Fluidwell Instruments launches Presense Level Detection Sensor

Adequate level detection of bulk materials like liquids, powders, pellets, granulates and other bulk material inside a vessel or container can be very difficult. It gets even harder when low dielectric materials and/or harsh environments, like pressurized, abrasive, hot and/or corrosive environments are involved.  The resulting reliability issues have a negative effect on costs and downtime. To solve these problems, Fluidwell Instruments, a division of Fluidwell, launches the Presense LDS 300, a “Field Time Control” (FTC) based Level Detection Sensor, which comes with three stainless steel (AISI 316L) probe types: adaptive and/or rod probes for short and (non-)vertical mounting, and cable probes for long and suspended (vertical) mounting.

Key applications
Application overview PresenseThe Presense LDS 300 Level Detection Sensor is a FTC technology based, microprocessor controlled sensing level switch, designed to indicate the actual level, and to switch at preset levels of: liquids, powders, pellets, granulates and other bulk material inside a vessel or container. It is suitable in a wide range of applications, but especially for industries with extremely low dielectric bulk products (solids and liquids) or rough and electrically polluted environments. Choose from three stainless steel (AISI 316L) probe types: adaptive and/or rod probes for short and (non-)vertical mounting, and cable probes for long and suspended (vertical) mounting.

Advantages
- Especially suitable for low dielectric materials and measuring in harsh, pressurized, abrasive, hot and corrosive environments;
- Special digital filtering for stable measuring in rough and electrically polluted environments reduces deviations and unscheduled downtime and costs;
- Innovative digital cycle time conversion into FTC counts results in increased production output and reduced downtime;
- Sensor self-diagnostics considerably reduces maintenance costs;
- Robust, sustainable construction, reliable and suitable to operate in harsh industrial conditions;
- Integrated programmable controller with intuitive LCD, LED backlight and a simple two button interface displays continuous level information via a bar graph and a numerical display.

Better results with less costs for an attractive ROI
Presense product overviewLouis Ras, General Manager of Fluidwell Instruments, proudly adds: “With the help of FTC technology we developed a product that really makes a difference in the industry. The Presense Level Detection System has been validated by several large manufacturers, including one of the biggest flour producers in Europe. Their current mechanical level detection system is considerably more subject to maintenance, for instance. With the new Presense their maintenance and downtime costs, combined with improved results on level detecting, are so far reduced that the ROI is only a few months! We targeted their challenge in an innovative way and as a result this company now finds in the Presense a perfect solution for a new era.”

Functionality of FTC (Field Time Control) technology:
Innovative level detection technology for bulk materials
With FTC technology the sensors’ sensitivity increases considerably, making it suitable for adequately detecting various bulk products, even those with extremely low dielectric constants. And still getting more signal with low variation for increased reliability and thus decreasing costs, increasing revenues and clearer insight in running processes. An electric field is generated between the transmitting and the receiving electrode. The cycle time of the FTC sensor changes as soon as solid particles intervene this electric field. This is how the system provides a more reliable and cost effective solution for product detection.
