  • Sewer Meter -

    Sewer Meters monitor sewage level and flow within the sewers. Benefits gained by sewer monitoring include: (1) Detection of overflow conditions before overflow occurs thereby preventing hazardous environmental events. (2) Detection of blocked sewer pipes, allowing quick and focused maintenance thereby reducing maintenance costs. (3)Detection of over-used and under-used pipes for long term municipal planning. (4) Monitoring of sewage flow in sensitive sites such as flow to the river or sea. (5) Estimation of sewage flow for costing purposes and especially for pricing the use of public infrastructure by industrial plants. The sewer meter solution consists of two main components: (1) The fielded component includes GaugerGSM, an ultrasonic non-contact level sensor integrated with GSM cellular transmitter. The fielded component also includes accessories such as external battery pack. (2) A web-based monitoring application for presenting data from all sewer sites.

  • Remote temperature monitoring

    To abide local regulations, and ensure efficient and effective composting, the temperatures of the windrows must be measured and logged constantly. With accurate temperature measurements, you can determine the optimum time to turn the windrows for quicker compost production. Time consuming and error prone manual data collection is eliminated using a SureCross FlexPower Node equipped with three thermocouples to automatically monitor the temperature at three depths within a compost windrow. Temperature sensor readings are wirelessly transmitted back to the Gateway or host system for data collection, analysis, and logging. Because the temperatures are measured and recorded continuously, the composting rows can be turned as soon as the temperature reaches the ideal point. Continuously monitoring the temperature will also provide an early warning to potential fire hazards by notifying personnel when temperatures exceed recommended ranges, thereby preserving the product.

  • Environmental Monitoring

    Environmental monitoring is becoming more important every day in local, national and international policies, showing the environmental awareness demanded by society.

    This fact gives rise to an increase in the amount of legislation that obliges companies to law enforcement. Thus, the necessity of making more pollutants controls means high analysis expenses to the companies, which need to subcontract this service.

    Although applications in this area advance, there is still a clear demand to get new portable and versatile analysis systems for many different application fields such as pollution in environmental or waste waters, monitoring nutrients in agricultural or horticultural water as well as general process control in chemistry industry. Because of the number of enviromental analysis required, there is a need for screening and monitoring measurements of these compounds at contaminated areas.

    Traditional monitoring techniques are typically based on laboratory analysis of field-collected samples that require considerable effort and expense, and the sample may change before analysis. Moreover, the equipment currently available is too large and expensive and it cannot be made portable.Alternatively, microfluidic and electrochemical sensor technologies can contribute to the development of new portable monitoring systems, complementing standard analytical methods for different environmental monitoring applications.In this way, the decentralization and integration of all those typical analyses is the paramount importance in order to reduce cost, simplify the analytical process and make more accessible these technologies to end-users. The development of portable, robust, and accurate Lab-on-a-Chip systems to monitor priority compounds such as contaminants, explosives, chemical warfare agents, inorganic and organic ions is a demand of modern society. Portability allows analyses to be carried out outside of the laboratory, minimizing the risk of contaminating the sample and leading to a faster response time at a lower cost.

    Thus, MicruX solutions and technologies open the gate to develop portable and esay-handly Lab-on-a-Chip devices in order to improve pollutants in-situ analysis in a very economic and efficient way.

    High quality gas sensor solutions for landfill

    State-of-the-art systems enabling easy monitoring of CO2 and CH4 gases. Capped Landfill Sites produce a range of gases, mostly methane and carbon dioxide. Legislation requires that these gases are safely removed from beneath the cap to avoid a physical explosion due to the build-up of pressure beneath the cap. Safe disposal usually entails burning such as flare stacks, internal combustion engines or by processing to produce Methane gas fuel. For large sites with access to power distribution infrastructure internal combustion engines are used to generate electricity which is fed into the local electricity grid. All of the above safe disposal process require the measurement of the Methane content (and in many cases the CO2 concentration). Edinburgh Sensors provide gas sensors for both Methane and CO2 that can be integrated into landfill gas processing systems enabling easy monitoring of these gases.

    Monitoring solutions for the flow monitoring areas

    Many large combustion plants are now required to monitor mass emissions of major pollutants and to do so requires an accurate measurement of stack gas velocity. The VCEM 5100 is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It has several key advantages, firstly the sensors optics are not in contact with the hot and dusty environment, the VCEM 5100 can monitor gases at temperatures exceeding 10000C and the analyser requires minimal maintenance. The VCEM 5100 can be used in extremely dust environments such as SCR’s when dust loadings exceed 10g/m3. The VCEM 5100 is in full compliance with EN/ISO 16911 part 2.

  • Sewage Treatment Plants and Flow Sensors for Industry Application

    In sewage treatment plants, flow sensors are primarily installed for internal reasons. Ultrasonic flow meters are used to control the flow velocity in partially filled and fulfilled pressurized pipes, specific plant components, for leak detection or to control the use of additives. International regulations such as the EU-Directive for handling municipal waste water require flow metering for a continuous surveillance of waste water flow. Defective flow monitoring in sewage-treatment plants can therefore influence their operation, but there can also be legal or environmental consequences.

  • Turbidity Monitoring

    The monitoring of Turbidity is key requirement of the water industry in both water supply and water recovery systems. Within the water supply process, monitoring of turbidity allows operators to assess the efficiency of filters for particulate removal through the process. Similarly, with water recovery (Waste Water Treatment Works), the measurement of turbidity is a key parameter to track the removal of particulate through the process. CTG can provide turbidity measurements with the UniLux sensor, or provides turbidity as one of the parameters available within the 3 channel TriLux. For applications requiring turbidity measurements compliant to ISO07027:1999, CTG can offer the TurbiLux Nephelometer.

    Waste Sorting - CRT Glass Sorting

    End of life TV sets and computer monitors require to be recycled to maximise the level of material recovery, and to meet the requirements of the EU WEEE Directive. CRT glass is the largest item by weight. However, because of the 2 different types of glass used in CRT manufacture, the glass fractions have to be sorted to achieve a separation of the 2 type of glass, i.e. panel glass sorted from funnel glass. X-TRACT separator is able to sort the panel glass from the funnel glass. It does it by comparing their different atomic densities, and analysing the data from the X-Rays using a bi-chromatic sensor system. X-TRACT is the first industrial application for any dry mechanical density sorting.

  • Disposal and Cleaning Equipment for Waste Water Industy

    Drinking water is not the only area requiring flow monitoring. The disposal and cleaning of waste water also requires flow meters. Waste water used to be dumped directly into the soil or an open channel. As awareness has increased, most discharges are now treated to assure long term sustainability. Modern water treatment plants are highly complex systems that require the use of flow sensors to monitor flow velocity in open channels for waste water discharge. Likewise facilities for waste water collection and clarification plants need regular data on flow rate. The use of radar non contact flow measurement and ultrasonic doppler flow meters are particularly efficient. HydroVision can complete flow measurements in all of these areas.
