Platon Automatic Flow Controller

DS1531

ENQUIRIES

When placing an enquiry, please give all possible details as the

manufacturers have great accumulated experience in this spe-

cialised field and could contribute valuable guidance. Certainly

do not omit to specify the following:



Pipe Size



Preferred Materials and Connections



Control Setting and if adjustment required



Pressure conditions upstream and downstream



Fluid including SG and viscosity if unusual, with

temperature

CALIBRATION

For permanent and accurate control, it is only necessary to

ensure that the available pressure does not fall below the

Threshold Value which is the minimum required to provide

the control force and to overcome friction losses (P1-P3).

INSTALLATION

Each Flostat is calibrated with a straight approach pipe and

spring housing vertical. To reproduce the factory calibration

precisely, the installation should be similar, however, the fric-

tion with the butterfly spindle at other attitudes is extremely

small.

The Flostat should be orientated so that sludge does not accu-

mulate in the pressure responsive housing. With liquid flows, it

is desirable that the controller does not fill with air when liquid

flow stops.
