Description

Optional comms packages allow Profibus, Modbus ASCII, Modbus RTU, Modbus TCP, 4-20mA analogue outputs and relays for alarms and control.

The ORAKEL controller is equipped with a display screen, readings can be taken directly from the control unit or downloaded from the internal data logger. An optional Detectronic modem allows for remote communication capabilities.

KEY FEATURES
PID Control
Full PID control suitable for nearly all dosing requirements, from simple to very complex processes.

Diagnostics
Includes a full set of instrument and measurement diagnostics.

Precision Positioning
An integrated signal oscilloscope optimises sensor positioning and diagnostics.

Easy Configuration
Includes a comprehensive internal database of pipe, fluid and lining materials.

Built-in Parameters
Built-in fluid parameters allow calculation to compensate for sound speed, density, viscosity, specific heat capacity and temperature (if temperature is known from optional temperature probe).

Flexible Measurement
Liquid can be measured in M, m3, USgal, mg, cf, bbl and Imp bbl. All measured values can be selected as flow rate per second, minute, hour or day and are automatically totalised.

Data Analysis
An optional GSM data-logger can be added and date sent to an online portal for detailed analysis.

APPLICATIONS
The ORAKEL System is suitable for use in closed, partially filled and open channels.

The wide variety of sensors that can be added make it suitable for many applications, including:

 Municipal and industrial wastewater

 Chemical process

 Food and dairy

 Paper and pulp

 Pharmaceutical

 Brewing

 Other process industries.
