The ARGES Level Sensor by Keynes Controls is a single-channel instrument that can detect and report water levels in the range of 0 - 50 m. The ARGES Level Sensor has been designed to be used as a stand-alone, or as part of a multiparameter device inside a Keynes Controls SONDE, and can be connected directly into a plant-wide SCADA system using the MODBUS protocol.

All of the Keynes Controls ARGES range of sensors supply measurements directly in engineering units. The stainless steel construction enables the sensors to be deployed long-term for remote applications.

Additional measurement ranges upon request. The sensor is fully integrated into the Keynes QLOG Applications software.

The level sensor can be used to confirm that the water depth into which a fluorometer has been deployed is suitable for measurements.

Measurement Integrity

All of the ARGEs sensor range have the serial numbers and the last calibration date stored internally. The user can access this information for reporting purposes. The sensors can be redeployed at any time with the calibration and serial number records are retained in the sensor.

Further Information

The ARGES level sensors offers a range of user defined setup factors such as local gravity, salinity, temperature compensation factors.

The sensor configuration can be adjusted for use in fresh and salt water.

Applications Software

The ARGES Level Sensor by Keynes Controls is supplied with a copy of the Keynes Controls Q-LOG application software.

Our Q-LOG software runs on the widely recognised Windows Operating system. You have the ability to calibrate, adjust instrument network address, and effortlessly display measurements on a series of panel meters and charts. The charts support dual Y axis parameters enabling measurements to be compared between sensors in real-terms.

The Q-LOG software can be used directly with the optional USB interface to give the User real-time measurements directly on a laptop.

Calibration Period

All of the sensors are factory-calibrated before shipment. The advanced design of the sensors means that the time between re-calibration of an instrument is minimised. Keynes Controls recommends a check calibration every 2 years. The user can adjust the calibration for a specified range to improve accuracy for dedicated tasks. A range of calibration solutions manufactured by Keynes Controls are available from the online shop.

There are two standard units for reporting turbidity - Formazin Nephelometric Units (FNU) and Nephelometric Turbidity Units (NTU). The ARGES Turbidity Sensor by Keynes Controls is set to use NTU by default.

Improved Results

The ARGES Turbidity Sensor by Keynes Controls is an intelligent sensor and stores calibration factors internally. The sensor can be re-calibrated over a smaller restricted range if the samples are under investigation are know to be of a limited range.

Optional Accessories

Keynes Controls manufactures a range of accessories that can be used with the ARGES range of chemical sensors.

A range of USB-media converters can be used to connect individual as well as multi-parameter housings to a Windows operating system computer. Free Applications Software is available for sensor configuration and making measurements.

The ARGES Brush mechanism can be individually controlled to make multiple cleaning operations for the fluorometer optics. 

Additionally, the sensors can be secured into the SONDE housing and locked into place. A locking nut secures the sensor to the housing base unit. A protective shade cap screws into the base of the unit and is used to prevent stray light for affecting the optical measurements. The shade cap also protects the sensing elements from damage. Eyelets can be screwed into the top of the SONDE housing to enable securing cables to be used to lower and secure the instruments into place.

Sensor Deployment

The ARGES Level Sensor by Keynes Controls can be installed into any of the SONDE ports and used in collaboration with any of the other supported sensors. A network connection is made using the waterproof connector. This is the same connector that is used in the SONDE as is used on the individual sensors themselves.

Once the sensor is enclosed in the SONDE housing unit, the sensor is ready for effortless deployment into the water, providing precise measurements to the connected devices.

For long term applications where any of the ARGES fluorometer sensors are being used within water then a submersible brush unit should be used to clean the sensor optics before a measurement is taken.  Any contamination of the optics due to debris in the water source can affect the results.

WARNING:

Favourable measurements made by this equipment do not guarantee that a water sample is safe for human or animal consumption. The ARGES Intelligent Submersible Fluorometer sensors can not detect the presence of harmful bacteria or toxins. If in doubt, ALWAYS TREAT SUSPECT WATER PRIOR TO CONSUMPTION.
