Density Measurement Applications Only

Measurement Site Preparation

Can the Ultimo Density Meter’s percussion sensor (SRM) be mounted at any point on the pipe?

Your literature says that the Ultimo unit requires no maintenance. How about those clamps holding the sensor and bolts in pipe supports that may loosen over and debris that falls on the sensor?

Where can I find the required torque values when I assemble the pipe support system for the Ultimo density meter?

Installation

What about the pipe construction? What are the minimum and maximum wall thicknesses and are there any types of pipes that are unsuitable for the Ultimo Density Meter?
Arrow Down Icon
Material processing, such as in mining, dredging, or fracking industries, generates heavy vibrations. Your density meter is based on percussion—does it create its own vibrations? How does the Ultimo Density Meter measure under the influence of these ambient/system vibrations?
Arrow Down Icon
I found two serial communication cables in the shipping box. One is labeled RS 232, and the other is labeled RS 485. When should I use them? Are they interchangeable?

SRM (Sensor) & DPM (Transmitter)

Does Ultimo have a concise guide to show me how to install and set up the sensor?
Arrow Down Icon
How will I know if the sensor is correctly tightened to the pipe with the screw-lock hose clamps?
Arrow Down Icon
Can I attach the SRM to a metallic or anon-metallic pipe using a  hose clamp?
Arrow Down Icon
How do I verify the transmitter works correctly when you turn the power ON?

Calibration

Is calibration required, and is it done on-site?
Arrow Down Icon
Once calibrated, will it ever need to be re-calibrated?
Arrow Down Icon
If the SRM ismoved to another pipe of the same size, will it need to be re-calibrated?
Arrow Down Icon
How many calibration methods are available for the Ultimo Density Meter?  
Arrow Down Icon
Which calibration method ensures a higher measurement performance?
Arrow Down Icon
Are any spare parts needed?

Operation and Measuring and Accuracy

How does coating on the pipe's inside wall (scaling) affect the accuracy of the Ultimo Density Meter?
Arrow Down Icon
What are the temperature ranges? Is it suitable for 250°C?
Arrow Down Icon
Is it affected by ambient or process temperature variations?
Arrow Down Icon
Is it affected by pressure variations?
Arrow Down Icon
Is it affected by material flow variations?
Arrow Down Icon
What output protocols are available?
Arrow Down Icon
Can the Meter output the density readings and simultaneously record them with its built-in datalogger?
Arrow Down Icon
Is there more than one model of the Ultimo Density Meter depending on pipe  diameters and density ranges?
Arrow Down Icon
Will Ultimo Density Meter work on partially filled pipes?
Arrow Down Icon
What is the unit's response time, and how often are measurements taken?
Arrow Down Icon
Are any assumptions required on key parameters to output the % Total Solids (TS) by density measurement? Are you assuming a constant value for the density of solids and liquids to get the % solids? Given that our ore will have some variability in density, will this assumption significantly affect the unit's accuracy? I suspect this is a limitation inherent in all devices.
Arrow Down Icon
Can we calibrate the Ultimo Density Meter at zero flow velocity?
Arrow Down Icon
Can the pipe layout affect the performance of theUltimo Density Meter?
Arrow Down Icon
How tolerant is the calibration to minor errors in the pipe dimensions (e.g.,manufacturing tolerances)?
Arrow Down Icon
Are there any assumptions required on key parameters in order to output the % solids by density measurement? You are assuming a constant value for density of solids and liquids in order to get the % solids? Given that our ore will have some variability in density; will this assumption significantly affect the accuracy of the unit? I suspect this is a limitation inherent in all devices?
Arrow Down Icon
Do we need to train (calibrate) sensor over known density (% of solid) fluid? Can we calibrate at zero fluid velocity on the same range as operational?
Arrow Down Icon
How do ambient vibrations affect the measurement? Does the sensor need to be tuned to a specific background noise? What happens if the background noise changes during the measurement?
Arrow Down Icon
Can the pipe layout affect the performance of the Ultimo Density Meter?
Arrow Down Icon
How tolerant is the calibration to small errors in pipe dimensions (e.g. manufacturing tolerances)?
Arrow Down Icon
Can more than two calibration points be used (e.g. a calibration curve from more extensive data)?
Arrow Down Icon
Is a one-time connection from a laptop for configuration sufficient, or is an ongoing connection between the device and a PC required? What is the minimum version of Windows required?
Arrow Down Icon
Is there a method for displaying alarm and failure status of the instrument on a plant HMI?
