Low power pressure sensors optimised for IoT

September 2017 Sensors & Transducers

Keller, a leading manufacturer of pressure sensors, is at the forefront when it comes to implementing IoT solutions. IoT processes are highly customised and require continuous development. Keller has worked with international companies to develop numerous smart, customer-specific total solutions in various sectors and applications. Fuels are ideally suited to management by automated, smart processes. The remote monitoring of fuel levels in heating oil, diesel and petrol tanks is of value to mineral oil companies, petrol station owners and property managers alike.

Keller has developed the EasyOil remote monitoring system in partnership with a Swiss mineral oil supplier. This system is the key selling point for customers in 80% of the contracts concluded for heating oil deliveries. The order process is thus: the pressure and level of oil are measured at the lowest point in the tank, the current content in litres is calculated according to the shape of the tank, and the data is transmitted via GSM. A special feature of this application is the customer-specific software. In addition to the current data such as fill level, consumption and order history, it also tracks oil prices, which are updated twice a day. This combined information optimises the order process, allowing customers to stockpile when the price of oil is low or the tanker is close by.

Because there is a risk of explosion at petrol stations, any pressure transmitter taking measurements in this type of environment must be intrinsically safe. For this application, the GSM-3 remote transmitter has been extended to include a box with built-in safety barriers that limit the electric output of the measurement system within the zone at risk of explosion (the ex zone), thus preventing sparks.
