How Nielen optimizes its routes with Four Data connected oil and gas gauges in Belgium
Summary

Managing fuel oil and gas tanks is a major challenge for Belgian distributors, both in terms of service and operational efficiency. Located in Mabompré, in the Houffalize region of Wallonia (Belgium), Nielen Joseph SRLa regional distributor of heating oil, gas and pellets, has chosen to equip some thirty sites with Four Data’s connected sensors to improve level monitoring and delivery planning.
A growing need for tank visibility in Belgium
Between the crèches, schools, sports centers and companies it supplies, the Nielen team has to manage dispersed installations, with volumes that are sometimes difficult to track manually. Like many distributors in Belgium, the company was faced with several constraints:
- time-consuming manual surveys ;
- sometimes unnecessary travel ;
- no real-time visibility of consumption ;
- risk of breakage or late delivery.
Visit connected oil and gas gauges were seen as a solution for making fleet management more reliable and optimizing rounds.
Simple installation of oil/gas collectors on tanks
According to Nielen, the first positive surprise was the ease of installation Four Data sensors, including gas sensors (Hall effect) compatible with Rochester gauges. The company notes that is fast, with no need for major intervention, which has enabled the sensors to be deployed progressively at dozens of sites.
This simplicity is a key factor for distributors wishing to equip large numbers of tanks without tying up their teams.

Measurable time savings on tours

Thanks to remote level monitoring, Nielen estimates it saves around five minutes per customer. For a complete tour, this represents between one and two hours per daydepending on the area served.
This optimization is due in particular to :
- the disappearance of many manual controls,
- the ability to organize tours according to real needs,
- reducing unnecessary mileage.
Connected oil and gas gauges can improve efficiency without changing the basic organization.
Measurement accuracy: a key point for gas
For gas tankers, the accuracy of sensors is a point often raised by distributors. Nielen confirms this point: discrepancies between transmitted data and actual volumes remain below 3%.a level deemed reliable for organizing deliveries and monitoring consumption.
This precision contributes to better anticipation and supply planning.
Reliable alerts to prevent shortages
The company also emphasizes the reliability of the email alert systemwhich automatically alerts you when gas or oil levels fall below a critical threshold. This avoids emergency situations and reinforces continuity of service for equipped professionals and institutions.

A concrete benefit for distributors in Belgium
For Nielen, the use of connected oil and gas gauges offers a pragmatic pragmatic improvementwithout radically transforming working methods. The company’s main concerns are :
- a tool to reduce the time spent on touring,
- more accurate visibility of actual levels,
- simplified planning,
- more reliable operation thanks to automatic alerts.
These feedbacks illustrate the growing interest of Belgian distributors for connected sensors on oil and gas tanksparticularly on sensitive installations such as schools, crèches and communal facilities.
