The multi Level Switch Series UNS 2000 can be supplied with up to 6 switchpoints (see max. switchpoints). Besides the float operated reed contacts to detect liquid levels, the UNS 2000 can be supplied also with a temperature sensor and/ or temperature contact(s), which are to handle as switchpoint(s) - please note max. switchpoints! A wide selection of mounting elements, electri-cal connections, various materials and options allow you to “de-sign” your own switch, within the given dimension limits, for your particular application. Very long units or large flanges can cause high shipping and installation costs and “split” versions might be the answer. Consult us for the best combination.The min. dimensions are based upon the medium water. Depend-ing on the density of other fluids this dimension can vary several millimetres. The contact modes (NO or NC) are defined on the ba-sis of an empty tank and for installation through the top or through the bottom (when specified as “-U”). When not specified otherwise we will set the switch position for density 1 (water) and the switch action to be on moving upward. Temperature sensor (PT100) and/ or the temperature switch, a Bi-metall hermetically sealed ele-ment, are installed only in the bottom of the stem. That means: Dimensions B + 10 mm with temperature sensor PT100) Dimensions B + 40 mm temperature switch (TP)

LevelLevelSite® Accessories
Barksdale offers a line of limit switches that can be positioned on the outside of the LevelSite® housing to activate alarms, pumps, or valves when the fluid reaches a prescribed level. The number of limit switches that can be attached to the LevelSite® is limited only by the available space on the exterior surface of the housing. Switches can be located in any radial position 360° around the housing. This flexibility allows other control components to be mounted at the same level. Limit switches are easily installed with stainless steel clips and a screwdriver. Switches rated for use in hazardous areas are available (an approved safety barrier device may be required).

As a supplement to the visual indication provided by a LevelSite®, Barksdale’s continuous Tank Level Indicating (TLI) system provides a continuous 4-20 mA output signal, which can be used in remote process controls and indicators. The TLI is mounted externally on the LevelSite® housing with stainless steel clips. Since it does not come in contact with the media, it is easy to maintain and remains accurate and reliable through many years of service.

Limit Switch for Bypass Level Indicator
Features / DescriptionAll GK switches have bi-stable reed contacts. They can be mounted in any position around the tube of a magnet-controlled level indicator with stainless steel clamps, however the cable direction should preferably be downward.The magnet system in the float will switch over the contact whenever the switch is passed. This permits an arbitrary arrangement of many switches on the tube surface without the switches disturbing each other.The switch position must be checked before installation; it can be set with a ring magnet or the float.The switch hysteresis depends on the distance to the magnet system in the float and is smallest when the switches are installed closely along the indication rail.

Operating Principle
LevelSite® Supplemental Guide General Specifications
LevelSite® is a magnetic rotary indicator. It is a reliable level measurement system for applications with operating pressures to 4500 psig (310 bar), operating temperatures to 600°F (316°C), and with liquid to a minimum specific gravity of 0.5049.
LevelSite®’s visual indicators and electrical switches are isolated from the liquid; the tank remains sealed from the surrounding environment (See Figure 2). Accidental spills from sight-glass breakage are eliminated.LevelSite® consists of 3 major components: the float housing, a magnetic float, and the rotating flag assembly. The float housing is an engineered pressure vessel which is externally mounted to the tank. The float housing is designed to handle the same temperatures and pressures found in the tank. It is fabricated from a variety of materials, depending on the application. The alloy models are usually stainless steel. Engineered plastic models use polyvinylchloride (PVC), polypropylene (PP) or polyvinyliden fluoride (PVDF). Other materials are available on request.The float (See Figure 3), is equipped with a permanent ring magnet assembly. This assembly rides at the surface of the liquid contained within the float housing, rising and falling as the liquid in the tank rises and falls.As the float moves up and down, a magnetic flux field maintains continuous contact with the rotating flags mounted on the outside of the float housing. Flag rotation occurs as the flux

field from the permanent ring magnet acts on the magnets embedded in each flag (See Figure 4). The rotating flags below the level of the liquid in the float housing show their red side and those above show their white side.The special permanent ring magnet design provides a 360 degree magnetic flux field. This allows the rotating flag assembly, limit switches and continuous level sensors to be located anywhere around the float housing. Troublesome guide wires and rods, and magnetic tape on the indicating flag housing are eliminated.
LevelSite®’s rotating flag assembly provides maximum visibility and has a resolution of 1/2” (12.7 mm). Rotating flags have a square profile with embedded permanent magnets. The flux field generated by the ring magnet in the float interacts with the flag magnets causing them to rotate as the float moves up and down inside the housing. After the flags rotate to the new position, the embedded magnets lock the flags in place, making the flags less sensitive to vibration (See Figures 4 and 5). LevelSite®’s rotating flags are mounted in a housing
fabricated of extruded aluminum or polycarbonate. The assembly is attached to the outside of the float housing with stainless steel clamps. The ends are sealed against dust and moisture. Since the flags are never in contact with the liquid, they never need to be cleaned and they can’t discolor. If the rotating flag assembly is accidentally crushed, there is no danger of a liquid spill.The rotating flag assembly is available in aluminum or polycarbonate and measures 1.18” (30 mm) and 1.02” (26 mm) wide, respectively (See Figure 6).

LevelLevelSite® Supplemental Guide General Specifications
Aluminum flags are offered in an anodized finish of red and silver or painted in red and white. Anodized flags are suitable for service up to 400°F (200°C); painted versions can be subjected to 600°F (316°C). A glass pane protects the flags. The housing is extruded, black anodized aluminum.Polycarbonate flag housings are clear and impact-resistant. They offer 180° visibility of the flags; level can be seen from front and sides (See Figure 5). Housing and flags can withstand temperatures to 250°F (121°C). Standard flag colors are red and white.
LevelSite®s are designed according to the unique requirements of each application. Based on information provided by the user regarding operating temperature, pressure, and “normal” specific gravity of the liquid, a float is selected appropriate to the application. Maximum and minimum conditions are evaluated to ensure that the LevelSite® will function not only at the normal condition, but at each extreme. Maximum temperature and pressure are parameters used to design the pressure vessel (float housing).Barksdale applies their own standards in the design of LevelSite®s. Figures 8 and 9 can be used as a guide in selecting the ANSI class flanges and materials appropriate for your temperature and pressure conditions.
Barksdale’s LevelSite® is a unique system that can be custom designed for many types of applications, from a stand-alone, no-power-required level indicator to a fully-integrated electronic component within a process control system. It can be supplied with process connections located for any of the four standard patterns: top/bottom, top/side, side/side, or side/bottom (See Figure 7). For applications where tank-side mounting of the LevelSite is not practical or desired, top mounted versions are available. Liquid interface configurations require three process connections (See Figure 7).
Quality and dependability are built into every Barksdale LevelSite. As a registered ISO 9001 manufacturer, Barksdale meets the most demanding international standards. LevelSite® can be certified to ASME, ANSI, DIN, BSP and other codes.

LevelSite® Supplemental Guide Operating Instructions
General InstallationLevelSite®s are measuring instruments and must be properly treated as such. Make sure that all parts are available and the connecting flanges on the tank correspond to those on the indicator. The float and limit switches (if applicable) are enclosed in a separate box. Remove the bottom connection flange (1) of the float chamber and insert the float with the top uppermost. Replace the bottom flange with the gasket, fixing it to the chamber by tightening all the bolts securely. The LevelSite® must be raised slowly and carefully so that the float is not damaged by severe impact.
It is essential to ensure that the flanges on the tank are accurately aligned with the flanges on the LevelSite®. Non-alignment of the flanges causes distortion of the float chamber (2) with the possibility that the float (3) will stick. The Levelsite® must always be mounted vertically. Before commissioning, the flags in the flag assembly (4) must be aligned by means of a magnet so that they all show the color white (polycarbonate) or silver (aluminum). NOTE: It is essential for all flange bolts, the vent-plug (5) and the drain-plug (6) to be fully tightened.
The electrical limit switches (7) may be attached at any point in the range on the indicator bar by means of a stainless steel clip. Ensure that the stainless steel clips are installed under the flag assembly. The maximum electrical switching capacity is specified on the nameplate of the limit switch (7) and must not be exceeded. IMPORTANT: The operation of the LevelSite® is based on the magnetic field principle. Ferrous strips, clamps, or screws must not be used.
LevelSite®s are always application specific. The most important technical data such as pressure and temperature limits are specified accurately on the nameplate (8). However, the sales drawing for the model number referenced on the nameplate is specific and detailed to the application and is the governing specification document. Before commissioning, a check must be made to ensure that the technical data shown on the nameplate corresponds exactly with the plant requirements. NOTE: Test pressure and test temperature of the plant must NOT exceed the specifications.
The transmitter is installed on the side of the LevelSite® housing, utilizing stainless steel clips, with the transmitter’s probe along the housing. The transmitter may be used in addition to a visual indicator (rotating flag assembly) to provide electronic monitoring of fluid level. If the transmitter is used with a flag assembly, it may be necessary to slide the transmitter’s clamps under the flag assembly. The transmitter is supplied with a mark on its probe. This mark must line-up with the centerline of the process

connector on the LevelSite®. If the transmitter’s probe spans the entire measuring range (center-to-center of the process connections), the probe will be marked to show the measuring range. Electrical Connections: Ground the transmitter’s housing if necessary. The cable length may be up to 3 miles. The transmitter is designed to be maintenance-free and is not field-serviceable. If the unit is not operating properly, replace the entire unit. For more information, refer back to “Tank Level Indicating Transmitter”.
