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.
