Wireless Oxygen Monitoring in Fish Farming and Wastewater Treatment

Our automatic wireless oxygen buoy offers an economical and simple solution to
monitoring and controlling dissolved oxygen levels in fish ponds or wastewater ponds.
Just place it in a pond and the oxygen readings are transmitted automatically to any PC
within range(seven miles line of sight - longer with repeaters). The buoy is self-contained with a self-cleaning oxygen sensor. A battery that is kept charged by a solar panel powers it. Aerator control and running status is provided by a wireless controller that is activated by wireless commands from a host PC. Software is included for the host PC. The software also provides automatic alerting by telephone.

This is an excellent product for any size fish farming operation or wastewater pond system. It provides constant visibility concerning the oxygen status of all ponds. Its low cost makes it affordable for any aquaculture operation where oxygen monitoring is required.

The benefits of the system are many. It reduces manpower required to check oxygen manually. It reduces energy costs involved in vehicles used to check oxygen as well as energy used to run aerators since aerators are only run when necessary. It allows an operator to look out for other operations instead of being tied down to the monitoring of the ponds. For catfish farmers who also farm conventional crops this product can make
life much easier.

Self-Cleaning Oxygen Sensor

The oxygen sensor used with the oxygen monitoring buoy is kept clean of any contaminants such as algae or mineral deposits by a rotating brush that activates for a short period of time just prior to making an oxygen reading. The rotating design uses less power to activate and its geared drive provides extra force to keep the oxygen sensor clear of any build up.

Wireless Machine Monitoring in Textile Production

Modern textile machines are normally equipped with processors that monitor the
performance of the machine. These processors are equipped with some type of communications port to allow the transfer of collected data to a central computer for analysis of the operation of multiple machines. A frequently used method for collecting the data is a wired daisy-chained system using RS-422 communication protocol. The disadvantage of this system is the initial cost of the wiring and the possible signal interference along the entire chain if a communication problem develops in a machine connected to the chain. These problems are difficult to diagnose and in some cases can cause damage to the processors on other machines.

Our wireless RS-232/422 system overcomes the above disadvantages. By installing a wireless modem on each machine each machine can communicate with a host computer equipped with a wireless modem without any wiring costs. In addition, each machine communicates independently from the others so problem diagnoses are easy and there is no possibility of damage from the failure of another processor.

Fabric Inspection

Our fabric inspection system features the Uster Technologies Fabriscan automatic fabric inspection system coupled with our highly efficient Cut Optimization system that maximizes the output quality of any fabric production process.
