AMS Instrumentation and Calibration has introduced a new precision flow/level/temperature switch from Fluid Components International (FCI).

Designed as an effective and highly reliable solution for a wide range of fluids and industrial applications, FCI’s newly redesigned FLT93 Series FlexSwitch is compliant with the European Union’s Restriction of Hazardous Substances (RoHS) Directive. Featuring new high-density surface mount technology (SMT) electronics, the environment-friendly FLT93 Series FlexSwitch now meets all EU restrictions on lead solder and five other toxic materials found in some electronic devices.

New design features of the FLT FlexSwitch include a state-of-the-art quick disconnect terminal block; entire electronics assembly firmly secured into an aluminium or stainless steel housing to improve vibration immunity in rugged plant environments; SIL2 rated for ultra-reliability, especially in demanding processes and plants; and Ex agency approvals FM, FMc, ATEX, IECEx, InMetro and EAC/TR CU.

Considered the process industry’s most advanced heavy-duty thermal dispersion technology flow and level switch in the world, FCI’s FLT93 features a multi-parameter measurement design based on more than 50 years of flow and level switch engineering and application experience, providing a rugged long-life instrument.

Found in continuous operation in demanding and critical process and plant environments, FLT93 switches are a preferred solution in oil and gas upstream and downstream applications, wastewater treatment, chemical operations, power plants, food and beverage, refineries, mining, metals and manufacturing among others.

The dual-function FLT93 switches can be configured for flow or level sensing, flow + temperature sensing or level + temperature sensing. A single FLT measures and monitors flow or level and temperature simultaneously with excellent accuracy and reliability. Dual trip points and 6A relay outputs are standard and assignable to flow, level or temperature.

FCI’s unique sensor technology built into the FLT93 switches, combined with FlexSwitch temperature compensation circuitry, provides users with superior performance capabilities. These include exclusive flow accuracy as precise as ±2% of setpoint velocity over ±28°C temperature range; repeatability of ±0.5% reading; level resolution of ±2.5mm; repeatability of ±1.3mm; standard temperature accuracy of ±1°C; repeatability of ±0.6°C; and improved temperature accuracy with factory calibration.

The FLT93 Series FlexSwitch is available in two standard sensing element configurations to meet the most demanding application requirements. The FLT93S switch is designed for use in standard heavy industrial applications and in applications with high velocity liquid setpoint requirements while the FLT93F is designed for fast response gas applications. Both sensing elements can be supplied in either standard -40°C to 177°C or medium -73°C to 260°C temperature configurations. The FLT93S is also available in a high temperature -73°C to 454°C configuration.

The FLT93 Series FlexSwitch can also be supplied with a wide selection of standard and custom process connections. The electronic control circuit can be integrally-mounted with the sensing element, or it can be located in a remote location. Featuring a coated aluminium alloy enclosure as standard, the switch can also be used in ATEX locations and is rated for NEMA Type 4X (IP66) environments.
