Z9000 Optical Odorization System
protected under patent
number US 7,056,360 and others pending
The Z9000 is a feature rich, complete odorization
package that avoids the normal complexity associated
with other odorizers or the odorization process. Every action is intuitive and
predictable. The Z9000s have been working reliably in
some of the most sensitive areas imaginable (major
cities in blizzard conditions). Because of the
communication features, remote locations are also
accommodated. With only two moving parts exposed to
odorant, virtually everything can be taken care of remotely.
Literature
Principles of Operation
- An odorant storage vessel is pressurized to a
pressure above pipeline pressure. An upstream regulator
or nitrogen source is commonly used.
- Odorant moves from the vessel probe through the
filter to the isolation valve.
- When the controller opens the isolation valve,
odorant flows to the metering valve.
- As the controller opens the metering valve,
drops fall past the optical sensors into the gas
stream.
- As they fall past the optical sensors,
information is communicated to the controller. Every
drop is accounted for in our odorizer unit.
- The system controller interfaces with the
metering valve servo, optical system, gas flow
information, local interface, remote interface, etc.
to maintain a constant odorant injection
proportional to the gas flow rate.

The metering assembly is shown
below:
The encapsulated servo motor turns a precision metering
valve. Drops fall and are optically accounted for.
The controller maintains the desired injection rate by
reading the gas flow rate, odorant flow rate and
controlling the servo. If for any reason the unit is
unable to maintain injection rate, an alarm is generated
and action taken.
A local interface and a stainless steel enclosure makes the Z9000 a standalone unit.
Standard remote communications are handled through
available RS232 or Ethernet ports. Modbus and/or BSAP is
available. Free browser based software is available
through Bristol
and Zeck Systems.
