PRESENTATION

Diaphragm is inserted between 2 flanges in the main duct. The differential pressure is transmitted to the exterior via 2 pressure ports on each diaphragm face. This pressure is proportional to the flow rate square in circulation inside of the duct. A flowmeter, mounting in derivation allow a direct reading of the flow rate. To obtain a strictly proportional to the main flow rate, a BORDA injector is insert before or after flowmeter.
This flowmeter can be replaced by a counter, allowing a totalization.
Orifices can be only delivered in stainless steel 316 L, or with pressure ports directly on steel or stainless steel. Their accuracy is 1%, diameters are from 50 and 60 mm. We supply flowmeter with special graduation for derivated measure on all existing diaphragm, only if specifications are given before graduation.

SCALES

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.

PRESSURE LOSS

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.

INSTALLATION REQUIREMENTS

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.

FIXATION FLANGES

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.
