LiquitronTM Controllers
DC5500 Cooling Tower Controller with Remote Programming & Communications -
The DC5500 has all of the features of the popular DC4500 Controller(see below); dual biocides & inhibitor pumps control, 0-20,000mS conductivity range,
four feed modes, etc. The DC5500 also has the additional features of a second water meter input, three tank level inputs, and most importantly-
communications capabilities to download historical data, view real time conditions, and program the controller remotely. Each DC5500 has an RS232 serial
port for data downloads into a pc or Palm Pilot™, or for quickly programming the various controller settings with a computer in a user-friendly pull-down
menu format. Up to (31) DC5500 Controllers can be linked to a single LiquiComm Communications Module for remote communications on a standard analog
phone line. The DC5500 can be used with a LiquiComm Communications Module and the LMI DataComm Software as a complete information management
system for remote cooling tower accounts.
DC4500 Cooling Tower Controller
The DC4500 is a bleed and feed cooling tower controller with dual biocide timers. Standard features include; four feed modes (Feed & Bleed, % of Time, % of
Bleed, Flowmeter Pulse), intermittent or continuous sampling, uS or PPM display, flow totalizer, manual test modes, temperature display, biocide cycle of 7,
14, or 28 days, biocide lockout, and conductivity or time-based biocide prebleed. Programming is simple and is accomplished with only three keys. The
backlit liquid crystal display and LEDs provide a visual indication of operating conditions and equipment status.
DC4000 Cooling Tower/Boiler Controller
The DC4000 may be programmed as a bleed and feed cooling tower controller or boiler controller. Standard features include; four feed modes (Feed & Bleed,
% of Time, % of Bleed, Flowmeter Pulse), intermittent or continuous sampling, uS or PPM display, flow totalizer, and manual test modes. The boiler mode
includes a time-trap sampling method that prevents the flashing problems that are so common in boilers. Programming is simple and is accomplished with
only three keys. The backlit liquid crystal display and LEDs provide a visual indication of operating conditions and equipment status.
AC4000/5000 Cooling Tower Controller
These new analog cooling tower controllers bring state-of-the-art technology to the entry-level controller market. The AC4000 is a simple, low cost feed and
bleed controller. The AC5000 features three selectable feed options (Limit, % of Time, Flowmeter Pulse). Both controllers feature rugged, iron vane meters
and a clear, lockable cover.
DP5000 pH Controller
The DP5000 pH
Controller is designed for a variety of industrial pH applications including water treatment, metal finishing, PCB manufacturing and waste
treatment. It provides on/off or proportional (pulse) control of metering pumps for addition of acid or base. Level and flow inputs and alarm outputs are
standard. An advanced menu includes special features such as the solenoid dump valve control for batch treatment and a "Point 3" (inflection point)
adjustment for fine tuning the control profiles of the metering pumps. 4-20mA output is optional.
DR5000 ORP Controller
The DR5000 ORP
Controller is very similar to the DP5000 described above, however, it is designed to control LMI Metering Pumps for the addition of
oxidizing and reducing agents. It shares the same features and options as the DP5000 and is often used in water and wastewater treatment, fruit processing and metal finishing.
 Only
FS5000 Flow Switch Controller
The FS5000 Flow Switch Controller
is designed for use in applications that require flow/no-flow control of metering pumps and other devices. It includes a
flow switch and three (3) 115V receptacles that are powered with flow and one (1) 115V service receptacle. Power indicator light, flow indicator light and test
switch are included.
