Description
The meter fills the gap between apartment vane meters and large turbine meters. The R315 range is set by the MID directive (EN 14154, OIML R49, ISO 4064) and is achieved through a modular inlet channel and measuring chamber, precise manufacturing, double-sided support of the vane and adjustment of the characteristic without a bypass channel. A low starting threshold registers small flows, so the meter data can be used to build a water consumption profile of the building. According to the manufacturer, straight pipe sections before and after it are not required, and installation is horizontal with the register facing up. The IP65 version works with optical and inductive modules, NKOP is prepared for reed and optoelectronic sensors, and IP68 with a sealed register and #UTIP connector is intended for inductive modules and wells that can flood. The register is protected against turning beyond 358°, and radio, M-Bus and pulse modules provide remote reading.
How to choose
The size is determined by the diameter. JS 50 has DN50 and Q3 25 m³/h, JS 65 DN65 and 40 m³/h, JS 80 DN80 and 63 m³/h, JS 100 DN100 and 100 m³/h. The face-to-face length per DIN 19625 or ISO 4064 is from 270/300 mm for DN50 to 360/350 mm for DN100, and 300 mm for DN65, with flanged connection. For large flows with a variable pattern, see the combination MWN/JS-S meters, and for individual large draw-offs the MWN Nubis turbine meters.

FAQ
What water temperature and pressure is JS Impero designed for?
Versions up to 30 °C and up to 50 °C are available, with a maximum working pressure of 16 bar.
Are straight pipe sections needed before the meter?
The manufacturer states that they are not. Installation is horizontal with the register facing up.
Which register version should be used for a well?
IP68 with a sealed register and #UTIP connector, intended for inductive modules and harsh conditions, including wells that can flood. Inductive reading does not depend on the magnetic field.
Can the readings be taken remotely?
Yes, through radio, M-Bus and pulse modules. The NKOP version is prepared for reed and optoelectronic sensors.
