Water Meter types
Combinations of connection, size, overall length and nominal flow – see tables below
The meter is available in versions for cold and hot
water respectively. The version is determined by the
country code, comprised in the type number, which is:
8XX for cold water
7XX for hot water.
*)
Note! Non-return valve is not possible because of the short overall length
**)
At flows above ’Maximum cut-off’ measurement continues corresponding to a constant flow at this value.

According to OIML R49 maximum pressure loss at Q
3
must not exceed 0.063 MPa (0.63 bar).
At Q
4
this results in a pressure loss of max 0.1 MPa (1 bar).
