Fuel Monitoring System in Porbandar: Diesel Levels for Fish Vans and Port Trucks

Choosing the sensor is the only real decision in a Porbandar fuel monitoring system, and price does not enter it, since all three cost the same ₹19,999 in the package. What matters is the vehicle. How far is the tank from the place where the tracker will be mounted? Is it a steel tank or a plastic one? And would you accept a battery in the sensor to avoid laying a cable?

Omnicomm LLS-AF 4 is wired. It draws power from the vehicle and sends readings along a cable, so there is nothing inside to run down. For trucks on the long haul to Rajkot, Junagadh or Jamnagar, which may run for years with little attention, that is a steady choice. Its sealed body copes with salty air near the harbour and dust from the quarries, and wiring a truck chassis is routine for the fitter.

Mercetech and Mielta Fantom are Bluetooth sensors. Mercetech helps where the tank is far from the dashboard, as on a long bus or a truck with a rear tank, since nothing has to be threaded along the frame. Mielta Fantom uses Bluetooth 5.0, senses tilt and temperature, and carries a steel flange that bolts onto steel or plastic tanks; it is configured with Mielta's mobile app. Fish vans and farm tractors with mixed tank types are where it is usually discussed.

Both wireless sensors run on batteries that count as consumables outside the warranty. BearTech confirms the model and probe length after seeing your tank, and a comparable model may be supplied if one is out of stock. Send a photo of the tank and the vehicle type on WhatsApp, and we will suggest a sensor and say why it suits that vehicle.

The fish van. When the fishing season reopens after the monsoon, an insulated van loads catch at the harbour and leaves for an inland market. Time matters, so the owner watches how long the van waited at the quay and whether it filled on the way. The record shows both, and a refill on the highway appears as a step with time and place, ready to match with the slip. Fresh catch cannot wait, so a long halt is costly in more ways than diesel.

The stone truck. A truck loads building stone near the Barda side and heads for Rajkot. It crawls out of the quarry, then runs steadily on the highway. Over a few weeks, the owner learns what a normal stone run costs in diesel. When a trip uses noticeably more, the halts list and the refill log come first, then a calm conversation with the driver.

The Madhavpur tourist van. A diesel tempo traveller takes visitors from Porbandar to Kirti Mandir, the Sudama temple and on to Madhavpur beach, waiting at each stop. If the engine idles for the air conditioning, the line slopes down through the wait. The operator can then price waiting fairly for the next booking, using real figures. Winter weekends bring the busiest bookings.

The Ranavav school bus. A diesel bus runs a fixed village route into Ranavav each term day. Weekly diesel should change little. When it rises for a few weeks, tyres, filters and injectors are checked before anyone questions the driver. The school office gets a clean diesel figure per route for its accounts and its fee planning.

Porbandar faces the Arabian Sea on the Saurashtra coast, with Junagadh, Jamnagar and Devbhumi Dwarka as its land neighbours. The Bhadar river reaches the sea along this coast and the low Barda hills rise inland. Porbandar town is the headquarters, and Ranavav and Kutiyana are the other main talukas. Roads run north to Jamnagar and Dwarka, east to Junagadh and Rajkot, and along the shore to landing points such as Navibandar and Madhavpur.

The sea drives the first share of diesel. Insulated vans carry fish from the harbour and Navibandar to inland markets, and the port keeps trucks moving through its gates. Fishing generally pauses during the monsoon months, roughly June to August, and landings rise when the season reopens, so van traffic follows the same rhythm through the year. Ice plants and cold stores near the harbour add their own short runs.

Land produces the second share. Building stone from the Barda side, salt from the coastal pans and groundnut and cotton from the fields go by road to Rajkot, Junagadh and Jamnagar, hours away. Groundnut and cotton reach the market from about October, after the monsoon, and wheat in spring. Long distances mean long gaps between the owner and the tank.

Visitors and schools add the rest. Guests come for Kirti Mandir, where Mahatma Gandhi was born, the Sudama temple and the beach at Madhavpur, mostly in winter and around holidays. School buses run village routes into Porbandar and Ranavav each term day. Monsoon storms can flood low coastal roads and sometimes close the port for a few days, and the diesel record shows how such weeks differ from ordinary ones.

The litres on screen are a careful estimate. BearTech quotes about 95% accuracy on a sound tank after proper fitting and calibration, which is good enough for trends, comparisons and catching sharp changes. It is not a laboratory instrument, and a gap of a litre or two against a pump slip is normal and no cause for worry.

Movement and slope move the reading. A stone truck crawling out of a quarry throws its diesel around; a fish van parked on a sloping quay tilts its tank; a tractor standing on a field bund does the same. To judge a refill or a loss, compare readings taken with the vehicle parked on level ground before and after the event. Harbour aprons and quarry floors are rarely flat.

Tank and fuel condition matter too. Salty coastal air can rust older tanks, dents and odd shapes distort readings, and water or sediment in the diesel shifts the figure. Signal is the other limit: near the Barda hills and on some inland stretches cover can be weak, and the live view pauses until the tracker reconnects and sends what it stored. A gap is a network pause, not lost diesel.

Then the terms. The package reports and alerts; it cannot lock a tank, stop an engine or keep anyone away. Wireless sensor batteries are consumables outside warranty. There are no returns, refunds or exchanges, so send tank size, material and a photo first. Fishing boats, salt-pan pumps, generators, stationary tanks, cars and two-wheelers are ask-first cases. We would rather say no than sell the wrong thing.

BearTech has no office or team in Porbandar. It works from Bhopal and has been in vehicle tracking since 2014. For a Porbandar order, an executive travels from Bhopal to the place you choose, whether a transport yard, a spot near the harbour, a quarry or a school depot in Ranavav. The client pays travel and stay, and BearTech names that amount before you place the order.

Delivery takes about 2 working days, stock permitting, and then the date is agreed. The monsoon pause in fishing, when vans are less busy, can suit fish-van owners; for school buses, a holiday is easiest. Port areas have entry rules, so arrange any pass the executive needs in advance. Group several vehicles on one visit to share the travel cost.

Prepare a few things. Park the vehicle on firm, level ground with the tank reachable and reasonably clean of salt crust, grease and fish scale. Send a photo of the tank opening ahead so the probe length can be planned. Keep the registration papers ready and have someone on site who knows the routes and who should get alerts once fitting is done.

On the day, the executive inspects the tank, cuts an opening in the top, trims the probe to the tank's depth and seals it. The FMB920 is connected and paired with the sensor by cable or Bluetooth, and calibration links readings to litres. The vehicle is added to Trakzee Premium and the login is tested on your phone, so you see the live level before the executive leaves. Payment is in full at fitting, or by token-amount COD for orders outside Bhopal.
