1. In ship operation, ensuring accurate monitoring of fuel level in fuel tanks is extremely critical
for safe navigation and energy efficiency management. Accurate measurement of fuel tank oil
level can guarantee the stable oil supply of ship power system, and at the same time avoid oil
spill accident and protect the marine environment.
Therefore, the choice of measurement technology for fuel tank oil level on ships is particularly
important, and guided wave radar level meter is highly respected in this field for its high
precision and high reliability.
Ship fuel tank oil level has the following characteristics: First, the fuel oil has a high dielectric
constant, which is conducive to the propagation of electromagnetic waves; Second, when the
ship sails at sea, the internal environment of the fuel tank may be complex and variable due to
shaking, pressure changes and other factors, requiring the level meter to have good stability and
anti-interference; Third, the ship has limited space, the fuel tank has a variety of designs, which
requires that the liquid level meter can be adapted to both the narrow space and can be Adapt to
different shapes and sizes of the cabin.
The core advantage of guided wave radar level meter is based on the principle of microwave
pulse phase measurement. It establishes level information by transmitting microwave pulses
and receiving the reflected phase signal. Since the propagation of microwaves is not affected by
common factors such as temperature, pressure, density, etc., the guided wave radar level gauge
is able to provide accurate fuel level data even in the complex and changing environment of a
ship’s fuel tank. In addition, these level gauges typically have a small form factor for easy
installation in compact ship spaces.
The tanker of a transportation company carries a large amount of crude oil across the sea, and
real-time monitoring of the fuel level in the fuel tank is especially critical during long voyages.
In the past, the tanker used a traditional measuring instrument, but due to the fluctuation of
seawater and fuel consumption during long voyages, the instrument would often drift and
accumulate errors, resulting in unreliable oil level readings.
To solve the problem, the company decided to install guided wave radar level meters on its
tankers. When selecting specific products, the technicians fully considered the challenges of the
ship’s special environment, picked a guided wave radar level meter model suitable for working
in harsh conditions, and carried out a series of tests on the actual ship to verify the product.
After the installation of the guided wave radar level meter, the measurement accuracy of the
fuel level in the fuel tank on the tanker was significantly improved, realizing a high precision
reading of ±1mm.
As the guided wave radar level gauge is less susceptible to external environmental influences,
maintenance requirements are significantly reduced, thus lowering operating costs. More
critically, the accurate fuel level measurement data enables the crew to better manage fuel
consumption and optimize route planning, ensuring the economic and safe operation of the
tanker.
The application of guided wave radar level meter not only greatly improves the accuracy and

2. reliability of fuel level measurement in the fuel tank, but also helps ship operators to reduce
maintenance cost and enhance the safety of navigation, which is the best choice for fuel level
measurement in the fuel tank.
