Reverse Osmosis Monitor

The Model 2450 Reverse Osmosis Monitor uses LONWORKS* Technology that is the latest in microprocessor capability, giving the user the highest level of application flexibility. A large illuminated graphics screen, multiple inputs and very easy setup with easy field upgrades characterize this new technology. Water meters and sensors are purchased separately.


  • Uses 2-electrode or 4-electrode conductivity sensors.
  • Uses differential pH sensor with inch MNPT process connection. pH input can also be configurable for an ORP sensor.
  • Two water meter inputs for Permeate and Concentrate flow rates.
  • RS232 output for remote monitoring, control and data acquisition (-RS2L).
  • Includes -RTC card
  • 4-20 mA output for (-35L, select any four, two per -35L card):
    - pH, conductivity, temperature,
    - concentrate flow, permeate flow,
    - percent recovery.
  • Input for CIP lockout.
  • System run timer.
  • Five (5) Count down timers
    - Lubrication interval
    - Check CIP
    - Check Filters
    - Check Membranes
    - Check Sensor
  • Four (4) relays have user-selectable options:
    - pH setpoint;
    - conductivity setpoint;
    - temperature setpoint
    - permeate flow setpoint;
    - concentrate flow setpoint;
    - percent recovery setpoint;
    - various alarms.

2450 LONWORKS Technology-based Reverse Osmosis Monitor including the Real Time Clock (-RTC) option. Sensors and water meters are ordered separately.

CONTROLLER OPTIONS (optional; select no more than two)
- 35L Two 4-20 mA outputs.
- 35L2 Two additional 4-20mA outputs. This option is used in conjunction with the -35L card for a total of four 4-20 mA outputs.
- RS2L Communications node with the LRWS program.
