9 Tank Overfill Alarm Designed to provide an audible and visual alarm on high fuel level, with Test and Mute facility. Constructed using IP 65 Rated GRP enclosures with an oil resistant membrane concealing lamps, push buttons and audible alarm. Alarm panels require a 230V ac supply whilst providing a 12V dc control circuit to a dedicated tank mounted float switch configured with a make on rise switch. All Tank Alarm options have integral volt free changeover contacts rated at 5 amps 230V ac which provide remote signalling in the event of alarm. The range covers Single, Twin or Three Tank Alarm Panels, together with a High/Low option and a combined Tank & Bund high level alarm. Full range of Float Switches available. In operation, prior to the commencement of fuel delivery, the Test button should be depressed to ensure that both the audible and visual alarms are in working order prior to the commencement of the fuel delivery. The alarm panels emit an audible alarm on sensing a high fuel level, a red warning lamp will also illuminate. By pressing the Mute button, the audible alarm will be silenced, the red warning lamp will remain illuminated whilst the fuel level remains at high level. Dimensions are: 172mm wide x 130mm high x 76mm deep. Fixing centres are: 4 off 4.2mm diam. holes, 163mm wide x 113mm high.

10 Float Switches Float Switches are available in the following styles: As single switches for High fuel level indication as shown above, working in conjunction with the FEL Valves range of Tank Overfill Alarms whereby an audible and visual alarm is generated by detection of a high fuel level within a tank using a standard make on rise float switch assembly. Also shown above is a Bund float switch with flexible lead, Ref Twin float switches, can provide High and Low switch points for indirect pump start/pump stop applications or to provide pre-set alarm indications, perhaps for overfilling and fuel reorder points. Four float assemblies usually provide a combination of alarm and pump start/pump stop functions, whereby the lower and upper floats give Low Low and High High indication. Customers may choose between Make on Rise or Make on Fall switch orientation together with the switch point dimensions taken from the top of the tank into which the float switches are to be installed. FEL Float switches are manufactured to a robust design, using stainless steel stem, floats and float stops and a brass process connector with 1 BSPP male thread. The terminal housing is of cast aluminium to IP67, whilst the internal switches have a standard rating of 1.0amp 230V ac. The maximum switch depth is 3000mm. Customers should also specify where float switches are to be used on inductive loads, as back EMF protection may be required. FEL float switches can be made suit individual customer requirements for switch rating, orientation, switch depth and materials of construction, please enquire for further information. FEL Valves Product Code / /4 General Description Single switch for High Fuel level Indication usually at 200mm below top of tank. Twin float switch assembly, customer to specify switch point dimensions. Four float switch assembly, customer to specify switch point dimensions. Page 10

12 Digi-Level Contents Gauge & Overfill Alarm Digital readout of contents, programmable in litres, gallons or US gallons. Programmable for individual rectangular or cylindrical tanks, with accuracy to +/- 0.5% Available for 230V ac or 24V dc power input. Provides 24V dc excitation voltage for 4-20mA signal. The digital controller can provide up to four, 2 amp 230V ac volt free relay set points which can be individually set to energise or de-energise on a rising or falling edge alarm. 4-20mA or 0-10V Retransmission for remote contents reading. MODbus RTU output connectivity option. The digital controller can be used with a wide range of tank mounted sensors which include pressure sensing, capacitance or ultrasonic types. The sensors can be active or non active for current loop ma generation. Please see separate data sheet. Can be used in conjunction with the FEL Valves overfill alarm PCB. This configuration utilises one of the digital controller alarm set points to operate the high fuel level alarm and can do away with the need for a tank mounted float switch, although the overfill alarm may still be used with a float switch if required. The controller can be used to control liquid levels within a tank or vessel by actuating valves or pumps whilst signalling contents level to remote locations for alarm Page 12

13 Standard IP65 ABS enclosure with 20 amp 2 pole isolator can house a digital controller as well as overfill and bund alarms. Dimensions are 188mm wide x 278mm high x 180mm deep. For the combined Controller and overfill alarm, all connections are pre-wired and terminated within the enclosure, leaving only the final field connections to be made. Page 13

14 The FEL Digital Contents Gauge System utilises a 2 wire stainless steel immersion sensor which generates a 420mA signal. The sensor diameter is 30mm allowing a comfortable fit through a 1 tank connection. Standard sensors come with 5m of attached PUR cable, although lengths up to 20m can be specified. Digilevel and overfill alarm enclosures are supplied fitted to our Fill Cabinets, with conduit entries and fixing supports formed during manufacture reducing site installation to a minimum. Programming and pre-commissioning are standard features. Custom Fill Point Cabinet generally to IP54 with toughened glass vision panel, weather seal, internal partition and drip tray. Page 14

17 Hydrostatic Gauge Equipment Available as Mechanical or Electro/Mechanical systems, Hydrostatic gauge Systems provide a constant read out of tank contents, using internal or external pressure sensors and a range of gauge heads, covering sizes from 100, 160 and 250mm in diameter. Our range of hydrostatic gauges also includes pressure transducers and electronic gauges, as well as current loop amplifiers and direct, hydrostatic switching modules. In operation, the standard hydrostatic gauge is mechanically powered from an internal or externally tank mounted pressure sensor, whereby, the head of liquid within the tank pressurises a metal diaphragm within the sensor. In turn, the sensor diaphragm exerts a pressure which is used by the gauge head to indicate tank contents. This pressure is transferred from the tank mounted sensor/diaphragm assembly to the gauge head via a copper capillary which is sheathed in a terylene reinforced PVC tube. The mechanically driven pressure signal, generated by the tank sensor can also be used to provide a 4 to 20mA analogue signal, via a pressure transducer and forming a current loop. In turn, this proportional signal may then be used to create switching points using a current loop amplifier as well as to provide an analogue readout using an electronic gauge head. The 4-20mA analogue signal makes the FEL gauge system ideal for use in conjunction with a building management system. Gauge head construction is in stainless steel, for both mechanical and electrically driven systems, whilst tank sensors have a ¾ process connection and are usually manufactured from mild steel, with an electron beam welded stainless steel diaphragm. Interconnecting capillary is available to a maximum length of 50m and retransmission of the 4-20mA signal extends the logistical usage to more than 1000m. Page 17
