a continuous flow rate of Q3 = 1.6 m³/h. Accuracy class R100 ensures precise measurement across the entire operating range.

Maximum operating temperature 90°C. Installation length 110 mm and connection GZ 3/4" (external thread) ensure compatibility with standard hydraulic installations.

Application and installation compatibility

The water meter is designed for installation in hot water systems with a nominal diameter of DN15 (1/2"). The radio module NAXOM OP-04-1a U81614 enables transmission of measurement data.

Structural advantages and ease of installation

The compact design with dimensions 0.08 × 0.07 × 0.11 m and a weight of only 0.6 kg facilitates transport and installation even in hard-to-reach locations. The single-jet architecture reduces flow resistance and increases resistance to mechanical impurities present in the water.

The radio module is factory-installed and pre-programmed (SM profile), eliminating the need for additional configuration after installation. Threaded connections GZ 3/4" ensure a leak-tight connection to the installation using standard hydraulic components available on the market.
