Powelectrics Deliver a ‘Connected Sensor’ Solution To Improve Safety and Efficiency & Reduce Environmental Risk and Costs

Posted on 05 Jun 2019

Powelectrics work with many environmental businesses, from sewer and pumping station applications and noxious gas monitoring to water level management for wildlife and flood alerts. Our IoT technology connects sensors to the cloud, enabling critical data and alarms to be seen and timely action to be taken.

We have delivered several ‘connected sensor’ solutions for a major supplier of oil industry and environmental services, aimed at protecting critical infrastructure and making businesses more resilient to unexpected events.

For this Industry 4.0 project, our customer wished to improve safety and efficiency at a multi-tank waste transfer station, which receives oils collected from garages, machine shops and fast food outlets and mixed fuel (typically when the wrong fuel has been pumped into a tank).

Prior to installing our kit, the only way to know the tank levels was for an employee to climb to the top of eight large tanks and take dip readings. This created a safety hazard for the individual and it was time-consuming, meaning it might not be prioritised at busy times and may be done later than planned. As a consequence, when levels were finally measured, tanks could be fuller than expected, requiring an emergency collection to avoid the risk of over-spilling.

Emergency collections are usually expensive and inefficient. Over-spilling of waste oils creates safety and environmental risks and are also expensive, because the site may need a clean-up operation or may even be shut down until the area is safe. Powelectrics have delivered an M2M solution to resolve these issues and risks.

SPS hydrostatic level sensors are installed in each of the eight tanks. The SPS range offers simple installation, proven reliability and great value. They are widely used for fuels, water, waste, lubricants, chemicals and foodstuffs. The range includes versions that combine temperature and level sensors, PTFE cable and 316 stainless steel to suit aggressive applications, ATEX versions and those with hygienic fittings for food and beverage applications.

The eight tanks are relatively close together, which means only two of our Metron2 telemetry devices are needed, as each Metron2 has four channels, making these award-winning telemetry devices particularly cost-effective on multi-tank sites.

Metron2 is compatible with thousands of sensor types and available with external, battery and solar power options. Metron2 offers 4 analogue inputs, optional 5 pulse inputs and 2 optional relay outputs. Supplied in a robust, weatherproof IP67 enclosure & operating from - 25 to +65°C, it is suited to many environments and applications.

For this project, level data is reported every 10 minutes, to MetronView, Powelectrics standalone cloud with customisable dashboards, reporting and alerts.

Now, regular level data can be easily viewed by authorised personnel on any web-enabled device. High-level alarms are set up for individual tanks. Staff are alerted when critical levels are reached and collections arranged to minimise disruption.

Nobody needs to climb on the tanks and staff are freed up for more productive activity on site. The risk of an overspill is dramatically reduced along with the safety and environmental risks and the expense of either emergency collections or clean-up operations. There is also an operational benefit in having such reliable and frequent readings, in terms of trend analysis and strategic planning.

Powelectrics connect the world of sensors and the Internet of Things offering 25 years’ sensor experience and our own IoT devices & platform. Our solutions are employed in many industries including chemical, pharmaceuticals, Adblue, fuels, oils, LPG, lubricants, food and beverage, waste & recycling, landfill & leachate, agriculture, utilities, pumping and environment, rail and security.
