RUBIN MeiStream,

MeiStream Plus
Cold water

Applications
RUBIN MeiStream and MeiStream Plus water meters operate according to the turbine blade flow measuring principle and are
designed for high-volume water measurement. The complete modular and housing system covers all areas of water supply
management. Meters can be retrofitted with pulse and data interfaces for mobile or stationary remote measurement.

Optoelectronic pulsers

• IR reflex light barriers to EN 50227 as a plug-in version

• Non-reactive optical tap
• Cable length 3 m
• Ambient temperature -10 - 70 °C, IP 68

Technical data:
- Power supply 8.2 VDC
- Switch current (actuated) ≤1.2 mA
- Quiescent current (non-contact) ≥2.1 mA
- Forwards and reverse flow detection is built in by means of an additional current threshold at 1.5 mA. With forward flow, the rising
pulse edge thus has an additional current threshold of 1.5 mA. With reverse flow, the current threshold lies on the falling edge of the
pulse.
Forward flow: Reverse flow:

- Pulse length is dependent on the flowrate and at meter standstill a continuous pulse is possible.

Installation notes
Nominal sizes: pipes, meters and pipe reducers
The choice of the nominal meter size should not automatically be based on the nominal size of the pipe. The decisive factor is the hig-
hest flowrate that occurs continuously in the pipe - this determines the nominal flowrate Qn of the meter.

< 8° < 8°

AM066243a

Mounting height
RUBIN MeiStream / MeiStream Plus meters have exchangeable velocity measuring units which can be tested and calibrated independ-
ently of the housing. For this purpose, the old units are removed upwards. When designing the installation, it is important to ensure that
there is adequate space above the meter for removal.

Installation position
Meters must not be installed upside-down as then the metrological approval requirements will not be met.

Electrical installation
Electrical cables and installation must be carried out by a specialist in accordance with legal requirements.
