Versatile ECD LQ800 Multi-Channel Controller Offers Total Solution to Disinfection and Water Quality

Anaheim, CA—May 23, 2019—Plant engineers responsible for municipal or industrial water and wastewater treatment operations will find the LQ800 Multi-Channel Controller from Electro-Chemical Devices offers them a complete process measurement analytical platform suitable for water disinfection or wastewater treatment, as well as industrial plant applications that address a wide range of parameters affecting water quality.

The highly intelligent LQ800 Multi-Channel Controller is designed to operate with up to eight digital analytical and process sensors. The measurement parameters available include well over 50 unique separate liquid measurement sensors designed to support the most rigorous municipal and industrial water treatment requirements.

For example, a typical municipal water disinfection system designed with the LQ800 Multi-Channel Controller could include ECD’s S80 Series Intelligent Sensors to monitor pH, ORP, Ammonium, Dissolved Oxygen, Nitrate, Total Suspended Solids (TSS)/Turbidity, Free Chlorine or Total Chlorine.  ECD’s input level and/or flow sensors can be added as well.

Additional S80 Sensors compatible with the LQ800 Multi-Channel Controller monitor conductivity, resistivity and dissolved oxygen (DO). Selective ion sensors are available to measure: ammonium, bromide, cadmium, calcium, chloride, copper, cyanide, fluoride, lead, nitrate, nitrite, potassium, silver, sodium and sulfide.

The LQ800 Multi-Channel Controller digitally communicates with any ECD intelligent sensor, automatically configuring the controller’s menus and display screens to the measured parameter.  Two-way communication between the sensors and controller provide measurement data for plant process control equipment and systems

The type of sensor, identity and serial number are stored in the sensor’s memory along with calibration registers. Sensors are calibrated at the factory–so they are ready to use when connected, are waterproof and submersible with all internal components epoxy encapsulated inside the housing and have various process fittings and configurations.

The LQ800 Multi-Channel Controller features a large easily viewable color touchscreen display, which is sized at 4.6 (w) -x- 3.5 (h) inches (120 -x- 90 millimeters). The display and interface can be web-enabled with remote monitoring and activation with personal handheld devices and computers with access via the internet.

The LQ800 Multi-Channel Controller’s highly intuitive menu-driven navigation is accomplished using the large touchscreen display. The primary menu selections are the multi-channel main display, single channel detail screen, calibration menu, configuration menu, info screens and simulate menu.

Other display screen capabilities include the hold function, graphical display style, back light and contrast adjustments, labels/tags for naming the transmitter, password protection and a factory default reset. Output screens include setting the digital communications output, setting the 4-20 mA ranges and fault settings, and configuring the alarm relays.

While ECD’s S80 Intelligent Sensors come pre-calibrated from the factory, field calibration adjustments are easily performed with the controller. The LQ800 Multi-Channel Controller’s calibration menu includes an auto calibrate function, a two point calibration, a standardize function and a single point calibration. The controller’s manual calibration function allows previously determined offset and slope values to be entered manually.

For large or complex processes, the LQ800 Multi-Channel Controller can be ganged with multiple units or connected to other ECD on-line analyzers.  Available output options include: eight 4-20 mA outputs, eight configurable relays (for alarm, activated timers, control, and fault), and Ethernet communication.  Data logging capability is available as well

The rugged LQ800 Multi-Channel Controller is available as a 24 VDC or 100/240 VAC powered controller. It is constructed with heavy duty materials suitable for rugged environment requirements and carries a NEMA 4X/IP65 rating for water resistance.  It is suitable for use in temperatures from 15 to130°F (-10 to 55°C).

The compact LQ800 Multi-Channel Controller goes almost anywhere and measures only 17i (W) -x- 11.7 (h) -x- 9 (d) inches (43 (w) -x- 30 (h) -x- 23 (d) centimeters).  It weighs just 20 pounds (9 kilograms), is wall mounted (standard) with optional handrail or stand mounting available and an optional sunshield is available too for high-intensity light locations.
