Data acquisition is an important function in Continuous Emission Monitoring Systems (CEMS). The main objective of the data acquisition system is to provide real time reports that can be used for compliance reporting, process improvements and environment performance management. With in-built GSM/LAN connectivity, the gas readings are uploaded to the cloud, where they can be viewed from anywhere in the world on a laptop or mobile device and alarm functions can easily be configured, allowing 24/7 continuous monitoring.
Sample Extraction and Conditioning System or Membrane based Sample Conditioning System
“Membrane based sample conditioning system is for dry sample extraction. This is needed where highly soluble and corrosive acidic gases are present in the sample to be extracted. It reduces the dust load and moisture content in the sample to transport it to CEMS without a heated sampling line. This reduces the running cost of the overall system. The system is specially designed for extracting highly corrosive gases like HBr, F2, HF, HCl and Cl2 from the stack. The system can be directly mounted on the stack with the flange connections and is used where the stack temperatures are <100°C and where very low dewpoints are necessary. The power required to run the system and the necessary communication is established from the CEMS through a cable running between them. “
The Uniphos Simple Sampling probe is tailor made for situations where temperature of the stack is not high, and condensation does not happen while extracting the sample from the stack. The dust filter present in the probe ensures that no dust is passed through the line. User-Settable purging facility enables automatic purging of the probe at pre-defined time intervals.
The Uniphos TSS probe utilizes optical spectroscopic technique to determine the presence of suspended solids in Industrial wastewater, surface water, etc. Utilizing an IR light source and IR detector to determine the TSS, as well as a solenoid valve for auto purging/ cleaning the sensor, the instrument provides an accurate and affordable solution for TSS monitoring in wastewater.
Equipped with a next generation touchscreen HMI controller for display and programming the unit, the probe provides a variety of data communication options such as RS-485 MODBUS and industry standard 4-20 mA analog output.
The emission of pollutants such as CO, CO2, NO, NO2, total NOx, SO2 etc. from stacks are often measured and reported for regulatory compliance purposes on a mass flow rate basis. Mass flow rates are typically calculated and reported in units of lbs or kg per hour and tons per year for these pollutants. The pollutant mass flow rate is a function of the pollutant concentration of the stack gas, the stack size & shape, and the stack gas velocity.
The Uniphos Integrated Temperature, Pressure and Flow Probe is meant for continuous and real time measurement of Temperature, Pressure and velocity of gases in industrial stacks. All the three sensors are integrated on a single flange and can easily be mounted on the stack without any hassle.
The Uniphos Envirotrack is microprocessor based portable instrument custom made to measure the pollutants in the Ambient Air. It comes with an Air sampler where the sample air is scrubbed in a solution specific to the pollutant. The pollutant gas dissolves in the gas specific chemical and is further processed to produce a colored dye. The instrument measures the absorbance of light passed through this colored dye and relates it to the concentration of pollutants in ppb levels.
With datalogging included as standard and the presence of a USB interface, the user can easily transfer the stored data along with time and date to a computer.
FumiSense Pro–Hi is a handheld gas monitor for phosphine concentration measurement when CO is present along with phosphine, like in tobacco fumigation. Equipped with an inbuilt air sampling pump capable of drawing a sample from a distance of 30m and a sensor capable of measuring PH3 up to 2000 ppm, it is the perfect tool for this application. The backlit OLED display enables the user to read the instrument display even in the dark. With user settable datalogging features, the device logs gas concentration values with date, time and location.
FumiSense Pro-Lo is a handheld Methyl Bromide monitor for monitoring Methyl Bromide levels outside the fumigated stack/ silo/ ship to check for leaks. Equipped with an inbuilt air sampling pump and with the ability to measure MBr up to 200 ppm, it is the perfect tool for this application. The backlit OLED display enables the user to read the instrument display even in the dark. With user settable datalogging features, the device logs gas concentration values with date, time and location.
