Capable of measuring a range of water characteristics, the control unit connects up to 2 sensors as standard but is expandable up to 16 sensors


The ORAKEL System is ideal for all your water monitoring equipment needs, measuring both water flow and water quality at the same time. Created as a modular system,  a wide range of water quality sensors can be added to measure various characteristics, such as pH, COD and suspended solids, for a truly bespoke and cost-effective solution.

Two sensors can be connected as standard to one controller. However, one configured system could have up to 16 sensors connected and controlled by one controller. The ORKAEL system’s range of water monitoring equipment includes three flow meters and five different pH meters.  It has a range of conductivity and TDS meters for different applications and many other sensors. All the sensors are compatible and both flow meter and water quality sensors can be configured onto one system.

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.

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.


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.
