Ultrasonic Clamp-on flow meter for alumina hydrate

Panametrics demonstrated a successful test

Summary
At an aluminum production plant in Guangxi, China, many electromagnetic flow meters were used for alumina slurry measurement. However, sometimes the electromagnetic flowmeter electrodes were found to be coated or damaged by the slurry. The customer wanted to find a simple and reliable measurement solution that would not impact on production.

Challenge
The customer required the following from the check meter:
1. Installation without process interruption
2. Ability to measure slurry flow with stable and reliable data
3. Battery power

Solution
A demonstration was run using Panametrics’ Transport
PT900 with C-RS 0.5MHz transducer. It was installed on a dual
traverse mode despite the technical difficulty it brings with a
reflective path on slurry

Result
The test was successful. The diagnostics exhibited healthy
parameters confirming measurement reliability and accuracy.
The customer subsequently replaced several faulty Mag
meters with Panametrics Aquatrans AT600 Clamp-on
Ultrasonic Flowmeters.
The customer was pleased with the clamp-on flowmeter
solution citing:
• Easy installation and set up
• No maintenance
• Limited and universal spare parts
• Large pipe diameters coverage with the same set up
• No need for production downtime

Application
• Process step: Precipitation
• Medium: Alumina hydrate
• Pipe material and size: CS and DN400 (16”)
• Pressure: 0.7 MPa (101 psi)
• Temperature: 58°C (136°F)
• Flow: up to 700 m3/h (3,082 GPM)

Benefits:
• Easy installation
• Longer battery life for continuous
measurements
• Easy data logging
• Reliability and performance
