Find out what the JS-NK water meter has to offer

The JS-NK is a high-quality single-jet water meter designed to measure the flow and volume of cold water (up to 30°C or 50°C) and hot water (up to 90°C) through a closed system with full-flow operation, at a maximum operating pressure of 16 bar. Thanks to its hermetically sealed counter and rotation lock on the counting mechanism, it ensures accurate readings even under difficult operating conditions. The water meter’s design allows for installation in horizontal and vertical pipes, whilst the brass body and SN+ anti-magnetic protection enhance durability and resistance to external interference. By using the JS-NK, you gain:

accurate and reliable readings in accordance with MID metrological requirements

easy to read thanks to the five-drum, anti-fog display

stable and accurate measurement thanks to the application of a double-sided bearing rotor

protection against freezing and external interference

capability to integrate with remote reading systems

option for the installation of a non-return valve on the outlet connection
