For measuring the flow and volume of water with a temperature up to 30 °C or 50 °C, or warm water with a temperature up to 90 °C in the closed-circuit system with the full flow of the flux, and on the maximum working pressure up to 16 bar (PN16). Suitable for installation in the horizontal hoses (pipelines) with the counter directed upwards (H) and in vertical or horizontal hoses with the counter directed sidewards (V). Water meters are equipped with impulse transmitter (JS-NK) or adapted for installation of the transmitter (JS-NKP). In standard version they are equipped with five-barrel counter (IP65), antimagnetic protection SN + and brass housing. Possible operation of water meters in the systems of remote readings transfer.
