Ultrasonic Level Transmitter HART Non Contact Type

The MG8750 non-contact ultrasonic level transmitter leverages advanced EchoDiscovery technology. A fully intelligent module delivers 4-20mA analog and HART digital outputs. Its integrated, corrosion-resistant probe features a compact yet rugged build that resists vibration, impact, and variations in medium density or dielectric constant. Offering a wide 0.3–30 m measuring range, it reliably handles liquids, slurries, powders, and high-viscosity or crystallizing media. Quick to install and maintenance-free, it is ideal for highly corrosive acids and alkalis, and can replace buoy, optical-guide, or nuclear-type gauges on site.
