PRECO Pump Injection Odorizer System
Principal of Operation
The operating principle of Pump Injection odorization is to use un-odorized supply gas to operate a liquid odorant injection pump in high pressure or no pressure differential situations. This is accomplished by tapping the transmission or feeder line for supply gas and controlling the operation of a solenoid valve to drive the metering pump, which injects liquid odorant at a drip tap on the feeder or distribution line. A signal from a flow computer or a meter interface switch is received by the PRECO Controller to actuate the solenoid valve that operates the injection pump. The controls can operate on 110 VAC or 12 VDC.
The PRECO Controller is a Solid State Controller. It receives signals proportional to flow, from the customer’s gas line instruments or meter interface switch. The system operates on 110 VAC or 12 VDC with PRECO Solar Assembly.
PRECO Pump Cabinet
The PRECO PUMP Cabinet is equipped with a Morgan HD Series Pump, a pneumatically operated timer that is automatically enabled in the event of power failure. “Swagelok” brand stainless steel fittings and tubing are used throughout the unit.
PRECO Pump Unit
The PRECO Pump Unit is available with Pump Cabinet, Day Tank, and Bulk Tank all mounted on one easy to install skid or Containment Tub. Day Tanks are designed to hold approximately one months supply of odorant. Bulk tanks are designed to hold one years supply of odorant.
