Flow and temperature measured by one
switch
Flow and level switches monitor, control and alarm flow rates or levels of critical fluids such as water, air, gases, coolants and lubricants in metals and material processing and equipment.
Process, plant and manufacturing engineers and equipment designers involved in raw metals, fabricated metals or advanced materials production will find applications for the Flexswitch FLT series flow and level switches from Fluid Components They provide monitoring, controlling and alarms on flow rates or levels of critical fluids such as water, air, gases, coolants and lubricants used in metals and material processing and equipment
Its rugged, industrial design and housing provide reliability and long service life in harsh plant environments.
The FLT switch is a dual-function instrument that provides flow and temperature, or level and temperature sensing in one device.
Available in insertion and in-line styles for either pipe or tube installation, a single FLT measures and monitors flow or level and temperature simultaneously with accuracy and reliability.
Dual 6A relay outputs are standard and are assignable to flow, level or temperature.
It suits applications such as coolants where low flow or high temperature alarms are needed to warn operators of equipment cooling system failure.
Typical applications include equipment involved in metals forming or fabricating, cooling, curing, moulding, stamping and cutting.
The switch is suitable for use with water and other coolants, fluids and gases in the metals and advanced materials industries.
It suits arc and robotic welding systems, laser or plasma cutting equipment, plating systems, punches and presses.
The switch operates over a flow range in water from 0.003 to 0.9m/s, making it suitable for water cooling and equipment lubricant applications.
Switch point accuracy of 2% and measuring repeatability of 0.5% of reading ensures accurate, reliable operation.
The standard configuration FLT withstands operating temperatures up to 177C, and optional versions are available up to 454C.
With its thermal dispersion mass flow sensor, the switch has built-in temperature compensation which ensures repeatable and reliable operation, even in extreme environments, such as those found in the high temperature steel, metalworking and advanced materials industries.
This automatic compensation adjusts the instrument for changes in operating environment temperatures to ensure the trip points will remain accurate in metals and materials plant applications, and will prevent false alarms or alarm failures, improves end-product quality, increases operator safety and allows alarms to be set within a narrower set point range.
The thermal dispersion sensing technology provides accurate, highly reliable and dependably repeatable indications of flow rate, liquid level/interface and temperature operation.
With the switch, there are no orifices, traps, pivots, paddles, gears, bearings or other mechanical elements to foul or fail, making it reliable and dependable in dirty environments, such as metal working plants.
A sanitary configuration is available for advanced materials produced in clean plant environments.
Standard and custom process connections can be provided.
The electronic control circuit can be integrally mounted with the sensing element, or it can be located in a remote location.
The standard enclosure is made from a coated aluminium alloy.
It is suitable for use in Atex locations and is rated for Nema type 4X (IP66) environments.
Stainless steel or fibreglass enclosures are available.
