Accu/Line Injection Systems Specifications

Central Controller (PLC)

Functions:
Normal Operation: Controller is programmed to inject odorant proportional to pipeline gas flow at a preprogrammed odorization rate in pounds/mmcf.
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) Solenoid Valves Three-way, 12/24 vdc, explosion proof,
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.
Outputs:
12/24 vDC to solenoids
Dry contact, common alarm
Electronics Enclosures

Pump Cabinet:
Dimensions in inches: 30 W x 30 H x 8 Deep (May vary according to options)
Environmental and Electrical Safety:
NEMA-3R or NEMA-4R (weather tight gasketed with stainless steel hardware) primed and epoxy coated.
Optional explosion-proof enclosure.
Operating temperature; -30 to +120 Degrees F.
Operating relative humidity: 5% to 100% condensing.
Optional heater available.
Odorant Tank:
OdorEyes tanks are made to ASME code and are code stamped for pressure rating. Tanks typically are mounted horizontically and are equipped with the standard reflex sight level gauges and valves,
Optional Accu/Level transmitter may be included. Tanks may include optional steel skids and containment pans.

Piping and controls for a typical system. Odorant flows from the tank, through a filter, gas flow meter and a liquid odorant flow meter to the gas pipeline. Signals from the gas flowmeter and the odorant flow meter are used to control the pumps (via solenoid valves) providing the odorant to the pipeline. The odorant meter alerts the PLC o1 pump failures, vapor-lock
or other problems. The PLC will respond according to it's programming. Responses can include operating the pump several times to clear the problem, switching to an optional standby pump, generating on alarm or shutting down the system.
