FAQ – MG8350 Magnetic Float Level Transmitter

1) What distinguishes a magnetic float level transmitter from a magnetic level gauge?

A magnetic float level transmitter not only provides local indication but also delivers continuous electrical output signals. The MG8350 converts float position into 4–20 mA and HART digital signals, enabling real-time remote transmission and integration with control systems.

2) Can the MG8350 measure both liquid level and interface level?

Yes. The MG8350 supports measurement of both single liquid levels and liquid–liquid interfaces. It is suitable for applications where the density difference between phases is ≥ 120 kg/m³, such as oil–water separation or chemical layering processes.

3) How does the MG8350 perform in fluctuating process conditions?

The MG8350 maintains stable output even under dynamic conditions such as foam, turbulence, or temperature variation. Its signal stability is enhanced by intelligent damping settings (0.2–30 s) and low temperature drift (<0.01% per °C).

4) What installation options are available for the MG8350?

The MG8350 is available in top-mounted and side-mounted configurations, with probe lengths from 900 mm to 6000 mm, making it adaptable to tanks of different heights and geometries.

5) Is the MG8350 suitable for hazardous environments?

The MG8350 is designed for use in hazardous areas and can be supplied with certifications such as FM, CSA, Ex, and SIL. The dual-chamber housing further enhances operational safety in flammable or explosive atmospheres.

6) What level of accuracy can be expected from the MG8350?

The MG8350 achieves measurement accuracy up to ±0.5%, providing reliable continuous level data for process monitoring and control in industrial applications.

7) How does the MG8350 support long-term operation?

With corrosion-resistant wetted materials (stainless steel + PTFE lining), robust mechanical design, and non-contact magnetic coupling, the MG8350 is engineered for long-term stability with minimal maintenance requirements.
