Central
Controller (PLC)
Functions:
Normal Operation: Times opening & closing
of solenoid proportional to pipeline flow, compensated
for tank temperature.
Fail-Safe: Backup mode on loss of power or meter
signal. Output pulses programmed to user needs.
No-Flow Shutdown: May be programmed to shut odorizer
down if the station has no flow (prevents over odorization)
Control Solenoid Operation: An integral flow
detector is used to determine if the solenoid performed
properly.
Master Shutdown: If the control solenoid fails
the PLC is programmed to place the master solenoid into
emergency operation (PLC selectable),
Touch Screen Programming:
Easy to read visuals provide you with the ability to
program, troubleshoot and monitor all aspects of the
system.
Power Required:
12/24 volts DC source:
a) Uninterruptible power supply powered by 60
Hz, 115 Volts AC, using dry storage battery back-up.
b) Solar panel with dry storage battery and charging
regulator.
Gas Flow Input:
User configurable for:
a) Analog 1 - 5 V or 4 - 20 maDC proportional
to flow rate, or
b) Dry-contact pulses, user configures number
of input pulses per output pulse to solenoid, or
c) Dry-contact, one output pulse per input pulse.

Temperature
Input:
a) 3-wire, 1000 ohm platinum resistance
temperature detector, or
b) 4-20 maDC from Accu/Level transmitter,
c) manual input
Pipeline No-Flow Input:
PLC can accept dry contact or analog signal from an
external device to shut the odorizer down in the event
the station is turned off. This prevents over odorization.
Outputs:
12/24 vDC to solenoids

Pipeline Flow Instrument
Any existing instrument can be used, Flow instruments
may be supplied by user or by OdorEyes as an integral
part of the system configuration.
Odorant Tank
May be furnished by OdorEyes as an integral part assembly,
or may be adapted to users existing or new Tank.
OdorEyes tanks are made to ASME code and are code
stamped for pressure rating. Tanks typically are mounted
vertically, on three legs and are equipped with the
standard reflex sight level gauges, valves and thermowells
for RTD.
Optional Accu/Level transmitter may be included. Tanks
may include optional steel skids and containment pans.
Other Standard Components
Solenoid Valves: Explosion-proof
Bypass Regulator: Specifically selected to
suit the inlet and the outlet pressures required.
Tubing: 0.25 inch O.D. stainless steel, compression
fittings, Solenoid Valve Operation Detector
Optional Components
Odorant tanks: any size available
Electronic level gauge
Solar power
Gas flow meters
