MG8530 Series Float Level Transmitter

Technical Specifications

Applications

1) Heavy Hydrocarbon & Asphalt Storage Systems

The MG8530 is ideal for monitoring level and interface in heavy hydrocarbon tanks, asphalt reservoirs, and bitumen processing units. Its angular displacement sensing mechanism maintains stable measurement in highly viscous and adhesive media, while the large turning angle of up to 135° supports reliable level tracking in fluctuating tank conditions.

Key advantages:

• Designed for high-viscosity liquids and sticky media

• Stable operation under temperature variation up to 450 °C

• Suitable for interface detection with density difference ≥ 50 kg/m³

2) Slurry Handling in Mining & Mineral Processing

In mineral slurry pipelines and sedimentation tanks, the MG8530 provides continuous level and interface measurement despite suspended solids and turbulence. Adjustable damping (0.2–30 s) and mechanical stability ensure accurate signals in harsh operating environments.

Key advantages:

• Resistant to vibration and particulate interference

• Dry calibration reduces maintenance downtime

• Output via 4–20 mA + HART for process control integration

3) Lubrication and Grease Distribution Systems

The MG8530 is applied in industrial lubrication tanks and grease distribution units where traditional level sensors fail due to thick media. The robust float mechanism and dual-chamber explosion-proof design ensure safe operation in enclosed mechanical systems.

Key advantages:

• Reliable measurement in grease and oil-based fluids

• Explosion-proof structure for confined installations

• Pressure resistance up to 6.3 MPa

4) Multi-Phase Liquid Separation Equipment

The MG8530 is suitable for separators, settlers, and decanters where liquid–liquid interface monitoring is required. Its ability to detect interface changes with minimal density differences enables accurate control of separation processes.

Key advantages:

• Interface measurement with density difference ≥ 50 kg/m³

• Measurement range from 380 to 1600 mm

• Accuracy up to ±1% with temperature-compensated output

FAQ – MG8530 Float Level / Interface Transmitter

1) Why is the MG8530 suitable for highly viscous and sticky liquids?

Unlike conventional float transmitters, the MG8530 uses an angular displacement sensing mechanism instead of linear float movement. This design reduces the influence of adhesion and resistance from viscous media such as asphalt, grease, and slurry, ensuring stable level measurement even when the medium has high viscosity or impurities.

2) What is the advantage of the 135° large turning angle?

The intelligent version of the MG8530 supports a maximum turning angle of 135°, which significantly expands the measurable level range and improves sensitivity to level changes. This is especially useful in tanks with limited installation space or irregular level fluctuations.

3) Can the MG8530 measure liquid–liquid interfaces?

Yes. The MG8530 supports interface measurement when the density difference between two liquids is ≥ 50 kg/m³. This makes it suitable for separation processes such as oil–water, chemical phase separation, and multi-layer liquid systems.

4) How does the MG8530 maintain accuracy under temperature variations?

The MG8530 features automatic density compensation and temperature drift control, with temperature influence less than 0.01% of span per °C. Combined with an accuracy of ±1%, it ensures stable measurement in processes with large temperature fluctuations.

5) What does “dry calibration” mean for the MG8530?

Dry calibration allows the transmitter to be calibrated without filling the tank or interrupting the process. This significantly reduces commissioning time and is particularly valuable in hazardous or high-temperature environments.

6) How does the MG8530 handle mechanical vibration and shock?

The transmitter adopts reinforced mechanical structures and vibration-resistant electronic modules. It is designed to withstand transportation impact, installation shock, and long-term vibration in industrial environments.

7) What signal outputs and integration options are available?

The MG8530 outputs 4–20 mA analog signals with HART digital communication, enabling seamless integration with PLC, DCS, and SCADA systems. Adjustable damping (0.2–30 s) allows optimization for different process dynamics.

8) Is the MG8530 suitable for hazardous areas?

The MG8530 is available with explosion-proof and intrinsically safe certifications such as FM, CSA, Ex, and SIL, and features a dual-chamber isolation structure for safe operation in flammable and explosive environments.
