Bermad Sensus Meiastream Plus Mechanical Water Meter for Potable Water (40-150mm Flanged)

The MeiStream Plus is one of the most reliable and high-accuracy mechanical water meters available. With a number of industry approvals (OIML R49, Australian Standard AS3651.1, MID Pattern) and great capacity for customisation, this meter is the ideal choice for a wide range of applications.

MeiStream Plus conforms to the extreme low flow requirements of metrological class
C meters, while allowing considerably higher flow rates than current single jet bulk water meters. Furthermore, this is achieved with reduced pressure loss and less sensitivity to particulates in the water.

Due to a ball-shaped hub the turbine locates itself in a free-floating position between the two bearing stops. As the minimum flow rate is reached the turbine rotor lifts firstly vertically and thereafter axially into a frictionless positionwith no radial or axial forces on the bearings.This free-floating rotor position is maintained up to extreme overload conditions, thus ensuring maximum metrological sensitivity throughout the flow range. The rotor blade design is the result of many years of research and development ensuring long-term durability and a constant metrological performance over a wide flow range, thus providing optimum revenue generation over the extended life of the meter
