Vibrational meters: built for liquids with no suspended solids
A vibrational meter infers density from a change in vibration. It is a medium-cost meter built for liquids.

How a vibrational meter reads density
Density is inferred from a change in vibration. Most physical sensors are Coriolis or vibrational.
It is used on liquids, in duties such as water treatment and chemical processing. Cost is medium.

Where it falls short on slurry
Here is where vibrational typically trades off on slurry, as stated in the technology overview.
- It cannot handle suspended solids.
- Small diameters.
- Physical sensors tend to be very large or very small. Vibrational meters sit at the small end.

What a Red Meter does differently
A vibrational meter is built for liquids and cannot handle suspended solids. The Red Meter reads the full bore of a slurry line. You get density, temperature, pressure and vibration from one device at the same moment.
The Red Meter installs inline between flanges, with no bypass and no probe in the flow. It uses a Class 1 laser, so there is no radioactive source to license. Readings are continuous and go to a third-party system if you want them there. Remote support is built in.

Vibrational against a Red Meter
| The Red Meter | Vibrational | |
|---|---|---|
| Principle | Class 1 laser reads deflection of the full bore. Vibration is a separate reading. | Change in vibration |
| What is measured | Full bore | Small diameters |
| Radiation source | No radioactive source | No |
| Slurry limits | 2 in to 40 in pipe, rated for 0 psi and above. | Cannot handle suspended solids. Small diameters. |
| Typical applications | Mining, dredging, oil and gas, and power. | Pharmaceutical, water treatment, chemical. Liquids. |
