Fuel Monitoring System in The Dangs: Diesel Clarity on Saputara Ghat and Forest Roads

Each of the three sensors costs ₹19,999 inside the package, so in The Dangs the decision rests on the vehicle and the roads it climbs. Three questions settle it quickly. How far does the tank sit from the place where the tracker will go? Is the tank steel or plastic? And would you prefer to avoid a battery in the sensor, or avoid a cable running along the underside through mud and rain?

Omnicomm LLS-AF 4 is wired. It takes power from the vehicle and sends its reading along a cable into the tracker, inside a sealed body made for dust, water and washing. For a coach or resort shuttle that climbs to Saputara day after day, through heavy monsoon spray and muddy roadsides, a probe with no battery and a fixed cable is the steady choice. Once calibrated, it simply keeps reporting.

Mercetech and Mielta Fantom both connect by Bluetooth. Mercetech suits a pickup or tractor whose tank sits well behind the cab, where a long cable would be exposed to stones and water on village roads. Mielta Fantom adds Bluetooth 5.0, a tilt reading and a steel flange made for steel or plastic tanks, with set-up done through Mielta's phone app. On ghat roads, a tilt reading helps make sense of a graph that rises and falls with every bend.

Both wireless sensors depend on internal batteries that wear down over time and are treated as consumables outside the warranty. BearTech confirms the model and probe length only after seeing the tank, and a comparable model may be supplied if the listed one is unavailable. A small operator can fit wired sensors on coaches and wireless ones on pickups and still follow all of them in one Trakzee Premium account.

The tempo traveller. On a monsoon weekend it brings a group from Surat up to Saputara, waits while they visit the lake and viewpoints, takes them to Gira Falls near Waghai and returns. The record shows a fill on the plains, a steep fall on the climb, a near-flat line while parked at the top and a gentler fall on the way down. The owner sets the litres against the hire charge and knows what a weekend trip truly costs.

The resort coach. It shuttles guests between Saputara and points along the ghat several times a day. Because the route is short and repeated, its daily litres should stay close together. When they rise for two weeks, the manager sends it for brakes, tyres and filters, and the following days show whether consumption eased. A sharp fall while it stood overnight in the resort parking area would stand out at once.

The bamboo pickup. It collects bamboo and farm produce from villages around Ahwa and carries them to a depot or trader. Its graph shows a morning refill, a slow fall over winding village roads and a halt while it is loaded. Litres per trip, compared week by week, tell the owner whether a new route or a heavier load is pushing consumption up.

The hill-farm tractor. Near Subir it works terraced fields during the rice and finger millet season, then stands for days. The refill log shows one fill before work, the ignition record shows engine hours, and the line stays flat while the tractor is parked. At harvest's end the family knows how much diesel the season used, measured rather than guessed.

BearTech gives an accuracy of about 95% on a sound tank after proper fitting and calibration. That is good enough to show when diesel went in and when it fell, but it remains a working figure, not a laboratory measurement. It will not agree with a pump dispenser to the litre, and a small difference between slip and graph is normal.

In The Dangs, slope matters more than anything else. On the Saputara ghat a coach spends long minutes nose-up on the climb and nose-down on the descent, and diesel shifts towards one end of the tank. The probe sees a different level on every bend, so the graph rises and falls while the vehicle moves. That movement is the tank tilting, not fuel appearing or vanishing. Sloshing on rough village roads adds smaller jumps.

The answer is to judge refills and losses only from readings taken while the vehicle is parked on level ground, before and after the event. The flat parking areas at the top of the ghat or in Ahwa give dependable figures; a lay-by on a bend does not. Tank condition, rust inside, and water or sludge in the diesel also affect readings, so mention any repaired or patched tank before fitting.

Network is the other limit. Readings travel over Airtel, and in valleys, forest stretches and mist-bound bends the signal can fade, so the live view may pause and catch up later. A gap means no network, nothing more. Above all, the package reports and alerts. It cannot lock a tank, stop an engine or prevent anyone drawing diesel. Keep that in mind on misty monsoon evenings.

Picture a resort coach parked on level ground at Saputara. During fitting, the executive opens a small hole in the upper face of its diesel tank and lowers a probe trimmed so that the tip sits just above the floor. It is then fixed and sealed. The probe senses how much of its length is surrounded by diesel, giving a smooth figure that changes as fuel is used or added.

The figure passes to the Teltonika FMB920 tracker in the cab, through a cable with Omnicomm or over Bluetooth with Mercetech and Mielta Fantom. The tracker already knows the coach's location, its speed and whether the ignition is on. It combines all of that with the diesel figure and sends the record through its Airtel data SIM, so each reading carries the moment and the place it was taken.

In Trakzee Premium the coach appears on a map with litres in its tank. The day's graph shows refills as steps up, climbs as steep falls, waits at the top as near-flat stretches and any fast drop as a step down that triggers an alert. Consumption and mileage reports present the same data by trip, day or month, on a phone or on the web screen at the resort desk.

Calibration links the probe's signal to actual litres. On fitting day, readings are matched against known amounts of diesel in that particular tank, with the coach standing level. If the tank is ever replaced or welded, or the probe removed, the matching has to be repeated. Tell BearTech before such work and the figures stay trustworthy. Left undisturbed, it holds through many seasons.

A Saputara resort or tour business often has a manager who owns the vehicles, a travel desk that books trips and someone in accounts who pays the pump. Trakzee Premium lets the account holder add users, each with a separate login, so all of them can see the same diesel record from a phone or computer without sharing the main password. Tell BearTech who needs access when you order. Each person signs in under their own name.

The manager reads exceptions. A quick look each morning at alerts, refills and each vehicle's consumption shows which coach used more than usual on the ghat, or whose level changed while parked overnight. Anything unusual can be handed to the travel desk with a time and place attached, which keeps the follow-up specific and fair to the driver.

The travel desk plans with the same record. Before a group sets off down to Surat or up from Waghai, a look at the level shows whether a fill is needed first, since pumps in the hills are fewer than on the plains. Trip and halt reports beside the graph show how long vehicles waited at viewpoints and how much diesel those waits used, useful when quoting longer itineraries.

The accounts person reconciles. Each refill has a date, a time and a rise in litres, ready to be ticked against pump slips and driver advances at month end. Litres and kilometres per vehicle feed the rates charged for tours. With everyone working from one record, there is less disagreement about figures and more attention on what they suggest doing. Over a season, that becomes routine.
