FT Down Hole Submersible Liquid Level Transmitter
Continuous Analog Sensor

                                                                                                   

The FT Transmitter indicates the level of liquid by continuously measuring hydrostatic pressure via its isolated sensing element.   The data is transmitted by a 4-20 mA output signal.  This design provides for excellent linearity and repeatability, low hysteresis and long term stability.  The FT sensor is easy to install; simply lower the transducer into a vessel or well.  It's that easy.  All the electronics are mounted in a submersible 316 stainless steel housing.  Standard with Polyurethane cable and Viton Seal.

 

A special cable support bracket is also available.  This gives extra stability to the transducer when used with longer lengths of cable (up to 2500 feet) or when used in an agitated liquid.  A conduit adapter is also available.

 

The FT is also available calibrated for any span needed, from 0-6 psi ( 0.4 bar, 14 ft or 4.2m of water) to 0 to 300 psi (20 bar, 0-690 ft or 0-211 meters of water).  Other optional outputs include 0.5 to 4.5 Vdc, 1 to 5 Vdc, 1 to 6 Vdc, or 0 to 5 Vdc.
