Magnetic Level Gauges

Magnetic Level Gauges on the principle of communicating vessels; therefore, the level in the measuring tube is equal to the level in the tank. Inside the measuring tube is a float containing a ring magnet. Because the float floats on the medium, the position of the ring magnet indicates the liquid level via the wafers the outside of the measuring tube.

The float in the measuring tube is completely pressure-free by design and has no magnetic or mechanical guidance. This makes this float safer than floats that are pressurized with gas beforehand. If necessary, depending on the pressure and specific gravity, Hadro can pre-pressurize the float for you.

Based on the process data below, it is easy to select a float that will remain afloat on the medium.

• Medium
• Specific gravity
• Workload
• Temperature

Each slat in the indicator rail is equipped with an embedded permanent Magnetic, making the device resistant to shocks, vibrations, and high temperatures. Even damp and/or corrosive environments are no problem for our Magnetic Level Gauges.

The Magnetic Level Gauge available with plastic or stainless steel wafers. The wafers be mounted in a plastic, aluminum, or stainless steel housing.

Because the wafers are white wafers one side and red on the other, the liquid level is very clear and easy to read, even from a distance—even in dark areas.

Using the included “Templates,” you can easily set any limit values for your desired level.

Magnetic switches can be used to generate an output signal. By using multiple switches, you can set up a pump control system (pump on/off) or configure a high/low alarm.

In addition to or instead of the switches, a transmitter can also be installed; this transmitter provides a 4–20 mA output signal.

Magnetic Level Gauges also suitable for indicating the interface between two different liquids in a tank.

In addition to PED, our devices are also approved by: LR (Lloyd’s Register) and BV (Bureau Veritas) for the maritime industry.
