If you’re running slurry density measurement in an Australian mining operation, you already know the drill. Nuclear gauges work, but they come with a laundry list of headaches: ARPANSA licenses, radiation safety officers, quarterly reporting, disposal liabilities, and that constant background worry about what happens if something goes wrong.
There’s a better way. Red Meters offers a non-nuclear density measurement solution that’s been gaining serious traction in mining, dredging, and tailings management worldwide. And here’s the kicker: it’s now available in Australia through Endless Process Automation, with local engineering support, stock holding, and site commissioning.
Let’s break down why more Australian operations are making the switch.
Why nuclear density gauges are a compliance nightmare
Nuclear gauges have been the industry standard for decades, and they do the job. But the hidden costs and compliance burden often outweigh the benefits, especially for operations in remote Australian locations.
Here’s what you’re dealing with when you install a nuclear density gauge:
- ARPANSA licensing: You need a controlled materials license from the Australian Radiation Protection and Nuclear Safety Agency. This involves background checks, security clearances, and ongoing compliance obligations.
- Radiation safety officers: Someone on your team needs to be certified as a radiation safety officer. That’s training, ongoing education, and responsibility.
- Quarterly reporting: Regular reporting to regulators about source integrity, security, and usage.
- Disposal liabilities: When the gauge reaches end-of-life, you’re responsible for disposing of a radioactive source. That’s expensive and complicated.
- The “what if” factor: Every audit, every inspection, every time someone asks about your radiation sources, there’s that underlying tension.
The real cost of a nuclear gauge isn’t the purchase price. It’s the ongoing compliance burden, the training requirements, the reporting, and the eventual disposal. For many operations, especially in remote Queensland or Western Australia, this overhead simply doesn’t make sense anymore.
Endless Process Automation has worked with numerous sites facing these exact challenges. If you’re evaluating your density measurement options, it’s worth understanding what alternatives exist.
How Red Meters technology works
Red Meters takes a completely different approach to density measurement. Instead of using gamma radiation, they use a patented inline deflection system powered by a Class 2 industrial laser.
Here’s the short version: The Red Meter replaces a section of your pipe with a specialized rubber chamber. As slurry flows through, the chamber flexes microscopically based on the density of the material. A precision laser measures this flex 3,000 times per second, and intelligent algorithms convert that data into accurate density readings.
The key components:
- Rubber chamber: A flanged industrial rubber hose with natural gum rubber lining that matches your pipe diameter. It provides a clear path for the laser to take full-volume readings.
- Laser sensor: Mounted below the chamber, it performs 3,000 interrogations per second without contacting the process fluid.
- Intelligent algorithms: Patented software processes raw sensor data, compensating for temperature, pressure, and vibration.
- Integrated HMI: A 7-inch touchscreen displays up to six parameters simultaneously in numerical or graphic format.
Because there’s no sensor contact with the process, wear is limited to the inside of the chamber. When you’re handling abrasive slurries (common in Australian mining), you can rotate the cartridge 90 degrees to extend its life significantly. No nuclear source to replace, no calibration drift from coating buildup, no radiation safety protocols.
Red Meters specifications and accuracy
Let’s get specific about what Red Meters delivers in terms of performance:
| Specification | Value |
|---|---|
| Accuracy | ±0.25% of reading |
| Measurement rate | 20+ readings per second |
| Pipe sizes | 2″ to 60″ (scalable) |
| Output parameters | Density, % solids, temperature, pressure, mass flow, SG wet/dry |
| Certifications | NIST, OIML, ASTM |
| Communications | 4-20mA, Ethernet, Modbus, Wi-Fi |
| Software | Ruby 2.0 cloud platform |
The accuracy claim is certified, not marketing fluff. ±0.25% of reading means if your slurry is running at 1500 kg/m³, you’re getting readings accurate to within ±3.75 kg/m³. That’s more than sufficient for process control and compliance reporting.
The Ruby 2.0 software platform deserves mention here. It provides cloud connectivity for remote monitoring, data logging, and performance trending. You can check your density readings from your phone, tablet, or control room. For operations running multiple sites or managing remote installations, this visibility is invaluable.
The system outputs continuous data on all parameters, not just periodic samples. This matters when you’re trying to catch process upsets, optimize thickener performance, or prove compliance to regulators.
If you’re working in mining applications, these specifications translate to real operational advantages: better process control, reduced chemical usage, and more consistent product quality.
Applications in Australian mining and industry
Red Meters has been deployed across a range of applications that are highly relevant to Australian operations:
Tailings pond management
Water reclamation from tailings is a critical process, both environmentally and economically. Accurate density measurement lets you optimize sedimentation, maximize water recovery, and minimize fresh water consumption. With increasing scrutiny on tailings management in Australia, having reliable data matters.
Slurry transport pipelines
Whether you’re moving concentrate, tailings, or process slurry, knowing your density in real-time lets you optimize pump speeds, prevent blockages, and maximize throughput. The Red Meter’s continuous measurement beats grab sampling for catching density spikes or variations.
Thickener underflow control
Consistent underflow density is crucial for downstream processes. The Red Meter can feed directly into your control system to maintain setpoints automatically, reducing operator intervention and variability.
Dredging operations
For ports, harbors, and coastal works, accurate solids measurement is essential for project billing and environmental compliance. Red Meters has been used extensively in US dredging projects and is well-suited to Australian marine applications.
Process control circuits
From flotation to leaching, many mineral processing circuits depend on density control. The Red Meter’s fast response time (20 readings per second) makes it suitable for closed-loop control applications.
Australian conditions present specific challenges: Pilbara dust, Queensland humidity, Bowen Basin heat, and the isolation of remote sites. The Red Meter’s rugged construction and minimal maintenance requirements make it well-suited to these environments. No delicate nuclear sources to protect from heat or vibration. No quarterly inspections requiring specialist technicians to fly in.

The Endless Process Automation advantage
Here’s where things get interesting for Australian operations. Endless Process Automation is the local channel partner for Red Meters, which means you’re not dealing with a manufacturer 15,000 kilometers away when you need support.
What this looks like in practice:
Local stock holding
We carry inventory in Queensland, which means shorter lead times for urgent replacements or new installations. No waiting for international shipping when you’re trying to keep a process running.
Application engineering
We don’t just sell boxes. Our engineers visit site, review your application, and specify the right meter for your conditions. Pipe size, slurry characteristics, integration requirements: we handle the details.
Site commissioning
Installation support, calibration, and commissioning are available. We’ll make sure the meter is reading correctly and integrated with your control system before we leave.
Integration expertise
Red Meters communicates via standard protocols (4-20mA, Modbus, Ethernet), but getting it talking to your SCADA or PLC properly requires know-how. We work with Rockwell, Siemens, Schneider, and other major platforms daily.
Post-installation support
When you have questions or issues, you’re calling a Queensland-based engineer who understands Australian industrial conditions, not a support queue in another timezone.
Vendor neutrality
We’re not here to push Red Meters if it’s not the right fit. As an independent supplier, we can source from multiple vendors including Emerson, Endress+Hauser, Yokogawa, and others. If Red Meters isn’t the best solution for your specific application, we’ll tell you and recommend something that is.
This is the value of working with a Queensland-based automation partner who understands local conditions and can provide ongoing support.
Installation and maintenance made simple
One of the practical advantages of Red Meters is how straightforward installation and maintenance are compared to nuclear gauges.
Installation
The Red Meter installs inline, replacing a section of your existing pipe. It’s flanged, so it bolts in like any other spool piece. No bypass piping required, no pressure loss from restrictions, no changes to your pump curves. The unit weighs approximately 700 pounds for typical sizes, so standard rigging equipment handles it.
Maintenance
Here’s the beautiful part: minimal maintenance. The rubber cartridge is the only wear component. When it eventually shows wear (after months or years depending on your slurry abrasiveness), you rotate it 90 degrees to expose fresh rubber. When that’s worn, you drop in a new cartridge. The electronics, laser, and housing stay in place.
Software updates
The Ruby platform receives remote software updates. No technician visits required to patch firmware or add features.
Calibration
Unlike nuclear gauges that drift and require periodic recalibration, the Red Meter’s laser measurement is inherently stable. No recalibration schedules, no calibration drift concerns, no source decay compensation.
Compatibility
If you have existing nuclear gauges, you don’t need to rip everything out at once. Red Meters can work alongside your current instrumentation during a transition period, or replace it entirely. The 4-20mA and Modbus outputs integrate with most control systems without major changes.
