Product Description

Description

The 7ML5221-1BC11 is a SITRANS Probe LU ultrasonic level transmitter engineered for continuous, non-contact level and volume monitoring of liquids and slurries. This device offers a measurement range of up to 6 meters (20 ft) and utilizes an advanced echo processing algorithm to ensure reliable performance in diverse industrial environments. Equipped with a 4-20 mA HART communication output, it allows for easy integration into existing control systems and remote monitoring architectures. The transmitter features a durable PVDF copolymer transducer and a G 2" (BSPP) process connection, making it suitable for a wide range of vessel types and process conditions.

Features

  • Technology: Ultrasonic non-contact measurement for level and volume.
  • Measurement Range: Up to 6 meters (20 ft).
  • Output: 4-20 mA with HART communication.
  • Transducer Material: PVDF copolymer (chemical resistant).
  • Process Connection: G 2" (BSPP), EN ISO 228-1.
  • Enclosure: Plastic (PBT) with 2 x M20 cable inlets.
  • Certifications: General purpose, FM, CSA, CE, C-TICK, KCC.

Applications

  • Liquid level monitoring in storage tanks and process vessels.
  • Slurry level measurement in industrial waste or mining applications.
  • Volume calculation for chemical storage.
  • Wastewater and utility monitoring.

Installation Guidelines

  • Mounting: Install the transmitter in a vertical position, ensuring the transducer face is clear of any obstructions such as agitators, fill pipes, or tank walls that could cause false echoes.
  • Environment: Avoid mounting the unit in areas with heavy turbulence or excessive foaming on the liquid surface, as these conditions can impede ultrasonic wave propagation.
  • Wiring: Use shielded, twisted-pair cabling for the 4-20 mA HART loop to prevent electromagnetic interference. Ensure all cable glands are tightened securely to maintain the integrity of the enclosure.
  • Configuration: Utilize the HART protocol to configure parameters such as tank dimensions, material type, and damping constants during the initial commissioning phase.
  • Maintenance: Periodically inspect the transducer face for buildup; clean using non-abrasive materials to ensure signal accuracy.
