It measures or estimates the fuel level using its specified sensor method. Read the model instructions for tank compatibility and display or app features.
Fuel-Level Monitoring and Remote Fire-Safety Parts
Running low on heating oil can stop a boiler at the wrong moment. MacBlair lists a Magnus HAWKi smart radar monitor and a Watchman Sonic tank sensor kit in its oil gauges and alarms section. The same listing also contains remote-acting fire valves, so check which device solves the problem before ordering.
A tank monitor estimates fuel level and may display it away from the tank, depending on the model. Check tank shape, sensor fitting, power requirements and any connectivity or app conditions. A reading is not a substitute for looking for leaks or damage during routine checks. The complete tank system sits within plumbing and heating.
Remote fire valves perform a different safety role on a heating-oil supply line. The listed options vary by temperature rating and cable length; those details must match an installer's design. Check compatibility with the oil boiler and compare the separate fire valve range before buying.
Oil Gauge & Alarms FAQ's
Not necessarily. Many devices monitor fuel level, not every leak. Check the exact functions listed for the product.
No. Tank shape, depth, opening, material and wireless range may limit compatibility. Check the manufacturer’s fitting guide.
They are separate safety components in the same store category. A fire valve responds to heat on the fuel supply, not to a low fuel level.
It depends on the route between sensing point and valve location. A qualified oil-heating installer should specify the rating and length.
