RUBIN MeiStream, MeiStream Plus Cold water

ApplicationsRUBIN 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.

Features Wide measuring range

Measuring units can be replaced

Universal installation (MeiStream)

High overload capacity

Can be retrofitted with non-reactive modules for

remote readings

With MID approval

Your benefits Your benefits

Range

Turbine meters with dry-type registers, IP 68 SVGW certification Type examination certificate according to Directive 2004/22 EC Powder-coated grey cast iron housing with flange connections acc. to EN 1092-1 Maximum temperature 50 C Nominal pressure PN 16 Replaceable measuring unit For updating with non-reactive HRI modules or optoelectronic pulsers

MeiStream: The meter can be installed in horizontal, vertical or inclined positions. The meter head must, however, face upwards or to the side. It requires no inlet path

The MeiStream Plus is for horizontal installation only and requires an inlet path of 3 x DN

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 reducersThe 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 Q3 of the meter.

Inlet lengthFor MeiStream Plus 3x DN.

Mounting heightRUBIN 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 thatthere is adequate space above the meter for removal.The for horizontal installation only RUBIN MeiStream Plus is explicitly for horizontal installation only.

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

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