1.3.3 Optional Components
P2000
The P2000 is an accessory that enables secondary overfill prevention when
used with industry standard optic loading rack controllers.
MIC 10
The MIC 10 is an interface device for connecting multiple TD80s to a third
party modem.
Finch Relay Module
The Finch Relay Module is an accessory that enables overfill prevention by
control of an onboard pump or loading valve.
Horns and Lights
Alarm reporting is through optional vehicle mounted horns and lights.
1.3.4 Theory of Operation
Overview
The TD80 system consists of a TD80 transmitter, dual rod or coaxial probe
and an internal or external Finch Display. Optional components such as
horns and lights are installed as required.
The TD80 continuously measures liquid level in the tank and transmits
volume information with alarm states to the Finch Display. This information is
presented on a large 4 digit display and to alarm controlled relays. Alarms
and errors control three separate relays to signal or control external devices.
These relays indicate Spill, High-High (HH) and system Fail alarms to
external devices such as overfill prevention valves, lights, horns and
stationary loading controls.
The HH, Spill and system Fail alarms provide information to the P2000 or
Finch Relay Module and only permits loading while all conditions are safe.
HH is normally the first shutdown level; Spill is a backup level slightly higher
than HH, while Fail indicates failure of the TD80 system. Activation of any
alarm halts loading to prevent a dangerous overfill condition or spill at the
loading rack.
TD80 Transmitter and Probe
The TD80 transmits a continuous stream of radio frequency pulses into the
probe. These pulses travel along the probe and part of the pulse energy is
reflected back to the transmitter when encountering the surface of the liquid
in a tank.
Time delay between the transmit pulse and reflected pulse is used to
calculate the distance from the tank top mounted transmitter to the liquid
level.
