INSTALLATION REQUIREMENTS

1. Flostats can be installed in any orientation.

2. A vent is fitted on the pressure housing on the top of the diaphragm to allow simple removal of trapped air on liquid

Flostats on start up (when installed in horizontal pipework).

3. If possible, the Flostat should be installed with five diameters of straight pipework upstream, and three diameters

downstream. (These dimensions are reversed for Type B models). This gives the flow measuring orifice the required

working conditions.

APPLICATION EXPERTISE

Flostat equipment has been manufactured by Platon for over 30 years for many different applications. Apart from provid-

ing sizing information for different process conditions, alternative designs are available to suit specific requirements.

Please provide full application information for any enquiry, particularly specifying:

Pipeline Size

Flow range required

Fluid type, SG and viscosity if unusual

Fluid temperature pressure

Required body and diaphragm materials

Flange type required

For special options, please specify if scale plate or factory preset flowrate required. For gas flows, advise whether Type A

or Type B suits the pressure conditions best.

For lower flow rates (down to 2cm³/min), please consult leaflet DS1511 describing the Flostat Type MN.
