Our Equipment Water Quality Monitors ORAKEL
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.
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.
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:

The ORAKEL range of Residual Chlorine Analysers, Residual Chlorine Controllers and Residual Chlorine Monitors are membrane devices which are insensitive to changing pH, use no reagents, are extremely stable, and have reduced maintenance and reduced whole life costs.
The membraned amperometric chlorine sensors are enhanced with a third, reference electrode which eliminates zero drift. Its unique design means that pH correction is not usually required at all, completely eliminating reagents.
Particle counters are known for their ability to detect when a filter is reaching the end of its life. ORAKEL Particle Counters are sophisticated instruments suitable for municipal and industrial water treatment applications including filter performance monitoring, protecting RO membranes from colloidal fouling and corrosion product monitoring.
The ORAKEL Suspended Solids senor has a large dynamic range, which eliminates the need for a “zero” and also eliminates the effect of background light.
For multiple measuring ranges, the suspended solids sensor can monitor turbidity and suspended solids from 2 NTU (1mg/l) to 8%* solids.
The ORAKEL COD/TOC Sensor uses UV254 light as a surrogate measurement for detecting organics in water.
It is designed in modular form so that it can be integrated with other sensors, such as pH, turbidity and dissolved oxygen, to provide all the tools needed for either a stand-alone UV254 analyser or as part of an effluent discharge monitoring system.
The ORAKEL COD/TOC Sensor provides online continuous organics monitoring utilising a 254nm ultraviolet light source.
The pH5 electrode has a double-junction reference to prevent contamination of the reference from sample components.
This design gives the electrode a longer life compared to ordinary electrodes (up to 3 yrs). The electrode also has a hemi-shaped glass measuring surface which is more durable than the traditional bulb-shaped glass.
Sitting at the top end of the market place, the ORAKEL pH probe has a longer life and lower maintenance requirements. Typically it only needs calibrating once every two or three months, making it a very cost effective solution.
Optical luminescent devices which are extremely resistant to abrasion, extremely stable, and have greatly reduced maintenance and whole life costs.
The ORAKEL Dissolved Oxygen sensor has no chemicals or moving parts. It is stable and reliable making it excellent for process controls and is suitable for all Dissolved Ovygen applications.
