Wireless Monitoring Applications: Level Monitoring
FEDD can employ any number of methods utilizing our unique devices to monitor tank/vessel level
data and transmit it wirelessly across the facility, and beyond. FEDD offers the total wireless
solution for capturing, transmitting and integrating level data economically, across the plant,
across the road, or across the continent. The performance, reliability, integrity and service
life of FEDD devices in the some of the most rigorous and congested environments has been proven
to be unequaled.
Level Monitoring Devices
Where loop powered level monitoring instruments are in use and the output data is required at
remote locations, the use of FEDD single point wireless transmitters brings the signal to the
control room or wherever desired, without costly hard-wiring. FEDD can integrate data from other
level monitoring devices outputting analog (4/20 mA) or digital signals and transmit wirelessly
using our single point transmitters powered by battery or the existing loop. These devices have a
range of ¾ mile which can be increased to 7 miles plus using FEDD intelligent repeaters. For off-site
transmission of critical data, such as for inventory management, the use of other methods can be
incorporated into the data integration system.
Multiple Level Monitoring Devices – By Others
In the instance where data from single or multiple devices monitoring level is required at remote locations,
the use of FEDD Remote Transmitting Units (RTUs) receiving either analog (4/20 mA), digital signals or other types of protocols (such as Modbus) from the
devices and transmitting wirelessly to the control room and/or other remote locations is the optimal solution,
economically and operationally. Where loop power is not available, FEDD RTUs, solar powered with battery backup,
can provide continuous power to any instrument designed to be loop powered.
The RTU can also be equipped with an independent high and/or low-level alarm for reading a set of dry contacts.
Utilizing FEDD RTUs, system expandability is virtually unlimited. FEDD RTUs are unique in the industry, allow for
virtually unlimited flexibility in the system, are unequalled in performance and reliability and are among the most
important technical advances in wireless data acquisition, transmission and integration to date.
