Working Conditions
Water temperature: ≤50ºC for cold water meter  
                                    ≤90ºC for  hot water meter 
Water pressure:   ≤1MPa or 1.6MPa optional
                  (10bar or 16bar option)

Each meter has one set coupling optional: 2pcs coupling, 2pcs coupling nuts and 2pcs washers.

Installation requirements
The meter should be installed in horizontal position with the direction of the flow as 
indicated by the arrow cast in the meter body with the register face upwards.
Pipeline must be flushed before installation.
The meter should be constantly full of water during operation.

Maximum Permissible Error
In the lower zone from Qmin inclusive up to but excluding Qt is ±5%.
In the upper zone from Qt inclusive up to and including Qs is: cold water meter ±2%.MID Certificated Multi Jet Dry Type Brass Water Meter
