9900 Smart Meter
The 9900 Smart Meter provides a single channel interface for many different parameters including Flow, pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature, Level and other sensors that output a 4 to 20 mA signal. The extra large (3.90″ x 3.90″) auto-sensing backlit display features “at-a-glance” visibility that can be viewed at 4-5 times the distance over traditional transmitters. The highly illuminated display and large characters reduce the risk of misreading or misinterpreting the displayed values. The display shows separate lines for units, main and secondary measurements as well as a “dial-type” digital bar graph.
The 9900 is offered in both panel or field mount versions. Both configurations can run on 12 to 32 VDC power (24 VDC nominal). The 9900 can also be loop powered with compatible sensors.
Designed for complete flexibility, plug-in modules allow the unit to easily adapt to meet changing customer needs. Optional modules include Relay, Direct Conductivity/Resistivity, H COMM and a PC COMM configuration tool. The unit can be used with default values for quick and easy programming or can be customized with labeling, adjustable minimum, and maximum dial settings, and unit and decimal measurement choices.
9900 Transmitter Applications:
- Wastewater treatment
- Reverse osmosis
- Deionization (ultra pure water, two bed system, mixed bed system)
- Chemical manufacturing / addition
- Metal and plastic finishing
- Fume scrubber
- Cooling towers
- Media filtration
pH Water Sensor
The pH and ORP Electrodes features a patented reference electrode design and uses the unique foul-proof patented DryLoc® connector. The large area PE reference junction and pathway is constructed to increase the total reference effectiveness and ensures long service life.
The DryLoc® connector with corrosion-resistant gold-plated contacts readily connects the sensor to the mating 2760 preamplifier or the 2750 sensor electronics. The robust Ryton® threaded sensor body and choice of flat pH, bulb pH, or flat ORP sensing elements provides a broad range of chemical compatibility for a wide variety of applications.
pH Water Sensor Applications:
- Water and Wastewater Treatment
- Neutralization Systems
- Scrubber Control
- Effluent Monitoring
- Sanitization Systems
- Pool and Spa Control
- Aquatic Animal Life Support Systems
- Process Control
- Cooling Towers
