Opus - Manufactured by Fluid ID Systems Limited
Technical DetailsOpus is an electronic overfill prevention system located on the tank lid which is hard wired through an intrinsically safe circuit to the Midas system at the tanker filling point.
The primary function of the Midas system is to prevent tanker misfuels, also to control filling and eliminate storage tank overfills. The Opus probe is installed on the tank lid with the probe section sitting “inside” the tank space at a length that gives the client their preferred safe working capacity level. Once the fuel level in the tank reaches this safe working level a magnetic float system triggers a signal to the Midas at the tanker filling position activating a series of pre-programmed visual and audible alarms to alert the tanker driver to the impending overfill situation. The factory default alarm condition closes the internal butterfly valve by 90% for 20 seconds whilst alarming audibly and flashing a unique sequence of led lights to alert the driver to the imminent full closure. Once the 20 second alarm phase is completed the Midas system logs the time and date of the alarm for full traceability. If the driver has not had time to shut the tanker valve and drain his hose before full closure he can use the

standard Operators key fob to re-activate the Midas; the result will be that the unit will drop immediately into the 20 second alarm loop.
Opus effectively removes the need for mechanical overfill prevention systems thereby avoiding health and safety issues such as engineers working in confined spaces or having to deal with dangerous vapour releases and fuel spillages.
Best practice in line with EN: 13616 “overfill prevention devices for static tanks for liquid petroleum“ recommends that overfill prevention systems should be fully testable and that an annual inspection is performed to confirm functionality. The design of the Opus is such that it can be tested in situ without removal and zero vapour release into the tank chamber. All that is required of the engineer is to remove the Opus cover and manually lift the float system to the high level position. This simple action will produce a visual indicator to the engineer in the tank chamber as well as an audible and visual indicator at the filling point through the Midas system.

How does it work?The device will be calibrated during installation for either Diesel or Petrol products, the system will then instantly read the fuel that’s being delivered and if correct open the valve to allow the filling operation to continue. If an incorrect fuel type is detected the valve will stay closed and the unit will alarm both audibly and visually to alert the driver to the mistake.
The design and development project was initiated following a meeting on a petrol
forecourt with oil company engineers, who indicated that misfuelling storage tanks
with incorrect fuel was a major issue, both environmentally and financially.
Why specify it?
◆ Midas protects your business from costly contaminated fuel uplifts and disposals
◆ Midas ensures there’s no associated disruption to your forecourt
◆ Midas protects your customers from misfuelling their vehicles
◆ Midas protects your business from 3rd party damages and claims
◆ Midas protects your brand image and reputation
What is Midas?A system that is fitted to the above or below ground filling points on each bulk fuel storage tank at petrol filling stations. The unit comprises of a valve with intelligent control that can discriminate between petrol and diesel grades of fuel. The purpose of the unit is to stop the wrong product entering the tank and causing a misfuel.

Midas – Manufactured by Fluid ID Systems LimitedCERTIFICATE NO. 131502
Approvals◆ ATEX – Europe ◆ FM – North America ◆ CSA – Canada ◆ IECEx – International ◆ TR-CU GOST-R – Russia
◆ PCB – microprocessor controlled
◆ Battery life – 5-7 years
◆ Visual warning – LED Lights
◆ Audible warning – Piezo electric sounder
◆ Fail mode – closed
◆ Wireless communication – data capture
◆ Key fobs – motion activated
◆ Hand held Datatec unit – installers tool
Technical DetailsThe Midas utilises a low current high torque motor to operate the control valve. The valve offers a complete seal against product entering the unit from the delivery side and likewise for vapour build up from the tank side. This ensures that when the cap is opened there is no excessive release of voc vapours around the delivery driver position.
All communication to and from the Midas is done wirelessly via infra-red communications. The system is fully automated and requires no interaction from the tanker driver except for a prompt to “wake up”.
Motion activated key fobs are required to interact with the Midas for functions such as normal operation, override and reset. Override and reset function keys can be kept in store or secured in DCD cabinets in the event of an attempted misfuel. Any communication with the unit in regards to calibration, parameter changes, data capture and diagnostics is done via a hand held Datatec unit.
Due to the low power requirement and mechanical wear the unit requires minimal maintenance. Midas is self powered by an internal battery pack, and power calculations done on a site experiencing two deliveries per day indicate a typical battery life expectancy of 5-7 years.

Opus is used in conjunction with Midas; now not only does Midas protect from misfuelling but also from overfilling the fuel storage tanks, eliminating the need for any mechanical overfill valves within the tank.
Opus is fitted to the top of the tank lid and its probe sensor initiates closure of the Midas inlet valve once the fuel tank is nearing an overfill.
