M-Node Smart Sensors can be connected to any data gathering system, generating reliable and accurate data and communicating on a common RS485 sensor bus using Modbus protocol. Modular in nature, they allow users to assemble a monitoring package that fits individual site requirements, even in the most remote locations.

Dissolved Oxygen Monitoring applications requiring a simple 2-wire transmitter or battery-operated instrument are easily satisfied using ATI’s model Q45D transmitter.  Adaptable to either Optical or Galvanic D.O. sensors, this unit is ideal for installations where only analog signals are needed and low power operation is preferred.  For applications requiring AC operation, relay outputs, automatic sensor cleaning, or digital communication, refer to ATI’s model Q46D brochure.

Continuous water quality monitoring of ammonia is becoming increasingly important for plant operations and process control. Unfortunately, on-line ammonia monitors are generally very expensive, complex, and labor intensive instruments. Most are automated versions of ammonia selective ion electrodes methods better suited to laboratory measurements. Others are automated colorimetric devices or instrumental methods that are difficult to justify on a cost basis.

ATI`s Chlorine Monitor is an upgraded version of our proven Q45H system for continuous water quality monitoring of free or combined chlorine. Monitor capabilities have been expanded to include options for a 3rd analog output or for adding additional low power relay outputs. Digital communication options for Profibus DP, Modbus RTU or Ethernet IP have been added, as well.

Chlorine Dioxide is a powerful oxidizing agent used for disinfection of potable water, cooling towers, and food wash water. It is also widely used for the bleaching of pulp in paper mills. As a disinfectant, ClO₂ has advantages over chlorine in that it does not react with ammonia and many organic compounds while proving more effective at controlling bacteria, spores, viruses, and cysts. It is particularly well suited for removing biofilms from the inside of piping systems.

Low-level conductivity measurements are essential for a variety of water quality monitoring. The proper operation of deionizers, reverse osmosis membranes, ion exchange systems, and heat exchangers require constant monitoring to ensure high quality production. ATI’s Model Q46C2 Conductivity Monitor provides the reliable and accurate low-level water quality measurements required for such high purity water systems. Monitors provide large, easy-to-read LCD displays with a second display line for indication of temperature or other operational information. And for those applications where results in resistivity units are preferred, Q46C2 monitors can be programmed to display readings in Meg-ohm units instead of microSiemens.

While simple 2-electrode sensors are inexpensive and can provide accurate data, continuous monitoring of even relatively clean water can foul the electrodes and degrade the measurement. Maintaining accuracy is made more difficult when the amount of solids dissolved in the process varies over a wide concentration range. In this case, a simple 2-electrode sensor is limited by its cell constant, which means it cannot measure the process accurately.

Low-level conductivity measurements are essential for monitoring a variety of high purity water systems. The proper operation of deionizers, reverse osmosis membranes, ion exchange systems, and heat exchangers require constant monitoring to ensure high quality production.

ATI’s Model Q40CT blind toroidal conductivity system is designed for online monitoring of chemically aggressive process solutions.  This blind, analog version is ideally suited for applications where reliable instrumentation is critical and economy of installation is essential.

ATI’s Model C10/77 Particle Sensor is designed to provide valuable particle data by continuously monitoring particle counts in raw water, filter influent, or filter effluent. Based on a laser light blocking principle, this sensor will provide particle count data over size ranges from 2 to 400 microns, with three 4-20 mA analog outputs and an RS-232/485 digital output supplied as standard. The scaling of the three 4-20 mA outputs is selectable by use of DIP switches mounted on the counter circuit board, and can be set from 0-127 up to 0-32,000 counts per ml., with one channel proportional to total particles, one channel proportional to particles in the range of 3-5 microns, and one channel proportional to particles in the range of 7-10 microns. The digital output provides actual particle counts for particle sizes 2, 3, 5, 7, 10, 15, 20, and 200 microns. This data can be used for computerized calculations of filter removal efficiencies as well as trending of particle data.
