Find out what the JS90-NC flow transducer (DN15–20) has to offer

The JS90-NC is a Polish-made, mechanical, single-jet flow transducer designed for split heat meters. The device is used to measure the volume of water at temperatures up to 90°C in closed systems with full flow, at a maximum operating pressure of 16 bar (PN16). The flow meter is designed for installation in horizontal pipework with the counter facing upwards (H) or to the side (V), as well as in vertical pipework with the counter facing to the side (V). It is equipped as standard with a pulse transmitter (NC), a five-drum counter with IP65 protection rating and a brass body. The design of the device ensures resistance to external magnetic fields and high stability of measurement parameters. The transmitter is recommended for cooperation with the FAUN electronic totaliser. By using the JS90-NC flow transducer, you gain:

Measurement reliability thanks to compliance with MID metrological requirements

Measurement accuracy in accordance with Class 3 of EN 1434

Capable of operating at a working pressure of up to 16 bar

Resistance to tampering thanks to anti-magnetic protection

Clear and easy-to-read display thanks to the five-digit counter

Protection of the mechanism against malfunction by locking the counting mechanism at angles greater than 360°

Stable and precise measurement thanks to the application of a double-sided bearing rotor

Can be installed in various orientations (horizontal and vertical), offering greater installation flexibility

Preparation for the check valve installation thanks to the body’s adapted outlet connection

Compliance with the MID measuring range:_qi/qp = 1:50 (H); 1:25 (V)
