The FTL31 and FTL33 liquid level sensors use vibrating tuning fork technology to work where float switches or conductive, capacitance and optical sensors will not.
Liquiphant FTL31 and FTL33 liquid level sensors use vibrating tuning fork technology to work where float switches or conductive, capacitance and optical sensors will not due to conductivity, build-up, foam, turbulence, flow conditions or air bubbles. They can be installed in any vertical or horizontal position in a vessel, pipe or tank. Both have an external function test feature and an LED indicator for on-site testing.
