OdaLog Logger L2

SKU: odalog

The OdaLog Logger L2 is specifically designed for the wastewater industry, primarily for locating Hydrogen Sulphide (H2S) emissions in harsh, humid, and dirty wastewater environments. 


The OdaLog is popular with the UK's large water companies for odour control management


The OdaLog also detects H2S, CO, SO2, NO, NO2, NH3, HCN and Cl2 at various detection ranges. Please contact the sales office for these configurations

Product Description

Details

Hydrogen Sulphide (H2S) is a detectable gas in low concentrations and is a major problem in sewers. H2S attacks concrete and mortar above the liquid level in pipes and chambers causing it to corrode and deteriorate. H2S can also cause nuisance smells for neighbours of wastewater treatment plants and must be controlled.

Anywhere that currently has or potentially has an odour or corrosion problem, an odour control program should be in place to identify the severity of the problem. Such a program should involve careful evaluation of the data obtained from sample collection and analysis. Because the collection of samples or inspection can be hazardous, plant operators and sewer workers must be familiar with the potential dangers of confined spaces in contact with wastewater. A gas detector should always be used prior to entry and during the inspection.

a1-cbiss supply the OdaLog - a datalogger specifically designed for the wastewater Industry, used primarily for locating at or close to the source of H2S gas emissions such as within sewerage pumping stations and manholes. It has been designed to help drainage authorities, water companies and environmental regulators reduce the costs of monitoring and also improve timely on-line access to high quality measurements at remote sites.

Long Life Sensor

The Long life sensor has a small aperture which absorbs moisture at a slower rate compared to the standard sensor. This means that the long life sensor can be deployed for up to 4 times as long as the standard life sensor.

OdaLog LL models should be deployed no longer than 4 weeks at a time (with 2 weeks recovery time on Dry Dock or 4 weeks in ‘office’ conditions)

Where is the OdaLog used most effectively?

Odour abatement

Odour abatement management and control takes place at wastewater and sewage treatment works where they process sludge and wastewater. This is an extremely sceptic process and odours must be controlled by a combination of liquid dosing and dry scrubbing technologies.

Liquid dosing is intended to reduce the sulphide levels to an acceptable level prior to the dry scrubbing system, so that the final scrubbing leaves a gas stream in a non-noxious state.

The OdaLog can be integrated into a dosing system to log levels of Hydrogen Sulphide (H2S) allowing the dosing chemical to increase or decrease in reaction to the H2S levels. This provides a fully automated odour abatement chemical dosing system

A Unique Design

Due to the nature of the environment in which the instrument has to operate, it has been designed to be splash resistant, robust, small, and able to log data for extended periods of time making it a unique datalogging product of its kind.

Datalogging and Reporting

OdaStat-G can interface with a PC through an IrDA or internet connection. The software allows data to be presented in tabular or graphical form to highlight significant variations in H2S levels over time. OdaStat-G needs to be purchased with an OdaLog if not already previously owned

OdaTrak

OdaTrak™ 4 to 20mA adapter

The OdaTrak™ 4 to 20mA adapter reads gas concentration data sent from an OdaLog® gas logger over a fibre optic cable. This then deciphers the data, and then outputs the corresponding 4-20mA loop analogue signal. This allows the OdaLog® unit to be interfaced to control and telemetry systems providing real-time gas data.
 
This signal could be used to optimise chemical dosing, trigger alarms, control ventilation fans, or interface to telemetry systems etc.

Sensor Recovery Time

Whilst the OdaLog has been designed for use in a wet, toxic and humid environment, the OdaLog's gas sensors will require recovery time in what we call 'office' conditions (dry, air conditioned). If you require continuous datalogging, consider purchasing two OdaLogs so one can be recovering whilst the other remains in-situ. The OdaLog Dry Dock can reduce recovery time by half.

Recovery time in air conditioned office (40% to 60% RH)

Deployment Time

OdaLog SL models should be deployed no longer than 1 week at a time (with 3.5 days recovery on Dry Dock or 1 week in ‘office’ conditions)

OdaLog LL models should be deployed no longer than 4 weeks at a time (with 2 weeks recovery time on Dry Dock or 4 weeks in ‘office’ conditions)
