Oil and gas processing, water and wastewater treatment, and other industries that utilise chemical injection or additive monitoring in their product processing and operations will find the FLT93 Flow Switch Series from Fluid Components International (FCI) provides a highly reliable and rugged solution for verifying chemicals or additives are being injected, and ensuring injection pumps and feeders continue to operate.

fci-flt93-chemical-injection-hiThe advanced FLT93 Flow Switches are suitable for flow detection of liquids or gases, and are available in several wetted materials for compatibility with virtually any fluid.

It is a dual-function instrument capable of monitoring and alarming on both flow and temperature in a single device. Dual 6A relay outputs are standard and are assignable to flow or temperature.

FLT93 Flow Switches can be specified in either insertion or inline styles for installation in pipe and tube diameters from 0.25 inch and larger.

For monitoring chemical and other additive injection flow in small line sizes, the FLT93L model is an ultra-sensitive, inline-type flow switch that can detect liquid flow rates as low as 0.015 cc/sec and gas flow rates down to 0.6 cc/sec.

The FLT93S and FLT93F models are insertion types, and are the solution for liquids and gases in large diameter pipe sizes, respectively.

For sanitary processes, the FLT93C model provides 20Ra electro-polished 316L stainless steel wetted parts and tri-clamp sanitary flanges to meet the requirements in the food, beverage and pharmaceutical industries.

FLT93 Flow Switches utilise thermal dispersion technology, which has no-moving parts to foul or clog, and requires no routine maintenance. They also have long service life.

The electronics are housed in a NEMA 4X/IP67 rated aluminum or stainless steel enclosure to deliver outstanding durability and reliability under the harshest process conditions.

As further testament to this reliability, the FLT93 Series is SIL 2 compliant and carries a three-year warranty. Their superior temperature compensation assures no false trips should fluid or ambient temperatures change.

FLT93 Flow Switches feature a universal 24Vdc/85V-265Vac power supply, temperature service up to 454°C and a broad selection of process connections, including compression fittings, flanges, and packing glands.

Agency approvals and certifications include: FM, FMc, ATEX, IECEx, Inmetro and EAC/TR CU for Div.1/Zone 1 areas, CE, CRN, PED, and RoHS compliant.

FCI offers a broad range of flow switch products to meet a wide range of performance and application requirements.

FCI flow switches are rugged, reliable and repeatable to ensure continuous operation and long service life in industrial applications. An extensive selection of flow element materials, process connections and enclosures are available to ensure compatibility and easy installation in your process.
