Model AS-MLLS Multipoint Liquid Level Switch
Brand: Fluid Components International LLC (FCI)The Fluid Components AS-MMLS is a liquid level element with solid state multipoint electronics.
FCI provides multipoint liquid level and interface switches that include a “strip sensor” or a thermowell mounted sensing element with integral or remote electronics that provide indication of presence or absence of liquid or interface at the multiple sensor locations along the length of the element.
The multipoint liquid level element is directly installed into tanks, reservoirs, sumps and gearboxes on commercial and military aircraft, spacecraft, vehicles and marine applications. Optional temperature output and controller function is available.
