Tank Alarms & Overfill Valves

The OLE SmartGuard remote tank level monitor is designed for use on static and mobile fuel tanks to allow tracking and fuel level monitoring. The SmartGuard is fitted with a sim card which is connected to an online portal where the tank contents can be viewed. This provides details on the location of the tank, as well as a notifications or any sudden fuel loss and a low level alert.

Please note there is an ongoing yearly charge for the use of the sim card/web portal. The first year is included in the price.

The O.L.E T5020 is a high accuracy electronic gauge for use with fuel tanks that are up to 10 metres high. Designed for use outdoors, the T5020 tank gauge features an IP65 rated enclosed, and an easy to read backlit display which indicates the contents of the fuel tank as a percentage, and in litres.

The T5020 provides a continuous reading of the contents inside the tank, and comes equipped with an alarm to also act as a leak/overfill alarm.

Thanks to the design, this electronic tank gauge can be used to give accurate readings of any shaped tank.

CT5020 tank gauges come as standard with 4-20mA outputs and Modbus RTU/RS485, so can be connected to BMS (Building Management Systems).

The Filstop 2" Overfill Prevention Valve is designed to act as the fill point for both metal and plastic tanks. The valve physically closes the inlet to the tank when the fuel level inside reaches it's maximum during a fuel delivery. This prevents damage to the tank, and environment as well as the costs associated with cleaning spilt fuel.

The steel tank version screws straight into the 2" BSP Inlet, whereas the plastic version requires a hole to be cut into the top of the tank for fixing via locknut.

Maximum Flow Rate – 580lpm

Minimum Flow Rate – 50lpm

Leak Rate when closed – 2.5lpm

Max Working Pressure – 7 Bar (Tested to 8 bar)

Max Spike Pressure – 12 Bar

Min Working Pressure – 0.15 bar

Tank Fitting – 2″ BSP Parallel Male Thread

The Cleanfill 2" Overfill Prevention Valve from Lafon can be fitted to a tank as a piece of safety and environmental protection equipment. This overfill protection device can be used on fuel and diesel storage tanks that are filled by gravity flow or a pressure pump system. When the tank is full, the valve will close preventing any further fluid from being dispensed into the tank. There is also a version available to be used on AdBlue™ storage tanks, a fluid which is known as DEF in America and other countries.

The GSM Text Alerter is a remote fuel tank level monitoring device suitable for fuel and oil tanks. This simple to install unit allows the user to set up four trigger inputs, which upon activation sends a customised text message to up to eight mobile phones. This oil tank monitor is designed to alert the user to a low fuel condition, or alert of a high level should they require to know when the tank needs emptying. By setting the probes at half full and low level, the Text Alerter can also be used to alert of a sudden drop in the fuel level when receiving two texts in short succession, which may indicate theft or tank containment failure.

There is also a version of this tank level monitoring device available without the probes. This is designed to be connected via its simple, clean contact inputs, to another device such as the output relays on a fuel tank alarm or the relays on the Piusi Ocio Gauge.

The Oil Drum Level Probe is designed for use with any of the single zone CTS tank level alarms to indicate that the oil level within a drum has reached the specified high level. The primary application of this level switch is to prevent an overflow situation when filling a drum in a waste oil storage system.

This single tank level alarm probe is designed for use with the CTS tank alarms, specifically to alert of either a high or low fluid level in water and chemical tanks. Constructed of polypropylene with a polyethylene cap, this tank level switch is suitable for use with many chemicals although we recommend that material compatibility should be checked.

This single tank level alarm probe is designed for use with the CTS tank alarms to alert of a high or low level on tanks containing fluids with a high viscosity or containing debris. The primary use of this level switch is for use on waste oil tank alarms for containing oils that need recycling or disposing of in garage and workshop applications, as due to being encapsulated reliable cut off is ensured even with the presence of particles. The supplied weight can be attached to the cable at any desired length to adjust the switching height in high and bund applications.
