Automatic Tank Gauges – ATG Control Panels

The most frequent level instrumentation task is level control and limit level switching whether if the measurement medium is liquid or solid. This is the reason why SMARTFLOW focuses on level switches in addition to the level transmitters.

SMARTFLOW supplies the instruments that offer reliable level control and limit level switching solutions for most media from potable water to sewage, aggressive alkalis and acids, or free- flowing, powdered, bulk or granular solids. Thanks to this very wide level switch selection we are able to provide suitable instruments for most level instrumentation applications.

Most of our level switches have explosion-proof versions (in accordance to ATEX and/or IEC Ex). Moreover we offer suitable solutions for special requirements, for example the ship-building industry with a need for Germanischer Lloyd (GL), Det Norske Veritas (DNV), Bureau Veritas (BV) or SIL approvals.

Strainer & Air Eliminators

Smartflow offers basket type strainers for variety of installations and conditions and designed for straining and filtering of wide variety of fluids.

As unfiltered liquid enters the strainer, will directly pass through basket in which almost all impurities are trapped into the basket and only clean liquid will pass through to the outlet of the strainer. Advanced dynamic flow and large filtration area elements ensure low pressure drops and reduce maintenance period. Also, it is prevented by “O” Ring seal between basket flange and strainer internal flange, as well as retain position of basket even in case of reverse flow.

Basket strainers are normally installed before the measuring devices like Positive displacement meter or turbine meter which increases accuracy of the measuring devices.

We offer basket type strainers from 11/2” to 16”size with flow range up to 800m3/hr for pressure range up to 200 bar & design as per ASME Section VIII div I latest edition. We also offer duplex and jacketed type strainers.


Air Eliminators

Smartflow also offers Bulk Plant Air Eliminators for variety of installations and conditions and designed for separation, elimination of air from main product.

Positive displacement meter of turbine meter, is a volumetric measuring device, cannot differentiate between liquid, air and vapour. So when liquid enters with air or vapour into this measuring devices, it will contribute the measurable error. Large amount of free air or vapour entrapped in the piping system, not only compromising meter accuracy but also lead to over speeding of meter and creating excessive wear or unit failure to ensure accurate liquid.

Measurement is necessary to remove all air from the system before entering into the measuring devices. Hence bulk plant air eliminator is installed before the meter for accuracy of the measurement devices.
