DEEP-TANK LEVEL BY HYDROSTATIC PRESSURE
Submersible hydrostatic level sensor for deep tanks. Calibrated on site, 1" BSPT thread, compatible with diesel, petrol, kerosene and water. TLL250 gives 0-5V output, TLL251 gives 4-20mA. Not suitable for fuels containing toluene.
Hydrostatic reading for tall tanks
A submersible hydrostatic sensor reads level by the head of liquid above it, so it handles deep and tall tanks that a fixed rod probe cannot. Choose up to 4m or up to 10m.
One family, two outputs
TLL250 gives a 0-5V output and TLL251 gives 4-20mA, both compatible with diesel, petrol, kerosene and water. Calibrate on site to suit your tank. Note it is not suitable for fuels containing toluene.
