Filling level gauges for oil tanks, water tanks and cisterns can save home owners, tenants as well as the world of industry and people who run businesses a lot of bother. It’s something many are familiar with: you thought the oil tank was half full, but all of a sudden the fuel oil has run out and it’s cold in your house. Or you’re planning to water your garden, but realise a little too late that the water tank or cistern are empty. These are, of course, scenarios that you would prefer to avoid.
You could naturally check the filling level regularly with a measuring stick, but with an oil tank in particular, this isn’t usually so easy. After all, the operator has to climb into the tank compartment and clean the oil from the measuring stick afterwards.
If a filling level gauge is installed in the tank or container, however, all you need to do is take a quick look at it and you’re in the picture. In this context, various types of filling level gauge are available.
Digital filling level gauge for oil tanks and cisterns
For the digital monitoring of the contents of oil or water tanks, GOK offers its SmartBox range. On the one hand, the SmartBox line includes different versions of the display units and their functions; on the other, it is possible to choose between various probes and/or sensors. We present the basic variants in a compact form below.
Local filling level gauge
SmartBox 1, 2 and 3 display the current filling level in the oil tank or the water level of the cistern on site – in litres, centimetres or percentage volume. While the SmartBox 1 “only” displays the filling level, the SmartBox 2 can also carry out switching functions via two floating relays. In this respect, the operator can define limit values at which the relay switches, and therefore control a solenoid valve (not included in the supply), for example. This means that if a filling level falls below a specific level, the withdrawal switches over to a different tank.
The SmartBox 3 “only” has one floating relay. Accordingly, it also offers the possibility to indicate the surpassing or falling below of a freely-definable limit value both visually (via an LED) and acoustically (via a buzzer) on the device itself.
The SmartBox MINI has similarities with the SmartBox 1, but is battery- rather than mains-powered. The connection of a level probe is not possible either, as the SmartBox MINI only works in combination with a type FSA-E level gauge. However: if the filling height of the oil or water tank to be monitored does not exceed the limit of 250 centimetres, the SmartBox MINI can be the right choice.
Filling level gauge with remote data transmission
If you would like to monitor the filling level of oil tanks or cisterns “remotely”, at GOK, you can choose between the basic functions GSM and NB-IoT. In the case of both GSM and NB-IoT, the configuration is identical to the local filling level gauge: a probe measures the filling level and the SmartBox displays the current value.
The NB-IoT variant of the SmartBox is also able to transfer the data to www.smart-inspector.com, although not via GSM, but via NB-IoT – a radio standard which is used during the networking of devices in what is referred to as the Internet of things.
Filling level gauge in the local area network (LAN)
As its name suggests, thanks to the integrated LAN connection, the LAN version of the SmartBox transfers the measured filling levels of the oil tank or water tank to the local network.
Operators can therefore obtain filling levels and defined system information (burner faults, etc.) using any end device which is registered in the network (e.g. smartphone or tablet).
Filling level gauge for up to 4 tanks
If the term “PRO” appears in the product name, the SmartBox isn’t able to monitor just one tank; it can monitor up to four. The tanks can also have different configurations and/or contain different media. The PRO variants can be found in this info-graphic.
Analogue/mechanical filling level gauge for oil tanks and cisterns
GOK offers three different variants for measuring the contents of oil tanks or cisterns on an analogue basis.
If the oil or water tank has an available opening, the type FSA level gauge is suitable. This measures the filling level via float principle. A screwed-on display issues the current filling level to the operator in centimetres.
If there is no available opening on the tank, the tank spy retrofit kit is an alternative. In addition to the mechanical filling level gauge, the set contains all the components for creating a tank opening, inserting the float into the tank and sealing the tank tightly again.
Last but not least: the type IAP remote level gauge measures the current filling level in the tank using a pneumatic procedure and displays it on a percentage scale.
