Streaming Current Monitor Micro SCM From HF Scientific

Micro SCM Streaming Current Monitor
The Micro SCM Straming Current Monitor establishes a new level of control for plant operators that depend on Streaming Current to maintain water quality. Unlike other systems, the Micro SCM Straming Current Monitor can be calibrated to a known Ion Charge unit (ICu) value, using a cationic polymer solution. Once calibrated, the operator can use the Micro SCM Straming Current Monitor to determine the control set-point for the plant. This set-point is established through optimization and it reflects the actual ICu of the sample stream.

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

Calibration to a Known Value
Maintains accuracy over the life of the probe.

Built-in Diagnostics
Full time diagnostic software automatically monitors and detects errors.

User Programmable Offset
Simplify human interface by setting the the output to reflect zero when optimum dosing conditions are met.

On-Screen Instructions
Easy to use menus guide you through set-up and calibration procedures.

Three Separate Alarm Contacts
System alarm and two user-programmable Hi/Lo ICu alarms provide continuous confidence in the measuring process.

Made in the USA

Flow Alarm

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

Proportional Integral Controller
Automatically controls coagulant dosing
Serial Ports
The optional RS-232 or RS-485 serial ports allow the Micro SCM Straming Current Monitor to easily adapt into a digital environment.

Establishing an actual ICu value for the control set-point ensures the operator can always return to the same conditions in the event of a plant upset, equipment failure, or shut down. Routine calibration ensures that the integrity of the output can be maintained by compensating for standard wear-and-tear on the probe and electronics.

The graphical display of the Micro SCM Straming Current Monitor provides the operator a fast and easy way to keep up with what is going on inside the plant. Historical trending of readings over the previous 8 or 24-hour period is continuously displayed as a graph on the screen.

The sensor design incorporated into the Micro SCM Straming Current Monitor was developed by Lechintech International to operate under the turbid conditions found in the water supplies of South Africa. The HF Micro SCM Straming Current Monitor, coupled with leading-edge sensor technology provides an easy-to-use tool for precise control over your chemical dosing system.
