9. Leak & flood detection (draft tube, sumps, pits, etc.)

All fluid leaks in a hydroelectric plant related to the operational equipment are contained in strategically located sumps and pits to be disposed of periodically. Magnetrol offers a variety of Level switch and transmitter technologies to monitor, detect and actuate measures to manage leakage throughout the facility.

Solution

The Eclipse 706 GWR or the Pulsar R86 non-contact radar transmitters are used as continuous level tracking devices so that PLC and DCS systems can automatically operate draining pumps to dispose of collected fluids in sumps and pits.
Electronic and mechanical switches can also be used for the same purpose.
Displacer units can control up to 3 pumps or a combination of pumps and alarms while the FLS (flood level switch) unit can be used to detect and alarm the presence of just a few inches of fluids on the ground where there is not supposed to be any.

Eclipse® 706 guided wave radar transmitter

The Eclipse^® Model 706 high performance transmitter is a loop-powered, 24 VDC level transmitter that is based upon the proven technology of guided wave radar (GWR). Encompassing a number of significant engineering accomplishments, this leading-edge level transmitter is designed to provide measurement performance well beyond that of many of the more traditional technologies.

Utlilizing "diode switching" technology, along with the most comprehensive probe offering on the market, this single transmitter can be used in a wide variety of applications ranging from very light hydrocarbons to water-based media.

The innovative angled, dual compartment enclosure is now a common sight in the industry. This enclosure, first brought to the industry by Magnetrol^® in 1998, is angled to maximize ease of wiring, configuration, and viewing of the versatile graphic LCD display.

One universal ECLIPSE Model 706 transmitter can be used and interchanged with all probe types, and offers enhanced reliability as it is suitable for use in critical SIL 2/3 Certified safety loops.

The ECLIPSE Model 706 transmitter supports both the FDT/DTM and enhanced DD standards, which allows viewing of valuable configuration and diagnostic information such as the echo curve in tools such as PACTware^™, AMS Device Manager, and various HART® Field Communicators.

Magnetrol

Model FLS floor-mount level switch

The Model FLS Flood Level Switch is a float operated, liquid level control designed for bracket mounting at floor level sumps or troughs.

The proven Magnetrol magnetic coupling is employed to convert float movement to actuate a single snap-action dry contact switch mechanism. The switch is factory set for ¾" level differential for off-on control, alarm or safety shutdown service.
