Micro ISCM Streaming Current Monitor

nnnn

The M icro I SCM establishes a new level of control for plant operators that depend upon Streaming

nnnn

Current to maintain water quality. Unlike other systems, the instrument can be calibrated to a known

nnnn

Ion Charge unit (ICu) value, using a cationic polymer solution. Once calibrated, the operator can use

nnnn

the M icro I SCM to determine the control set-point for the plant. This set-point is established through

nnnn

optimization and it reflects the actual ICu of the sample stream.

nnnn

Standard Features

nnnn

• Graphical Display

nnnn

Quickly view historical trending of ICu readings over an 8 or 24 hour period.

nnnn

• Calibration to a Known Value

nnnn

Maintains accuracy over the life of the probe.

nnnn

• Built-in Diagnostics

nnnn

Full time diagnostic software automatically monitors and detects errors.

nnnn

• On-Screen Instructions

nnnn

Easy to use menus guide the operator through set-up and calibration

nnnn

procedures.

nnnn

• User Programmable Offset

nnnn

Simplify human interface by setting the output to reflect zero when optimum

nnnn

dosing conditions are met.

nnnn

• Three Separate Alarm Contacts

nnnn

System alarm and two user-programmable Hi/Low ICu alarms provide

nnnn

continuous confidence in the measuring process.

nnnn

• High / Low Gain Switch

nnnn

Optional Features

nnnn

• Flow Alarm

nnnn

Automatically alerts the operator if there is a disruption in flow to the sensor.

nnnn

• Proportional Integral Controller

nnnn

Automatically controls coagulant dosing.

nnnn

• Serial Ports _

nnnn

The optional RS-232 or RS-485 serial ports allow the Micro I SCM to easily

nnnn

adapt to a digital environment.
