Flour Mill Level Control Problem Solved

at Cargill Flour Mill in Port of Albany, NY

In the spring of 2000, a large Cargill Flour Mill in Port of Albany NY was attempting to address a difficult level control problem.  Through the "College of Hard Knocks" the plant personnel had just determined that their significant investment in "Brand X" ultrasonic level transmitters was a huge problem.

Although they had been sold on the fact that these units would function well on their 84-foot tall concrete flour silos, they had repeatedly experienced overflows.  

Much time and effort was spent to rectify the problem; however, they were unable to reliably detect when the silos were full.

The problem was caused by the fact that upon filling the silos with flour, a thick cloud of dust filled the entire space within the vessel.  The ultrasonic signal was unable to penetrate the dust and reliably measure the level.

Fortunately for Cargill, Princo became aware of their problem and got involved.  It was   determined that the "real" issue was to detect when the silo was "full" to prevent overfilling.  They needed a "reliable" point level controller. 

The Princo series L3500 was the ideal choice, as it has both the sensitivity and the stability plus FM approval for installation in Class 1, Divisions 1 & 2, Groups C, D, E, F, & G hazardous locations.  

Due to the light powdery consistency of flour, it has a very low effective dielectric constant.  Therefore, to obtain a reliable, repeatable trip point, Princo designed a special flange mounted probe.

Due to their experience with the "Brand X" supplier, Cargill was very demanding of Princo and insisted on: on-site factory start-up assistance, a 100% Application Guarantee, on-demand rapid response factory tech support, and of course, competitive prices and deliveries.

As a result, Cargill Flour Mill in Port of Albany NY purchased and installed more than 100 of these units.  They were installed during the summer of 2000, and have been providing satisfactory service ever since.
