when installed as replacements to conventional “Green Tipped”
Thermistor sensors. FloTech Thermo-Optic sensors and electronic
dummy provide high reliability, long life, and quick start up in cold
weather. “Civacon” is a registered trademarks of Civacon / Dover
Corporation.

Installation

1. FloTech model FT151 can be mounted in a 2" NPT female pipe
coupling or through a 2 3/8" hole. When mounting in a 2 3/8" hole,
the gasket and lock nut provided are used to retain the probe holder
in the tank shell or manhole. After the sensor is mounted remove the
cap.

2. Loosen the probe clamp screw and adjust the probe to the correct
level point. This is typically 3% of compartment volume. It is not
recommended cutting the standard 7" sensor to a shorter length.
This will cause insufficient time to stop the flow of product within the
load racks reaction time.

3. The actual sensing point adjustment should be determined by the
total response time required to prevent a tank overfill condition. The
FloTech sensor reaction time is one half second. The loading rack
will also have a reaction time. Once the probe is adjusted to the
proper height, tighten the clamp screw.
