Series 40TL

Tank Level Sensor
The Red Valve Tank Level Sensor is not affected by foaming,
ice and other conditions that can cause errors in ultrasonic and
capacitance level sensors. The Red Valve Tank Level Sensor
uses a high sensitivity, solid state pressure transmitter that is
completely isolated from the process fluid by an elastomer sleeve
that transmits pressure through a fluid fill.

t Accurate, dependable level readings ± 2”
t Can be flushed or rodded clean without
t removing from tank or disassembly
t Full 360º pressure reading
t Integral LED display available
t Simple design

The pressure transmitter is available to sense gauge pressure
for vented tanks and differential pressure for pressurized tanks.
It can easily be calibrated for process fluid density or specific
gravity in any height of tank. The output signal is 4-20 mA. An
integral LED display is available and can be calibrated in virtually any units, e.g. percentages, inches H20, etc.

t Available for both vented and pressurized tanks
t 4-20 mA output

The elastomer diaphragm provides maximum surface area with
minimum diameter allowing installation close to the bottom of
the tank. The sensor can be “rodded” from the outside of the tank
to the inside of the tank in the event of a severe blockage.
