A natural
component of any successful telemetry installation
is the outstation. Also referred to as the Remote Terminal Unit (RTU), this
data collection device operates for 24 hours each day, gathering from a
particular remote site’s sensors all of the information that is then relayed
back to the main office. Amongst the Oriel Systems (http://www.orielsystems.com) product
range are video and low power outstations for various purposes, as well as its
Intelligent Telemetry Outstation (ITO).
It is this
latter product that can be attached to various different types of IO module, or
even PLCs and other intelligent devices, as part of its programmed monitoring
and control of a remote site’s plant equipment. This arrangement allows for the
full configuration of the telemetry
system for a particular site, with the option also being there for further
functionality enabling the connection of the unit to the client’s own
specialist hardware. Various communication transmission options exist so that
the unit and master station can be connected, with a live feed being reported
of site events and previously recorded values sent back as required.
Amongst the
possible communication options are, for unlicensed frequencies, GSM / GPRS /
3G, Low Power Radio Outstation 10mW – 750mW complying with MPT1329, (now
replaced by the ETSI Standard EN 300 220), while Low Power Radio Outstation
100mW – 5Watt complying with MPT 1411, (now replaced by the ETSI Standard EN
300 220, EN 300 113, MPT1411) exists for licensed frequencies. Serial protocols
RS232 / RS485 are also possible, besides standard telephone provider landline,
broadband or PSTN.
It is possible
to connect Oriel Systems’ ITOs to either digital or analogue signal outputs
from the likes of Ultrasonic level sensors and Guided Microwave sensing
equipment, while these telemetry
systems can also have counter frequency outputs brought into them, such as
from pumps for the purpose of measuring product consumption or movement.
Functions such as the remote opening and closing of valves can be controlled
via control outputs, while the system can also alert the operator, in such a
form as a text or email, in the event of any remote site parameters being
exceeded.
The ITOs of
Oriel Systems are proven for a wide range of applications, from flood
alleviation schemes and land drainage to flood defence and borehole water
extraction, in the water industry alone. Meanwhile, the printing, fuel, gas,
chemical storage and similar industries have continually turned to these telemetry solutions as a means
of remotely monitoring/gauging the chemicals, fuels, ink or other products
carried by tanks or silos.
The supplier
can, with the assistance of Remote Inventory Management and Vendor Managed
Inventory solutions, remotely monitor customers’ product stock levels and
therefore save costs on the transport needed to top them up, as part of a “Just
in Time” delivery philosophy. Contact Oriel Systems (http://www.orielsystems.com) now about
putting in place an effective tank or silo
monitoring system.
