Flow Meter And Pressure Measurement Products

Temperature Transmitter

THERMOCONT field device incorporating Pt 100 sensor is 2-wire temperature transmitter with 4 … 20 mA analogue output or transmitter/indicator if equipped with a plug-in display. Intrinsically safe version of each model is available in ordinary or flame-proof housing. The measured temperature can also be transmitted by Hart communication.

Intelligent electronics and HART communication provides for remote programming, error monitoring and indication. The instrument is suitable mainly for temperature measurement of liquids in tanks and pipes and free flowing or lumpy solids, but temperature gauge for rooms is also available.

The PFA coated stainless steel probe makes measurement of very aggressive materials also possible. As special version of the unit a remote transmitter is also available which can be connected to a standard Pt 100 sensor through a simple 4-wire cable.

Air Eliminators & Strainer

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.

Density measurement – The STG is also able to measure two interface levels, spot density and perform density profiling throughout the liquid.

Level Switches

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.
