Ranges indicated on the attached board, for DB/PDP flowmeters , are not contractual, but can be modified within
flow rate or diameter.
For DB IDP, minima flow rates have to be multiplied by 1,25.
Flow rates are indicated for PVC NP 10 pipes. In all events, the thickness and the exact interior diameter pipe have to be specified, so we may assure the specifications of the system
The loss of charge is the difference of pressure between upstream and dowmstream unrecoverable, create by the orifice. This loss of charge can be calculated on request.
The installation conditions are useful to warrant a coherent measure in the range of precision.
The straight pipe lenghts upstream of the orifice, undermentioned, are given for indication.
Number of D
07 Simple elbow at 90°or T (flow rate by one branch)
17 2 elbows at 90°in 2 different plans
07 Reducing from 2 D to D on lenght 1,5 D to 3 D
07 Valve completly open (type membran valve or ball valve)
The straight pipe lenght upstream depend to relation between intern pipe diameter (D), and the diameter orifice.
The exact lenght to respect for conserving the precision of whole measure are communicated after each case study.
The union nuts will be center with the flange of fixation as precisely as possible. The union nut arrest boards should be of the same diameter than intern diameter of tube, to avoid perturbation in liquid flow.
On resquest, we can deliver union nuts, flanges and screew.
